- If you notice chewing damage on your rose, you may wonder what's eating your plant? Let's have a look at those holes in rose leaves. Careful inspection may reveal the culprit, and in this video I'll discuss some of the usual suspects: deer, rabbit, leafcutter bees, rose slug sawfly larvae, slugs & snails, Japanese Beetle, Rose Chafer and Rose budworm.
If you find these videos useful, there are a few little things you can do to help me out:

It’s like you read my mind. I found little holes in the leaves on my roses, yesterday, and this morning, this video pops up!
Thank you again, you are so informative and helpful. I will be taking a much closer look at those leaves, ASAP.
What a great video on roses!! I've searched through so many on CZcams and yours is straight to the point and very informative 👌 I will def be subscribing!
Jason you’re absolutely the best.
Thank you Jason. Very helpful indeed
Fantastic information, thanks for sharing 👍❤️😊
Great video graphics. Thanks for making such an informative and pleasant to watch video.
This was really helpful. Thank you for this simple explanation of different pests and how to fight them!
Are you gonna' learn about them and then fight them right after?
Thank you very much for the explanation.
We have wild rabbits (Hare). My first beautiful red rose grew and bloomed all summer. The next spring the bark was chewed down to the roots. It did not survive. But I caged my blueberry plant and it did great. The roses taught me well. RIP.
Thank you so much!!! I’m in central Texas and had no idea what I had on my young rose bush. Now I know (saw flies).
Thank you so much. This was so helpful !
Northern Ireland...we have vine weevils and their larvae 😭 and the sawfly thing you mentioned, only just thought it was a caterpillar! Great information as always 😊
Always enjoy your video's
Thanks so much! You are so helpful !
Amazing vid as always, thank you ;)
I can’t believe I came across this video just now! Just yesterday I noticed damage on my rose leaves which now I know is from a leaf cutter bee thanks to you. Your videos are so thorough with great information! Thank you so much
Very much my pleasure Leah
Ditto… yesterday😀
& now again this year! Grrr.
Thank you so much for these informations. 👍🏻👍🏻👍🏻
So helpful, even for me having a garden with roses in France, Europe.
Nice information, thanks.
Very helpful. Thank you very much
Thanks for this video, Jason. I was able to finally identify the reason for the “skeletonization” of my David Austins! I did a bit of looking and squishing, and I’m hopeful that will handle it. I’ve purposefully planted lots of Veronica to host ladybugs but I’m not sure what other predators I might need to balance out my micro environment. Many thanks for your helpful advice.
Came across your video. Been struggling to figure out WHAT IS EATING MY ROSEBUSES! ROSE SLUGS. thank you so much will try this! 3 years of eating ugh
Thanks Jason
Had this issue here in the UK, those exact round holes at the edges of the leaves. Thank you for the video
Og Oh are you there their spokesperson or something?
thank you, very helpful.
Please allow the bee to eat the leaves of your roses it doesn’t affect the plant and the bees are very important for the ecosystem
The plant can't thrive without its leaves.
Normally that is true. But every once in a while leaf cutter bees will over graze on a rose. Deploying a cheesecloth over your rose is a good way to deter leaf cutter bees without harming them.
Jason this is another great video and very timely for me. I was just wondering today what those half-way leaf damages are… rose slug 😩😩😩
Thank very much, so much knowledge, which I appreciate. I have deer, which I use electric fencing. Janpenese beetles, which I'll watch your video and leaf footed bugs. Leaf footed bugs are eliminated with a bug zapper in the early morning.
So informative. I was ready to dig out my beautiful Abraham Lincoln Rose bush but now I have the tools to fight these pests and ran out and picked up some insecticidal soap. Thanks for the schooling
Thank you for having such a great video on this, the rose sawfly is exactly what I have here
Glad to have helped you narrow it down!
I’m in the UK & am apparently suffering from - or my roses are rather - what I think look like leaf cutter bees… not sure if we get Sawflies in this part of the world but as soon as it’s light enough I’m off on the hunt for some … frass!?? Thanks so much for your fantastic videos - have found them a massive help & really educational as a total newbie to growing roses 🌹
Black spot is a real thorn in my side
hmmm I needed this vid. leaf cutting bee is what I have
Something is eating all the buds and almost completely defoliated - thinking grasshoppers as we have 5 acres and I see them in the grasses but don’t find them in the courtyard loosing 75 roses please help I am in Texas - very hot here
thanks for another great video; Down Under our roses are just breaking dormancy so we soon will have all these pests to look out for
That's exciting - my favorite time of year. Have a great season!
