Rose Rosette Infected Shoot by Mark Apgar CC BY-SA 4.0 - Jak na to + styl
Also, glysophate damage can look similar.
Ask a certified Rosarian or your local Rose society.
Thanks Gail. 100% right - and I was thinking to put an info box into the video. You did the next best thing to get into the comments! 2-4D also can mimic some of the symptoms.
Yes! Years ago I was deeply worried that I had an outbreak of RRD but it turned out that a "neighbor" (in the loosest sense of the term) had sprayed herbicide with abandon, not caring who or what else was impacted. Apparently their layer of pea gravel wasn't sufficiently keeping down the weeds.
Hi! Great video. I worked in herbicide drift damage and herbicide soil residue injury for 20 years, just to let you know glyphosate looks nothing like these disease symptoms
Recognizing herbicide damage is a real timeline assessment, you know what I mean right? You’re going to see a plant response over time, and depending on dose, herbicide group, and plant genus, symptoms can vary wildly, but some constants do exist.
Thanks Sandi. With your more trained eye, there are probably distinctions you'd spot right away - but the point on roserosette.org is that to the average gardener, yellowing, stunting, dieback, distorted growing tips and discoloration could be look-alike issues. Here's their write-up: " Many of these symptoms of RRD resemble herbicide drift injury, especially that of Glyphosate, the active ingredient in Round-up®. The commonly-used broadleaf herbicide 2, 4-D can also cause leaf distortion on roses. The only symptoms that may not be present with such poisoning are excessive thorniness and red pigmentation. Such herbicide injury symptoms should disappear in the following year unless the plants are re-injured by drift. Nutrient deficiency may also resemble RRD injury, but will typically affect the whole plant. Therefore, it is important to check for combinations of RRD symptoms over time."
Turning a complaint into an education opportunity - love your work!
Thanks so much Cat!
I would not be afraid to buy roses from you as your straightforwardness reflects your honesty. Thanks for your vids. 🌹
Thanks so much!
Most honorable Rose-Grower ever. Knowledgeable too.
Nothing here in Nanaimo, Vancouver island for rosette disease. Good to know about this disease.
Thank you Jason for caring and getting the word out there. I realize your a small nursery and something like this could be devastating to your business. You could have not said anything and taken care of the situation behind the scenes, but you care enough to share your concerns. Sometimes we push the panic button before we need too, you handled the situation very well. Again thank you. 🍁🍂🍁💚🙃
Thanks Judy. That's one thing this CZcams audience has been excellent for: there's always room enough to tell the whole story and have constructive conversations about it. I'm sure that's not the case in some topic areas, but I'd say it's 98% true with this group.
G'day Jason, I learnt years ago that "complaints were opportunities to excel!". You certainly did that in my mind. The person who complained will continue to be a customer due to your quick response. You have also impressed your followers by your honesty & instruction. Well done. Mike, Brisbane, Australia
Thanks Mike!
I don't even like roses, but I have enjoyed the business aspects of your journey, and your story. Thanks and continue to demonstrate your good customer service and integrity.
Thanks so much!
Thank goodness i'm in the safe zone near the Rose City Portland. I had a concern about one rose from a reputable online nursery few months ago. The first thing I did was of course ---panicking---then the next thing I did was taking a photo and sent to the vendor to confirm. Turned out it was just simply a very rigorous growing. The vendor was so gracious and patiently explained the situation which gained my trust and forever gratitude.
I'm so happy it turned out that way for you!
I've never grown roses until this year and I was concerned about the red new growth, nut I did research and realized it was not unusual and probably wasn't rose rosette. I found your videos on the subject which helped me stay calm and not panic. I live in the Southeastern U.S. right in the heart of the virus, but so far, so good. Thanks for the really good information you share, especially for those of us who are new to roses.
Thanks for sharing your experience. It actually must be tough to keep your nerve when you're in an area with so much exposure tot he disease, and I think that's the right thing: stay calm and don't panic.
This is a good way to deal with the complaint - your videos are great at teaching people not to panic - which was a message I myself needed to hear after buying about $500 of roses!
Very good points. I found the photos and info on the rosette site pretty confusing personally. Almost tossed a rose shrub but my local group helped me calm myself and they were correct.
Hi Jason, You are so conscientious, kind, and helpful Take care and be good to yourself. Not to worry!
I was given a rose that when the new growth came in, the thorns and leaves looked so condensed that it resembled RRv but once it fully leafed out it was completely healthy.
I completely agree with you. Thank you for the information.
I bought a house that had a rose Victorian it was 40 years old I planted a few other roses and they stayed healthy until my house burnt down and lost all rose plants but I was recently in a local nursery a man came in with the rose stem that was quite long he said it was diseased they looked at it and it was not they told him that it was sun scorched and it showed he was over watering I always remind people to put their samples in a bag so if it does have a disease it doesn't spread thanks for informing us I had never heard of the disease
I had problem similar with the long shoot. I cut that shoot off and watched the plant over the summer. I did have the red flush on new growth but no more long shoots and no other signs. So I am now sure it was false alarm for me. I'm glad you brought up this information. I feel good about waiting.
Thank you for this information. I live in Amarillo, Texas. In the past 2-3 years RRD has been brought into our area by housing contractors that purchased infected roses and planted them in several newer housing communities. I am a Randall County Master Gardener (class of 2016) and I manage our Master Garden’s rose garden that is about 20 years old and was started as a test garden mainly with Buck roses and others. I take care of 30 of these old rose bushes and knowing that RRD, which has been confirmed by one of our local nurseries and several other Master Gardeners, is very concerning to me. I am glad to learn about the ongoing effort in researching this virus and I would like to help through donating and educating others about RRD. Your videos are an excellent source for Rose information and I have watched most of them. Thank you for all you do for the benefit of our roses. I wish I could do more but sharing this information with others is the best way for now to get the word out there. Mary
Thanks so much Mary!
I forgot to mention that the imported roses that were infected are red Knock Out Roses. Unfortunately, Knock Outs have been planted in the thousands to the point that it is the main plant everywhere here other then Russian Sage and Boxwoods. The lack of diversity is an problem and will probably contribute to the spread of RRD.
I used to work at a rose farm here in Australia, I've never heard of this disease so maybe we don't have it here. But this just sounds like normal new growth to me, nothing to worry about. It probably would of been great for getting some long stem roses off.
Thanks - I think you're right about the shoot. No, it's not a problem in Australia - and I guess that's one more reason to be thankful for biosecurity rules between the continents.
I am South African living in the UK.
I have also never heard or seen that in SA.
When you described the growth, I immediately thought that my mom taught me, if the growth comes out of the ground it's a "sucker"
But if the growth is on the rose at the bottom and it is always reddish that is a good new growth.
Probably not something in the southern hemisphere?
I find growing roses in a tiny garden in the UK more difficult than in South Africa.
And I always have to have a Peace because that is one of the first roses I knew, and ofcourse terrible black spot trap, very bad in the UK, but still get some beautiful roses and takes me back 60 years ago......
Thanks Anita. You're right - the concern about Rose Rosette is a North America thing, so those in the UK or SA don't have to pay it much mind. This was an own-root rose, so I'm going with it being just a strong basal break.
@@FraserValleyRoseFarm
I always watch your videos because they are interesting and you are so sincere. People are fortunate to be able to have your expertise.
Thanks so much for this, and for titling the video effectively. I know you don't do clickbait, so I immediately watched. Last year I thought one of my Julia Child roses might have RRD, but it was fine, and flourished this year. I'll be winterizing my roses here in Grand Rapids in about a month, meanwhile they're performing later than usual, perhaps because spring was so late this year. I'm buying a calendar, now, and thanks again!
Thanks for sharing your experience. "Wait and observe" worked out for you! Our roses are still putting on quite a show for late October too!
Thank you for your honest sincerity
Great video, thanks.
thanks for your honesty-- so you wont feel bad--- i purchased a rose from david austin directly, arguably a good nursery. with non curable virus and they confirmed diagnosis and were unable to send alternative as they are having to shut down their N american sales because of virus issues-- obrtained refund instead -- do not feel bad as it happens to the best of tghem
Thanks. I've had a few with mosaic come through with bare root from the US, and so I know the risk of virus can't be avoided completely. Anyway, I'm happy this one seems to have turned out okay.
eeks! Makes me nervous about the DA I added to my garden last spring. 🥺
i couldn't worry, if it hasn't shown up by now , you are most likely safe--- the other roses i bought directly from DA, at the same time, are all doing very well to say the least-- DA is a top notch company that cares and stands by their product if there are any problems for 5 years-- i probably should not have posted the Post and i am not negative about the comp;any or their many fine roses
Same here. One of my DA roses ordered from official website this spring showed signs of RRD recently. Other roses from the same order seem fine so far. Did you have to send pictures for a refund? I didn’t take any before dumping them.
Thank you very much for bringing forward information on rose rosette disease. With over forty roses on my property, I hope never to encounter this first hand. However it was the first time seeing Japanese beetles in my area as they are migrating north in Ontario so one never knows.
Never heard of it. Thanks for putting the info out there Jason.
My pleasure. Thanks for watching Debra!
Changing my mind I am cutting it down and digging out the roots. Dam.
Thank you for this information!
My pleasure!
Very informative - thank you.
Thanks for sharing Jason. I love the calendar. There's so much to learn and you are doing a fantastic job.
Thanks so much Annie.
I love your calm and informative approach to this situation. It's a disease I have never heard about, but your map included my section of New York. Thanks for being an advocate for roses and how to take care of them.
My pleasure. Thanks for watching Norine
I would not hesitate to buy from you because of your thoughtful transparency. Roses do not grow well here. I have not yet found the best location for them. Brightest blessings.
Stop letting this worry you Jason. Its written all over your face how much you are worried. 😁
I've had a lot of roses throw red growth. I have never heard of this disease but never had any problems to look for a solution. Great info
Thanks Mama J
Thanks, Jason. In the US, always contact your state university extension office with any suspected disease issues on roses or any other tree, plant, or flower before destroying or disposing. They are a wonderful, fully knowledgeable resource available to everyone, and they track possible disease epidemics before they become an issue.
Thanks Mr. Knittle. That's something I've heard about the US extension offices. Even here in Canada, there's pretty good support from CFIA and provincially supported plant labs - you just have to know how to access them.