Thank you
Thank you so very much. Bud worms are destroying my Geraniums, so will give BTK a go. Very informative 👍🏻
I used to catch rose slugs in action but didnt know what they are. I would then feed them to my golden fishes (lol) and they like eating it
I have the bud worm, first time my rose ever had this, I just got done last 2 years with Japanese beetle. At this time using Neem oil, and squishing them. Thank you for information.
I just let Malora Malota sit where I wish I was.
So far the sun has been that’s eating my plants this year.
I was puzzled, until I watched a little bee cutting into the leaves. Leaf cutter bees are sweet little things. It didn't cause any lasting damage, unlike Japanese beetles.
Thank you for this video. My rose buster were so healthy and the bloom was beautiful. in May 2023. By June I have no bloom and my rose bush leaves had holes and barely any leaves. It looks bare. I followed your advice and started the spray treatment under my leaves. My local plant nursery recommend an organic fertilizer to enhance new growth. Please let me know if there are any other steps I should take. It would be great if I could get my rose bush healthy again.
I live in 6a and now you’ve made me almost certain I have a sawfly issue. Thank you so much
thank you Jason. I enjoy your videos and have had some success with roses. I live in US zone 7 and summer in zone 5 in New England. I brought some potted roses to zone 5 this summer and had sawfly and most recently what I think was katydid trying to eat bud. Would you consider doing a video about putting potted roses in a sheltered location for winter in a cold climate? I successfully overwintered in pots in zone 7 but doubt it will work here. I've heard of people keeping in garage but not sure if it would need sunlight through a window. Sadly I don't have a heated greenhouse. Thank you.
Thanks JP. I'll add it to my list. I suspect you can overwinter in a pot even in zone 5 - once the roses are dormant, they don't require much light, just reasonable air circulation and occasional checking for moisture.
Thank you jason.. I hope you dont mind that i share your vids in fb groups when people ask about roses
Thanks Hazim - sharing is wonderful! Helps my channel, and hopefully helps your group members as well
Snails, grasshoppers, leaf cutter bees, and caterpillars all love to eat the foliage on rose bushes.
Thank you for another great video! 👏🏻👏🏻👏🏻
What can I do about spider mites? My garden is suffering this year 😞
Thanks Lili. Here's a closer look at the pest: czcams.com/video/mI5zowOac6I/video.html When I see a severe infestation, I strip the worst of the leaves. Beneficial mites are an option - some sprays can be effective, but the webbing makes it tricky to get good coverage onto the pests themselves.
It's so funny because I always come back to this video thinking that some mysterious exotic pest as been chomping at my rose leaves and inevitably just come to the conclusion it was a slug
I have the sawfly larva. But I’m hesitant to spray my bushes because I noticed the wasps where eating them, just not fast enough.
Seems like there may be more damage coming since I've seen so much promotion around getting leaf cutter bee kits for your garden. I had never heard of them before but suddenly you can buy leafcutter bees, houses for the bees, etc. in various garden and home stores.

Thanks for the video!
Hardy hibiscus (Hibiscus syriacus 'Blue Bird')
Potential video idea: identifying thrips, thrip damage, and the solution for their removal. I just checked all my garden channels(you, epic gardening, Charles dowding, etc) and I can’t find any info on them from the people I trust and want to hear it from. Would love to hear your thoughts on thrips.
Thanks, I'll add it to the list.
I might have more than one problem, but I for sure have rose chafers eating on the plants. I crushed one with a needle nose pliers. I didn't know what it was until I had seen the pic you posted. I had no idea the problems I could end up with when I decided to plant these. I was going to plant 10 more, but now I'm thinking something else.
Sorry to hear it Robert. They're such a pain!
Great video, so much useful info. Thank you. Can you help me with What is happening to my new rose buds, its a climbing rose? It looks like someone cut them off! I live in UK , the plant is very heathly I have sprayed for black spot & whiteflies/Aphids so all good there, one day lots of buds and then all gone? Very disappointing as didn't have this happen last year. Advice
appreciated.
Wildlife feeding damage would be my first guess: here I'd suspect rabbits, deer, squirrels.
I often find those leaf cutter bees have taken a chunk out of a number of my plant leaves, but I like bees of all types, and they are just making a living. Not long ago I found a death's head hawk moth caterpillar on a honey suckle bush. It had eaten every leaf on the bush, the bush about 2ft cubed. I couldn't believe the size of the caterpillar, about the length of a pencil and three times as thick. I decided to put it on another bush, but there was no more damage, guess he had his fill already. Then the honey suckle that had been eaten, grew back better than all the others anyway. Funny how things work out sometimes.