Once again you teach me something new that I was unaware of. Thanks Jason.
My pleasure. Thanks for watching Dennis.
Thanks for your transparency and for the RRD info, did not know about it.
Very much my pleasure. Thanks for watching!
Wow thank you for sharing that information, that way you described the disease I believe that’s exactly what my knock out roses have.😢
Nuts, sorry to hear it Gloria.
Thank you for this info. I have around 36 rose bushes of different varieties. I live on the east coast of Virginia. I’ve seen by maps that we have a couple of cases of RRD in a neighboring city. It’s very concerning to me. I normally purchase my roses online from nurseries out west due to the nurseries in my area have started to carry only Knock Out roses. I’m fortunate that I’m the only one in our court, or surrounding area, that has roses.
Thanks Karen. We're kind of isolated around here too, but I do actually keep an eye on the wild roses in the woods near here (just in case I spot something!)
Thanks for the information Jason!
My pleasure!
Love your channel & many thanks for this excellent video about this serious problem. We are very lucky here in the west---except for the disaster that happened to Weeks a couple of years ago. The Rose Geek has a lecture by Dr. Mark Windham that seems to have most of the science that is known about rosette disease, some things to be aware of, & some reassuring info, too. Still, I plan to go out & nuke every single wild multiflora on my property with my handy dandy flamethrower (OK, it's just a propane torch, but flamethrower sounds so much cooler!). Thanks again, may your roses thrive.
Thank you for this video. I had witches broom last year , and was bested by it.
Sorry to hear it Jay!
I have 9 roses all except 4 are knock out roses. I have seen what I think is rose rosette on 1 knock out rose. I cut out the deformed piece then saw Jason's video. I am waiting until end of season and then get rid of the knock outs
I totally trust your Nusery stock. If I ever have what I think is a problem I will promptly bring it to your attention, so you can expertly diagnose ❤
Thanks Pozzee. And if I can't do it, I'll send it on to the plant lab!
A good video Sir, Rose Rosette Disease is very common here in Marshall and Madison County AL and in Maury Co. TN, where I have lived and raised roses all of my life, My specialties as a landscaper, my degree in collage was Botany, but it pays very poorly until you have a doctorate, were roses, pruning and boxwood. I have thrown out hundreds of roses from my garden, my mother's, she raised miniature roses for the florist trade in Nashville, and clients in Huntsville, I have found that the ones that caught it the most were descendants of the multiflora rose, an very invasive species here that fills the hedge rows and sunny edges of woods. A few others seem immune, Hybrid perpetuals and Rugoas except the ones that were bred back to Teas and Hybrid teas. One thing I have found is that if you catch it early enough and prune all the way off to the ground on an own root rose it MAY be salvageable. A very rare family rose was wiped out by an unseasonable freeze in late April of 18 F, the only known survivor was in Knoxville at my brother's wife's family home where it was some 30' across and one small branch had a single rosette with it. I dug it up as the house was selling and the lot was to be bulldozed and brought it here leaving the branch there in the brush pile. I took some 150 cuttings of all types, semi-hardwood, hardwood and Ts of semi off hard, about 10, 6' long, some in pots, most buried in the ground in trenches. Those that took, some 70 were raised and watched for 3 years, about 30% were infected, the rest have been clean for about 15 years, I started sharing them back to the family at about 5 years and all are still clean. I would only recommend this if it unobtainable elsewhere. I do have a New Dawn that got it, I took it down below the ground and it has come back clean but that was 3 years ago and I am still watching it closely, it is in an isolated space so probably safe as far from the other roses as it is.
Sorry to hear it Jefferson. It's such a shame to see older rose collections stricken by RRD.
No plant for testing, no idea what the problem is.
Thanks Marla. The customer still has one of the two "suspect" roses in hand, so if it did show symptoms (beyond just red new growth) I'd be able to get it to the plant lab. I suspect it won't be necessary.
Unfortunately it is very common here in the mid-Atlantic; I had to destroy a lovely 'Prosperity' bush because of it, and Rosa multiflora is all over the place here so you have to relentless it destroying it when it pops up as it inevitably will.
Bravo 👏
My David Austin has it one one bizarre stem mass of thorns and red colour on my Danahue.😢
Hi Jason, I retired a year ago and built a greenhouse with a mist system and a shade house with 70% shade cloth. Thanks to my 3 Gurus, Savvy dirt farmer, Mike Kincaid and yourself, I have had great success with cuttings in course sand or fine perlite. Hear in Melbourne Australia we only get about 5, 0 deg C nights a year. Zone 9 or 10 I believe. Anyway enough rambling. Keep up your great work, 😄my man.
I seriously thought I had a case this year but after waiting a month of so I don’t believe it was.
This struck my rose garden in Indiana. I had about thirty varieties and have lost over half. They floribundas except for the icebergs are all gone. The old school double delights and mr Lincolns. are doing fine. The sixtys teas are doing good. also it is the roses that I have planted in the last ten years catching it.