Thanks Gary. There's a lot of pests I more or less tolerate, but with the leaf-cutter bees I actually kinda cheer them on! Interesting tidy holes in the leaves and no lasting damage, and they've got a job to do! That's one massive caterpillar - explains the appetite.
@@FraserValleyRoseFarm Funny, because as the plant lost leaves, I checked under the leaves for caterpillars, but found nothing. Then, I saw it stretched out on a branch, with it's light green and yellow camouflage, and I thought, no way! Had to look him up on the internet. :)
This is great info Jason. I'm confused because I live in NY. zone 5 but in your community message you are in Canada zone 8. How is there a place in Canada that gets that warm?
Thanks Dennis. It's because we're in a Pacific coastal area - just three hours north of Seattle, so our climate extremes are moderated by being close to the ocean. Similar to the reason that Buffalo is zone 6 - proximity to the great lakes.
Saw fly it is ..thank you
oops may be the bud worm as they are concentrated on the buds
That looks like leaf cutter bees have been visiting
Hi Jason, my roses are being chewed to the stems. In just 48 hours there wont be a leaf left! Ive sprayed for Japanese Beetles, but its not working. What could it be?? Its horrid looking not to mention all the time I have put into these beautiful plants. Whatever it is, it works really fast!
Mine have little green caterpillars
Thank you Jason. I pretty sure that snails are my problem. I'm in Tuscany. What do you about snails?
There's a slug bait I use that is OMRI (organic) listed, and won't harm pets, birds or other wildlife. It's marketed here as "Sluggo" - the active ingredient is ferric phosphate. I've previously had good success with yeast traps.
Deer is my #1 pest then Japanese beetles and them little green worm. I spray with liquid fence every 2-3 weeks for deer. Let me know if there is a better product out there to use. For the JB I placed a couple of the beetle traps around and only found one on my roses this year. The rest went to the bags and died there. I caught hundreds of them nasty beetles inside. They left my garden alone too. That hormone that’s in the bag seems to work great!
Can you not trap and roast those deers?
Jason hi we live in ENGLAND. One of our Rose Bushed have a sticky Leaves i just saw a little what looked like a Green Worm quite small x What could help x I know i have a Budworm had them on one of our Roses a couple of years ago, they buds did not open out, found that Green worm today. Stickly Leaves .
Have a look for pictures of rose slug sawfly, another of the likely culprits.
🙏🏻
i've been spraying neem oil & water -- they sort of help but not 100% today 2 green caterpillars (7:51) formed circles on leaves next to each other :(
I had so many of those saw flies last year, even when I thought I'd picked them all off they'd still show up
Btk is a pretty unfortunate name
Yes, makes it sound far more sinister than it needs to be.
Thanks again I can't find the three BTK products on your Amazon site 😫
Hi Monique. The distribution of pesticides (even biological ones like the BT formulations) can be complicated by state regulation, and they seem to be intermittently available on Amazon. BTk is pretty commonly available and I've added a couple of examples to my Amazon store. BTi is also on my list (although I have it on there as "Mosquito Bits"). BTg is a newer products (sold under names like "BeetleBgone") and I haven't seen them on Amazon at all - even from the main distributors there are restrictions about which states they'll ship to.
I’m having the same problem now 😅😢😅
I have 7 roses, dahlias, old fashion Melva……Japanese beetles are eating them alive.😫😡 thank you again for info.👍🏽🙏🥰
This year unlike any other year, my roses got these cuttings that are like circular of the leaves. I was baffled because there is no deer in my garden because I live in the city. Maybe rabbits but my garden is fenced in. I was thinking a caterpillar. But it must be the bee because the leaves cuttings are so neat and clean.
Some bees cut out a circle and use it to plug where they laid eggs.
Thank you for the video Jason! If I may ask, how do you get rid of mealybugs? I only have liquid dish washing soap, vinegar and baking soda on hand. I don't have pesticides at the moment. Do you need to hose it off?
I think horticultural oil is the general recommendation. Neem oil or vegetable oil (canola or other light oil) might do, but just watch for any toxic reaction to the leaves as well.
@@FraserValleyRoseFarm thank you very much!
Ahhh BTK are very infamous initials
Hi, thank you so much for all your videos. I have spit bugs aka thrips - how do I get rid of them? Is it a sign my container isnt big enough? I have Gentle Hermione in a container on my deck. Thank you?
Spit bugs and thrips are two different pests.
@@FraserValleyRoseFarm thank you! How do I get rid of spit bugs? I have something eating holes in the leaves. I have used the bt in the soil for thrips... the rose is in a container.
It's not that I mind using modern chemicals but in most cases I'm satisfied with sulphur, Bordeaux mixture and tobacco leaves infusion.