Thanks Glenn. Sorry it hit your garden so hard! And Iceberg for the win again!
hi Jason. I love your channel and have learned so much from you and trust your very clear and concise science-based advice. I have been following your channel for over a year now and you are the first place I go to for rose knowledge. But also I’ve really found your soil advice extremely helpful. I also garden in heavy clay in Ireland. Thank you for your informative channel. This rose rosette issue is very interesting and something I didn’t know about. I’m sorry you received that complaint. I wish the customer had verified the case with you so you could reassure yourself about your stock or assessed the risk if any. As usual, this video was very helpful and thank you again. Please keep making your excellent videos that help us learning gardeners!
Thanks Ronan. It all turned out well - the customer was a good sport about me sharing her feedback, and I provided a replacement rose last week. I appreciate the encouragement and feedback!
A few years ago my 3 knockout roses near each other got rosette disease. At first I did nothing because it looked like normal new growth on roses. They developed 3 confirmed symptoms so they were removed. Pleasantly, my Frau Dagmar Hastrup Rugosa near them was unaffected. In addition, I have a Bonica in another area that was not affected. I have since planted a single Knockout Rose bush on the opposite side of my property and all is well so far.
Thanks Donna. I'm so happy to hear your timely action saved the other nearby roses!
I bought a rose from a popular grower last year. This year it started out beautiful. Then I noticed the one long red cane with the twisty leaves on the end. I cut it off thinking it was a fluke. Then the flowers started growing smaller with missing pedals and a few more red thorny branches popped up. I dug it out hoping it didn't affect my other roses. So far so good. Of course I am no expert, but I am pretty sure it was rrd. It looked like every picture I see out there. The thorns especially were what convinced me as the rose didn't have many except tons on the red branches.
I didn't even think it could have been infected already. I hope the other one is okay! ( I bought 2 of the same)
Thanks for sharing your experience. I don't know if it's the same in other jurisdictions, but here in BC there's a government funded plant pathology lab - and any local nursery can access their services for a nominal fee. It sounds like your rose had more than one of the known symptoms - but it definitely would be nice to know for certain.
It sounds like this was a case of mistaken identity. You handled it well.
Thanks. And to their credit, the customer was cautious (maybe overly so to some degree), polite and constructive in their feedback!
@@FraserValleyRoseFarm Glad she was honest. No one needs that kind of stress. Especially a good business as yours, Jason.
It was an honest mistake on her part.
You are so kind to care about your customers.
Also you look thin, take care of yourself.Debbie from Texas
Thanks Debbie!
We had one DA Rose that we thought had the RRD but gave it the benefit of the doubt. Will keep observing.
Good call. I like the part of the "What to Look For" page on roserosette.org where they acknowledge that there are look-alike symptoms with other causes, and "therefore, it is important to check for combinations of RRD symptoms over time." It's good advice, and I'm glad you're being cautious.
@@FraserValleyRoseFarm Great suggestion. Will look into that. Thank you
Very cool video. First time I've heard about this. Is it a concern? A bit. I grow mainly Texas Native Roses here and they are tougher than any variety that I've seen.
Something that I was told in trying to diagnose RRD symptoms is, if you take a picture in black and white and you can't tell anything looking weird then it isn't RRD.
I also wanted to point out that the people who make up the map of the spread, they just mark anywhere that there is a report. I went through all of the reports in my home state, and every single picture was of healthy red/purple new growth. So unfortunately, while maps are a good idea to give a heads up, if you can see what was reported, then do it. It may just be normal growth.
To note, when I reached out to the website that was hosting the map, I got a "we reviewed the pictures and agree that this is normal growth." So unless they are alerted to it, people making maps aren't confirming before marking as present.
Thanks for those insights!
I was near certain, one of my DA roses had RRD, so I contacted my local extension and found out I was wrong, thankfully.
Lots of people post pictures in garden groups asking for opinions, and unfortunately lots of individuals give wrong information/ diagnosis regarding RRD. As you stated, It's imperative to always contact a professional regarding your roses if RRD is suspected.
Thanks for sharing your experience with this Amanda! It's such an easy one to get wrong, so I'm glad you took the time to get it right!
I suggest to include a small pamphlet with example pictures of RRD and healthy new growth with each order, perhaps by email. It would educate buyers.
Thanks!
When i first bought my Foolproof guide to growing roses some 20 years ago, i found out about RRD. The book only covered the everything concisely but the picture shown looked a lot like what one of my rose plant was suffering. I loved that rose and i only had one pot. I gritted my teeth and simply disposed all the infected canes. I was in denial. But weeks later the it began show healthy new growth and i never seen any RRD-like symptoms on the rose or any that was nearby.
That's really interesting. There are a few look-alike health problems (including nutrient deficiencies!), so I thought it was good advice on roserosette.org when they say "Therefore, it is important to check for combinations of RRD symptoms over time." In your case, a clean bill of health over 20 years seems to back up that advice!
We had small cases of RRD from plants brought across state lines, those were destroyed and no further cases were found. So we really don't have RRD, but I had a serious scare this summer. A normally low thorn rose sent up a huge red, thorny cane with weird looking leaves. Knowing we don't have RRD, I waited and found out that our unsually warm weather had caused it and the leaves unfurled nicely.
Phew... I'm glad you dodged that scare!
I purchased 5 knockout roses from Costco years ago and they were doing great until a 4-5 years ago. Three out of five had this and we got rid of them. The two that are left (they are all planted next to each other). My neighbor's roses had this too and she got rid of them as well but I was pretty sad to see them go.