Thanks. I keep it pretty simple myself. I haven't tried the tobacco infusion, but I'd hear from a few people that it works pretty well.
I live in Puerto Rico. No deer or rabbits. Mine has tiny holes 🕳 some has notches. Just like you showed. And those beige looking patch color.
Is that rose of sharon with your rose bush i was told they spread quickly and over take ?
I definitely have to rake out the seedlings in the spring.
My Peggy Martin seedling's some of the leaves are turning brown on the tips. Could it be due to overwatering?
Could be. It's a pretty general symptom to narrow down - root damage from any cause can show up on the leaf tips. but it could also be high humidity (depending on how it presents)
@@FraserValleyRoseFarm yes, it's very humid and hot these days in Houston, TX.
I've had squirrels eating my climbing roses since I planted them this spring. I just started spraying capsicum mixed with water, onto the tops. There is some indication the leaves are not too happy with that treatment. Ideas?
Tough to think of a solution that would work for squirrels (other than to bribe them off to a different food source)
Jason, help! I have looked everywhere and I can't find the answer to why my rose bush blooms look wilted the moment they bloom. The buds are tight when they begin and we water frequently. We have a ton on new growth on the plant, so I don't think it is a water issue. This rose has performed this way since I bought it. However, when it was potted before I transplanted it in my new garden I finally got the perfect rose. After transplant, I am back to the wilted rose. Do you know what the issue could be?
Well, just to rule out some sort of transplant shock or root stress from the move, I'd let it settle in a bit and see if the problem persists.
@@FraserValleyRoseFarm ok! We will take the wait and see approach. I walk my garden about 4 times a day (it is not huge) and I get excited when I see buds that look nice and healthy. Thanks and I appreciate your reply! I will keep watching. I am learning so much. We have 20 roses 16 tea and 4 shrubs. Thanks again!
Japanese beetles are feasting on my climbing rose. I forgot to use a systemic in the Spring. Is there any remedy for this at this point?
You could try the traps, but I hear they sometimes attract more JB to the area than they can trap.
Hi Jason, Please help. Bud worm chewing up my roses. I am using BT.K but doesn't seem to stop them. What else should I do? Thank you
Perhaps a product with spinosad? It's less toxic (organic based) than other pesticides, and had a pretty broad effect.
i did several rose cutting with rooting hormone. & i put them in soil. i put them in a humid environment with air flow. my stores near me don’t have fine bark. they sell huge pieces of mulch / wood chips. will my cuttings be fine in soil? ):
A potting soil is better for propagation that natural soil from the garden. It doesn't have to be bark based: a peat/perlite or coir based mix will do fine as well.
The top new baby leaves have little holes.....and it doesn't fall into none of these three categories...what could it be that it is causing..? Three of my roses that I just planted few weeks ago in different locations in my patio have the same issue. :(
I've sometimes seen similar damage from little weevils.
Thanks, that was helpful. I’m a newbie with only one rose bush which is in its second year. The leaves are just veins now, with most of the green chewed off. I had aphids and sprayed them with Neem oil but it didn’t seem to help. My question is what to do now? Do I cut them, leave them till the next time they need to be pruned? The whole plant is affected.
As if that wasn’t enough, I have another problem. The rose is called Alfred Sisley. It’s still fairly small but suddenly one side started growing long canes that grew much faster the the rest of the bush. I cut them off. Just wondering if Alfred Sisley could have been grafted on to a different rose? Is there any way to prevent that from happening? I’d really like to nurse the bush back to health. The multicolor petals are so pretty. Thanks for any advice. Kathy, Pennsylvania, zone 7.
Your 'Alfred Sisley' definitely could be grafted, and if you identified and cut down the suckers, that's great. They may reemerge from the same area, so just be watchful and aggressive in cutting down those shoots. They may look different that the rest of the stems (sometimes paler, or with a different leaflet count or thorniness). Long-term, I'd encourage you to take some own-root cuttings from the proper scion stock, and the resulting plants will of course be free of the sucker problem. The aphids didn't do the chewing - that's another pest. Have you seen Japanese Beetle? You can strip the remains of the skeletonized leaves and remain watchful for the chewing pest. Neem is not a fast way of knocking down pests (in my experience).
@@FraserValleyRoseFarm Thank so much for your reply. There have been Japanese beetles in my garden but I haven’t noticed them near the rose but that doesn’t mean they’re not there. I didn’t know that about Neem. I’ll look up how to take root cuttings. I appreciate you taking the time to reply.
I hope I didn't confuse things with my reply. I definitely mean stem cuttings.
Im living in South Africa and some areas have termits and these eat the roots of rose bushes.