That's really frustrating! I'm glad you were able to save at least a couple.
Wow, I didn't even know about this! Ya most of new growth in roses is red. I will not worry about it! I am just thinking out loud for me, what would I do so everyone do your due diligence! Thanks a lot! So sorry Jason that you had to go through this....so scary!, I am praying that it was just an over reaction from that customer and it's unfortunate that threw away the rose so fast. God bless!🤗💞
Thanks Cami. So far it looks like the other "suspect" rose is developing normally, and that this was just a overly quick reaction.
@@FraserValleyRoseFarm Yes I believe so too!
Hello Jason, I am president of the Humboldt Co. Rose Society in extreme northern coastal California. I have not yet seen any roses in our area with RRD. We have many consulting rosarians, which I am one, in our district who are well aware of this disease. I agree with another comment that round-up damage can appear to be RRD. This late in the growing season I believe it would be prudent to cut the stem as though a winter prune and wait to see what it looks like next spring. Love your channel.
Thanks Jack. I pinned that other comment to the top so hopefully everyone will see. It's a good point about misdiagnosis from herbicide damage. Heck, I've seen twisted and deformed foliage and flowers because of powdery mildew and thrips damage too! So it's definitely a matter of close observation to make sure you're treating the right problem.
@@FraserValleyRoseFarm 100% agree
ah sorry, i previously responded before listening to the end of your video where you say it was highly unlikely on your nursery
No worries - and thanks for your feedback!
I also was warned about RRD and panicked but I didn’t destroy my rose plants and sure enough as you talked about there was no RRD just a normal plant growth I had not paid attention to before.
Thanks Troy. That must have been a bit of a scare, but I'm happy you kept your head.
In NE USA I have RRD on my red Knock Out roses. So far it is on one pink but never on the white peach or yellow. I have been cutting when the short crinkled growth just starts. New info says cut the entire branch to its origin low on the plant. The bomb proof Easy Elegance Calypso now has it after years of recommending it to customers.
From what I've heard, once a plant is infected, the virus is in the entire plant and root system. You may be able to snip back the most symptomatic stems, but the only sure way to eliminate is to remove the entire rose I think.
@@FraserValleyRoseFarm The original bed is totally cut back and we will finish digging it out next spring. We still want it to be a rose bed. I drive by some businesses and homes that have them and they just get better each year.
i thought id got it on my james galway, classic foliage pattern, only to discover id been scorching my plants by zapping aphids with dilute washing up liquid and got an unusually sunny spell that broke through what had been a cloudy day
Thanks for the reminder - always retrace your activities and recent conditions in your garden before assuming something worse!
Rose rosette looks so strange, that it really can't be mistaken for anything else. However someone has to be familiar with the normal red growth of roses before knowing the difference. Something else to consider, so many people have knockout roses in their landscapes. Knockouts seem to be having this problem more than other roses, and they can easily travel to a neighboring property. It was really sad when I had to get rid of mine.
I don't know if you have something similar on Canada, but in the US, you can send samples to the local extension offices
Thanks Nurse Lucy - in BC the plant lab will test (at a nominal fee) for nursery/greenhouse growers, but not for individual gardeners, so it's best to get back in touch with the supplier (which this customer was good enough to do!)
This is a concerning topic, but definitely very important for discussion and awareness.
All of my roses are box store purchases and that means out of state because there are no local rose suppliers here in Hawaii.
Due to the volume of plants bought and sold with little regard for diseas, infestation, or contamination, not to mention a severe lack of training in these types of stores, anything literally is possible.
The worst part is the, slow to act for fear of responsibility, attitude.
I find it very troubling how generic most of the described symptoms typically are because they are the natural characteristics of most roses. So far I have not seen or heard of any problems here, but I know one person who brought some roses back from New York (I think) that had developed withering foliage and shrinking stems, but it turned out to be travel shock because she put them in her checked baggage. The roses were fine once they were in the ground and had some time to adjust.
While there is no guarantee that these types of problems won't find their way into our yards and properties, the best defense is careful observation and not acting too quickly.
It's always worrisome that the disease or the mites could spread to a new area like Hawaii. On the bright side, I think the growers are much more vigilant about the problem than they used to be. I used to hear horror stories about large-scale infections at the grower level (and I worry about that complacency you mentioned! Just cut them back and ship!). I hope that's not the case any more. One comfort to home growers may be this: just finding some unconfirmed symptoms of RRD on a rose doesn't mean that your other roses are immediately at risk. If it ends up being a look-alike symptom, obviously, that's no big deal - but even if it ends up being confirmed, it's the presence of the vector mites that's of concern for the spread. They're a lot easier to confirm than the disease itself. So in general, you have a bit of time to see how the symptoms play out, so long as there are no mites detected. The rose rosette info site I linked advises the "watch for combinations of symptoms over time" approach.
@@FraserValleyRoseFarm The very reason we have such a big problem in some areas is simply selfishness and greed in the large grower area.
Unfortunately there is still a great deal of cut and ship nonsense happening in certain areas where quality control is lacking.
However, information like this is the absolute best way to deal with the situation as a whole because consumers are much more educated these days thanks to channels like yourself and others getting the word out.
Knowing how to identify different problems and solutions to remedy those problems has really transformed the plant industry over the years.
Supplier reputation has been severely affected by their own carelessness causing drastic changes in inspection and consumer awareness, creating wary buyers and eventually better products as a result.
The RRD situation is directly correlated with the actions and behavior of large growers and suppliers not addressing the issue early on.
The good news is people are becoming more careful and certainly much more involved in overall care for their plants which increases the level of information being shared.
I think learning more about how to more effectively address the mites and other possible spreaders as well as better understanding about RRD itself are really the key targets, but that is an enormous task.
Developing disease resistant roses is certainly a temporary solution, but I wonder if that isn't actually part of the core problem.
When scientists discovered antibiotics the world was forever changed creating a complete transformation of health worldwide.
Unfortunately with this new way of treating people they did not know about the adverse affects of over use and eventual noneffectivity.
Of course now the cautions of over usage are everywhere.
Perhaps some of the disease resistant engineering has actually created a similar scenario in plants much like the antibiotics in people.🤔
We know that a sterile environment actually creates weaker immunity to the natural environment around us. If we don't experience a certain amount of exposure to that environment we become vulnerable to everything in it.
Natural immunity is critical to survival.
Knowing what to look for is extremely helpful for sure, but knowing what the root causes are, not just symptoms, is the only way to finding proper solutions.
Cleanliness is still the number one place to start when introducing new plants into a space.
Always careful inspect each plant before buying them and then again when you get them home in a separate area away from all other plants.
I keep all new plants separated for 2 months to watch them grow and see what might develop. I look for possible disease, pest hatchings or things of concern. Once I know the new plants are safe, then they find a place in their new neighborhood.
These practices use to be common advice for all new plants, but somehow the instant beautiful landscape became normal, putting unearned trust in suppliers and new growers trying to keep up with demand.
Taking those extra precautions can make all the difference.
I am not typically a pessimistic person, but knowing how all the different industries are struggling to survive means keeping a much closer eye on things because they probably are not.
We all want to enjoy the beauty of our newest additions, but sometimes it truly is worth the wait.😁😉🤙
The dark red shoots from the base of my plants are healthy new canes. I am just learning of this rose rosette disease. I hope we don't start seeing this here in the PNW.
You bet Mary. I've been keeping an eye on the FB groups, and it seems (from my unscientific sample) that misdiagnosis it killing as many plants as the disease itself. But I really hope it something the researchers and industry can get a handle on before it becomes a widespread problem locally.
The other day I saw something on Reddit where someone asked whether their rose had RRD or it was just new growth. Many people helpfully pointed out that it wasn't in fact a rose.
That's an awesome new twist!
Could you please do a video on the best or your favorite roses for pollinators, I love your videos :)
Thanks for the idea. I'll add it to the video list. In the meantime, if you have the room, 'Darlow's Enigma' is probably going to take top prize.
Darlow's Enigma is awesome, as well as Mutabilis, Lyda Rose, New Face, Doctor Robert Korns, Ghislaine de Feligonde, and any cluster blooming rose with less petals. I can always hear bee buzzing around these roses.
Jason, I subscribed to you primarily because you are a Canadian grower too... Please, when you put up maps to demonstrate a point, post the Canadian map too.
Thanks. I would have been happy to, but I couldn't find a similarly detailed map covering Canada. There's something posted on CABI www.cabi.org/isc/datasheet/47834#toDistributionMaps but it's pretty broad
@@FraserValleyRoseFarm I can see why you didn't choose to go with this map...
I just got into roses this year and was very concerned when new growth was coming in bright red... I did some research and realized it was normal and RRD wasn't an issue on the south Island. Everything turned out fine but there was one sleepless night that I was worried I would have to burn my precious rose. 😂
I'm glad you took your time!
My worst nightmare….I found that mites proliferate during hot dry summers and I relied on acephate (not sorry) and essential oil emulsions to proof them and ward them off with the scents. The acephate is systemic and will last for nearly two months. The customer must have taken good care of the rose since it’s putting forth healthy shoots. I was initially scared too after buying an own root rose when it suddenly grew a thick tall single stem, only for it to become a full healthy stem producing larger roses. When a rose is grown in a small container, it is bound by the pot size and will put out stems that are proportioned according to the pot, but when given larger pots, it upgrades with thicker stems to match the new size.(My theory 😂)
There are systemic miticides that you can use. I hate to recommend them, but still…
Thanks Declan. It kind of looks like this one could have been a false alarm, but every rose nursery should be careful. I'm with you - miticides wouldn't be my first choice, but I'm glad they're available just in case.
Jason please don't worry yourself about this? Literally anyone could say this and it could be anything....this is gardening. I very much doubt its Rose Rosette and the fact they just threw it out, to me, looks suspicious, without pictures or evidence. You re doing a wonderful job and your passion for roses is infectious. Keep up the great work and look after yourself.
Thanks Steph. I'm not worried, per se... but it's a good reminder to be watchful of the disease situation. I don't think Rose Rosette is spreading in our area, but that doesn't mean it never will. The customer and I are all good - they did the right thing to report their concern to me, and remained polite and constructive throughout. They may have been to quick to dispose of the rose (live and learn!) but I really can't blame them for being concerned by some of the information going around about RRD. Anyway, it's a good way to introduce a conversation worth having.