Termitea
Hi Jason,
What about black spot?
Mine has black spot also
Thanks Linda - Blackspot is a tough one. I have some tips here: czcams.com/video/ulx5GyaHAZg/video.html
I have small circular holes in the bottom half of my rose bushes but not too much on the top half or on the new growth. Any ideas? What kinds of damage do slugs and/or earwigs do? I'm in zone 5b
My first impression would be slugs or snails.
@@FraserValleyRoseFarm I and my husband thank you so much for answering and in such a timely fashion. I will put out some cups with beer near the plant base and see what shows up. I have done this before and it works . I remove the cups as soon as I see dead spiders in the cup which means they are chasing their food and I don't want to permantly alter the balance of Nature. We LOVE you videos and have learned a GREAT deal from you. Please keep posting!
I’m ready that any liquid soap/water will work for the rose slugs.. especially blue dawn, what’s your thoughts on this method please? I’ve never had them before yesterday… I killed about 25 on one rose😢 I knew if I came to your channel, I’d get the education I need to deal with them. Thanks 💐
Just watch for any discoloration/damage to the foliage from dish soap (detergent) - it tends to disrupt the waxy coating of the leaves. Real liquid soap (horticultural or castile, potassium salts of fatty acids) does the job with less damage to the plants.
Jason, I need your help it’s not to do with roses, I wrote on the lavender video but I didn’t get a response yet, I bought lance lavender at Lowe’s for a dollar each, please tell me these are English lavender and I also bought super blue lavender for a dollar each so I bought 60 plants for a dollar, you are my hero on telling me the right zones and I learned so much from you, I need to know did I buy the right kind, please answer me ASAP so my heart will be relieved, thank you,
By the way in a big spray bottle that you can buy at a dollar store, put 2 tsp of Dawn dish soap and fill the bottle with water, shake it well and spray away, I have been using this for years, it gets rid of every bug, I also use it on other flowers, shrubs, if you get the flowers don’t worry about it, it will produce more, but make sure you do this on sunny days if it rains on you don’t worry you can always do it again
Hi Gabby. I try to get some time to reply to comments every 2 or 3 days. If it's more urgent than that, Google is available 24/7! ;-) Yes, 'Superblue' is quite a nice cultivar of English lavender (angustifolia) and that sounds like an excellent bargain.
@@FraserValleyRoseFarm , I know you are so busy, but these names they come out with google i just couldn’t understand if I bought the right one, , like the Spanish I bought I had to return it all back thanks to you, cuz the tags say -10 f, , I really appreciate you answering me back, , I feel relief, I just don’t know why I can’t find English lavender, instead they come out with these names and that scares me , I need to ask my pro and that’s you, even though I try to google it it doesn’t say the zones or if it’s English, thank you so much
I have two roses that are in pots that were my mom's. I want to bring them in for the winter but do I have to worry about those slugs with other house plants if I can't get them all off or miss one?
The rose slug sawfly will only really trouble your roses, so not such a risk to your other plants if you miss one or two.
@@FraserValleyRoseFarm awesome thank you.
I live in AL and I have NEVER seen this thing before. It is like a black fly ( it is not a fly) but it looks like a beetle. If you walk up to the bush and bump it they will fly up but right back down... What could that be?
Interesting Rachel. There are so many little beetles and weevils, I wouldn't even know where to start!
I've been using btk for my roses, but it didn't fix the problem, turns out that its rose slug ask sawfly, Not catepillar, 😅😅😅 sighh, I'm gonna go home today and spray all over my rose with Safers 3 in 1, 🤞🤞
Does anyone know what he means by insecticidal soap? New gardener here - thanks!
Not dish soap (detergent) but real potassium salts of fatty acids. It's actually sold under the same description (insecticidal soap) by brands like Safers
In Australia it's the possums that eat the flowers and buds
Thanks - interesting to hear rose pests from different climates.
deer occasionally
Have you had any luck with wasp attracting plants or attracting more birds into the garden?
Thanks Jonathan. Yes. A good variety of companion plants has helped out a lot: czcams.com/video/g-siKEX_wok/video.html
Finally, it looks like growing roses is just a nightmare.
Meh, about the same as most plants - everything has its own particular pests.
Excellent ! Thanks so much I have the sawfly worm only on 3 of my roses that are planted alone they do not get my Rugosa's or the hardy pink roses that are good in the far north. Maybe they laid eggs under the 3 that are separated by their own? Thanks again. I was going to use diatomaceous earth but I think I have insecticidal soap.They ended up last year (by the time I noticed) they looked like lacey skeletal leaves almost see through and almost killed them very young plants first year. All the best to you !