@@FraserValleyRoseFarm absolutely Jason. The thing is...this conversation would have had to have been approached at some point anyway. I just can't imagine the stress you ve been through though. Thankyou for informing us about this. As a gardener we re always learning. I find your videos to be informative and wonderful in witnessing someone with their passion. I adore roses. I only wish I could purchase from u here in Scotland. I thank you again Jason and wish you the very best moving forward with your beautiful farm.
I am a Garden professional in North Carolina, USA. I have several clients in a certain sub division and I've noticed MANY roses in this particular sub division have HORRIBLE cases of Rose Rosette Disease. I'm afraid to even plant roses in my clients gardens because of this. What do you recommend? Have you heard if its illegal to not dispose of plants with these types of serious diseases? Thank you Jason. Another very informative video.
Hi Deborah. I'm not sure about the legal end of it at all, but I wouldn't see the benefit to anyone to keeping the diseased plants (and therefore increasing the risk of spread) since it's not curable. But educating people about it may be another matter. I know they're working on new resistant varieties, but until there's major progress in that direction, I suppose the only tools are vigilance to spot the signs & remove the infected, both in the garden and in nearby wild multiflora populations.
@FraserValleyRoseFarm Thank you for your response Jason!!!
The other thing that's paramount in the discussion is getting info from well advised, well versed people. On any forum, There are those who run off at the mouth but have no real horticultural background upon which to draw conclusions. Beware.
Thanks Darryl - a good bit of advice. I'd take an actual plant testing lab as the best solution, followed maybe by a university/agricultural extension service or a consulting rosarian from the local rose society. Posting pics on a facebook group means you'll have to wade through a range of opinions.
I’ve been hearing about a movement to eliminate multiflora when found at least here in Texas since it’s invasive anyway. Do you think this includes roses grafted to multiflora root stock?
The rootstock suckers have definitely contributed to "escapees" in the past, but I'm not sure I'd go so far as to target the grafted roses - just to choose own-root (or grafted onto something other than multiflora) in the future.
Hey Jason, I have found 4 strange looking roses we planted 2 years ago. Seems what type of soil makes them grow very differently. Pulled them,cut back ,and potted to see if they will come back. Question, have you every dealt with ground bees in potted plants? Watering cryple myrtles an they started.coming out. Not sure yet which pot. How would you address this problem? Do you use any thing in keeping ants ect, out of pots? Thanks
Thanks Dean. I've definitely dealt with ants (hard to keep them out, really, but if they become a problem I'll use a borax bait trap). I haven't ever dealt with bees though! Interesting. If it becomes necessary to move them along, I'd probably try to disturb them (to get them out of the soil) and then cover with plastic temporarily to force them to nest elsewhere.
I say don't be trigger happy about dumping any plant
plants generally take a step back after planting before it goes forward and plants planted in autumn winter time have a tendency to do this first the plant has to get used of your area soil heat cold etc and no harm in that
so first most important step is
leave your plant in it pot a day or two before planting
Water do not use liquid feed or any fertiliser more young plants are burned with kindness and taught to be under attack by some fungus or insects when they have fertiliser burn
Don't go jumping to the disease section of planting
Best thing you can do is for any plant is soil preparation put the money into the soil first what type is your soil you zone rite plant right place
Plants that are well looked after are lot less lightly to get attached And rember if you want good insects into you garden like lady bird frogs etc bring in the bad insects the more food for predators more predators will come into your garden
God bless the rose
Thanks Patrick. Totally the right approach to focus on the basics - decent soil, reasonable sun, consistent watering, mixed plantings. With a healthy plant a few pests aren't as big a concern.
i have mistaken new growth for disease. take a breath and do lots of research!
Good advice!
Breeding resistant roses takes time. Have there been any major rose diseases in the past where they found a cure, with like a foliar spray or a root drench?
I think the second best step is to make sure your roses don't get mites, but that isn't fool proof. What about healing the mites? 🙃
Thanks y0nd3r. Those kinds of chemical treatments might be less likely to be developed for RRD because it's a virus rather than a fungal or bacterial pathogen. The vector mites are one link they can tackle through miticides and/or predators. It also could make sense (but maybe easier said than done) to go after the "reservoir" of infected Rosa multiflora the disease seems to be travelling with. It sounds like the breeding program has something like 20+ resistant varieties tested, but you're right; that's still a ways from offering a "critical mass" of commercially successful resistant varieties into the North American rose market.
I am moderately concerned about Rose Rosette disease in my roses.
Thanks Dolly.
I've had RRD on a couple roses. I've never bought a rose from a nursery. (I live in yNJ) Your customer was right to let you know so you can check your stock. And, as you say, is your customer sure?
You bet - I'm quite glad the customer kept me in the loop, and it reminds me to be watchful not only of my stock but for symptoms on wild roses nearby.
The worst part about having such a Business...the Customers! LOL
Thanks - I don't so much mind the customer end of it. At least we have some interests in common to talk about! Then there are little moments like this that you have to deal with, but it all turned out okay in the end.
I can honestly say that in the 25 years I've been growing roses, not once have I come across rose rosette disease. Perhaps the deep winter freezes of eastern Canada keeps the rosette mites at bay?? Your map shows eastern USA but not eastern Canada where deep freeze occurs 6 months out of the year. The last thing rosarians need is a horrible rosette mite on top of the Japanese and American rose chafer beetle infestations that trouble Ontario and parts of eastern Canada.
It also has something to do with the distribution of wild multiflora roses, which are susceptible and make good hosts for the mites. I've heard reports that it's shown up a little in southern Ontario, but let's hope it remains rare.
@@FraserValleyRoseFarm Good to know! I've seen a beautiful multiflora growing wild at a friend's garden in the south-eastern Georgian Bay region of Ontario (considered south-central) but seen no RRD in zone 5. Southern Ontario produces peaches and grapes; a zone closer in climate to British Columbia.
I always notice that very new young growth on a rose is not green it is a reddish colour.
Yes, definitely. Some people panic (as did this customer) when they see the striking new growth, but I'm happy to say it was a false alarm.
@@FraserValleyRoseFarm so many people do live in fear unfortunately. No journalist, politician or doctor could ever make me afraid of you can guess what and now the latest news I saw on Facebook media was them trying to make us afraid of a storm on its way here. I shared a picture of new growth on your Facebook.
How many roses you have grown and sold are healthy and happy 🌹😊?
How many kids have they had, and joyful rose kids🌹😊?
How much fun, joy, beauty, pure life force experiences have these brought to mama Gaia, you personally, other growers, onlookers, animals, bugs, etc 🌹😊?
How about trying mixing some natural herbal plants around roses, e.g. mugwort? Mother nature has tested many times, and she's a bit naughty too, hiding solution to one plant in another plant, or animal, or minerals. Sometimes a rebalanced overall environment help everything thrive.
Did ANY of YOUR roses develop this? If none of your roses have then my guess it might be in that customer’s garden. Love your channel
No, my stock is still entirely free of the disease - and it turned out to be just fresh red growth misinterpreted.
@@FraserValleyRoseFarm sad that they were so hasty.
I have questions.
Should the questionable plant be isolated? Mites tend to spread through an area of the same plants rapidly under the right conditions.
Can a Miticide and a hard prune remove the mites and therefore the disease from the plant, or is it a once its done there is no going back type deal? I know you're an organic producer but some of us are not so morally inclined.
These are just random thoughts. I have found information from Aus govt about the disease, but not any indication it has been found here as yet.
Good questions Brad. I've been told that once a plant is infected there's no practical way to eradicate the virus in a mature plant. The mites are just the vector, so eliminating/controlling the mites might stop the spread but it won't cure already infected plants. The mites are also wind-borne, so just managing the mites and plants in close proximity doesn't solve the whole problem. This is why having that wild reservoir of susceptible R. multiflora to "fill the gaps" seems to match nicely with the distribution of the disease. Smarter guys & gals than me will probably find the right balance between a) resistant rose varieties, b) managing mites, and c) identifying & eliminating infected rose populations. Happily, I think you're right that Australia doesn't have the mites or the disease (nor, I think, the wild spread of invasive roses) - and they seem to be pretty on top of biosecurity policies, so let's hope it stays that way!
Goodness, I wish you would have offered some expert advise on what to do next. I know I had RRD. Someone told me to wait it out, and I ended up leveling my whole garden because everything around it started shriveling up. Finally dug up all six three year old Knock out roses, and now someone is telling me I can’t plant roses for three years. I’m so confused.
Thanks. I can't include everything in the videos (for the sake of length) but I'm always quite happy to offer advice in the comments. I think the issue with replanting roses in the same area is that they could "root graft" with the remaining roots of the diseased roses. If you want to get fresh roses in another part of the garden, it should be alright. Did you ever get a handle on where the disease spread from? Sometimes it's mite infested wild roses in the area.
@@FraserValleyRoseFarm thank you for your quick reply. I understand. I don’t know where they came from. From what someone said me, a few other knock-out roses had it in the neighborhood. I’m grateful it didn’t reach my main show of roses in the backyard, but I’m disappointed I can’t plant new roses in the front. I filled up the soil and put down new amended soil, but I’m guessing that not good enough. Our neighbors roses weren’t effected however, so I wonder if it came from the Nursery. Or just a random infection? It puzzles me.
Do birds like roses Jason? I have always wondered
They enjoy the branches/shelter of roses (esp. during winter I see small birds flitting about in my larger shrubs) and of course the rose hips too.
@@FraserValleyRoseFarm thanks a ton for the feedback Jason!
I believe knockouts are more susceptible to RRD so will never buy another. I had 2 and one must have come with it and spread to 4 others, one not being a knockout. Have not planted another rose in that area.
That's a tough break Jo! I've heard the same thing about Knockouts, but I wondered if it was just a numbers thing: they're so widely and densely planted that they were bound to come up with higher total infections.
@@FraserValleyRoseFarm could be!
Hello Jason l hope you get this message I'm just trying to find out if you know if l can mix 20 mule team borax with water to put in a spay bottle to kill ants . I like your video about the potted plant and the trap you made . If you don't reply that's OK I wish you all the best !
No, I don't think it would be very effective to spray with a solution of water and borax. It's not a contact killer, and works when they eat the solution - so the bait method it both safer and more effective.
