How I’m fighting Rose Black Spot | Uncle Toms Rose Tonic | Comfrey Tea

- This is how I’m fighting rose black spot and powdery mildew this year. My roses have already had a feed with David Austin’s rose feed, a good plant based organic mulch and now I am applying once fortnightly foiler sprays of uncle Toms rose tonic. And a once fortnightly watering of comfrey tea.
With the weather we have had this year I’m expecting black spot to happen. I have zero doubts about it. But I’m trying to delay its arrival, spread and veracity as much as I can by keeping my roses as healthy as possible. And this is how I’m trying this year.

The weather is all over the place Jay Jay. My poor plants don't know whether they're coming or going. Looking forward to seeing how you get on with the tonic.
Thank you lovely Wendy, yes we will find out in the coming weeks and months. But I’d rather the weather just improve from now on in. ;)
The king is back!!! Always good to see what’s going on in your garden. I hope you and your family are well MR!
Ha ha that made me smile. The family are ok and thank you very much. I hope your garden is doing well also ;)
Yes!
Lovely to see the updates. Blackspot is only likely to develop in higher temperatures (20C+) so I think we are fine for now as long as May isn't going to be wet. I deliberately don't spray as I'm worried to damage the bees and ladybirds. I know some Kordes dislike foliar feeding and sprays so be careful with them. I'd honestly just feed them with slow release in the rootzone, this should prevent issues with foliage disease as they should withstand the threats better when they properly fed. Miracle gro 2 kg slow release is only £12, organic feed is similar price. But I know you like to experiment so I'm going to learn from you, please do share updates how it all goes.:)
Hi vorong. Interesting what you say. I dont think we have seen plus 20 degrees heat as yet but I do have some roses already with blackspot. Paul’s Himalayan musk is bad with it and powdery mildew. I’m also seeing the odd leaf with it here and there.
The David Austin rose feed has gone down already along with the plant based mulch on all of my roses this hopefully will take the sting out this year. They certainly have been fed properly. This tonic and comfrey just a little top up for nutrients wether or not it will delay what I’m pretty sure is coming I don’t know, but we will find out.
hm I guess, it could be some warm spells that allowed it to develop considering it can get warmer next to the wall/inside the bush? Here is a blurb from WIKI: The development of the black spot disease itself is ideal at temperatures ranging from 20-27 °C (68-80 °F). It is important to note that no infection will develop if the leaf surfaces dry out within 7 hours of the initial conidial germination. Similarly, temperatures above 29 °C (85 °F) also halt the spread of disease.
I've got no blackspot yet at all and we are even cooler and wetter here in Midlands.@@Jay_Jay
@@vorong2ru you could well be right my friend. It says at least from the Wikipedia it’s just an ideal heat 20 degrees so it could be active a little lower I guess. I know last year we had a very wet May if you recall. So that may have helped the spread last year I don’t know. But I do know not feeding with anything the blackspot will spread to even the healthy roses if grouped together. Let’s see how things develop this year. I know some dry weather won’t go a miss.
Good to hear your voice again! I see your beauties are doing well
Thank you yes doing well at the moment,let’s see how long it lasts :)
Lovely to see new growth in your roses. Yes, potassium is known to make leaves hardy.
Thanks Rakesh

Hello jay.
A lovely and informative video.
Your roses are looking healthy.
I started using Uncle Tom’s last year, unfortunately I didn’t keep up with using it every 2 weeks. This year however I’ve started early and have been persistent with the routine .
Like you I’ve used D/A feed as well, I’m hoping with the combination of both my roses will benefit , & be healthier.
Ray is finding using the sprayer with U Toms more easier and quicker than the usual watering can with tomato feed.
I hope you & Donna are well xx
Hi ronnie hope both you and Ray are well. Yes as you can see I’m trying a few things this year to try and keep blackspot down. Hopefully something will work but time will tell. They are certainly getting plenty of nutrients that’s for sure. :)
A very informative video Uncle JJ. Nice one 👍
Cheers mate
Thank you for showing your roses and how to care them. I can see the a lot of buts of roses, and am looking forward to flowering. 🥰
Thank you I hope your roses see many flowers this year ;)
Great Information. Believe it or not my Darcey Bussell already has black spots. So early in the season.
Hi Naomi. I can believe it. I had darcey bussell, a lovely rose but always one of the first to get blackspot. I ended up getting rid. :(
@Jay_Jay I'm just sat here having my lunch and up you pop, how lovely. You have roses blooming already. I'm much further behind than you up here. I hope the tonic helps, will be interesting to see how you get on with it. it's been so wet I'm expecting black spot in abundance this year. Good luck with the comfrey tea it is good but boy oh boy does it pong something awful :( I think you can do a no stink 'dry' leaves version where it rots down without the water added, into a second container underneath and that doesn't have the strong aroma the water version has. Looking forward to seeing your garden in bloom very soon 🌹
Hi Linda, yes I’m pretty sure with the weather we’ve had it’s going to be another year for blackspot. I’m just trying to delay it as much as possible. Last year I gave up entirely. Let’s see what happens this year. Im not counting that rose just yet It’s been stuck like that for ages. We are seeing freezing temps here overnight I’ve had to de-ice my car several times of late. I’m not sure them buds will flower completely. But we can hope :) hope your well.
Jj sir good information.
Thank you Syed :)
Your garden is fantastic!
Thank you. It is for now but the million dollar question is for how long :) I hope your garden is doing well.
@@Jay_Jay Thanks for the warm words. Now I see your roses will grow better and better, you became a professional. The one thing I would recommend to you is a battery powered sprayer (9-12 l) . You will save time and get a real enjoyment using it. Such sprayer use all the liquid until the very end. Try it😄.
Hi Jay! Prevention is always good as long as your not spraying toxic chemicals. We have something equivalent with that here in Germany called Vitanal, I have one in my basement, just bought it and never used it, good that you reminded me with this video. Your right with this on going changes in our climate, rose plants are stress out. I‘m not familiar with Comfrey, what is commonly used here is Nettles (Brennessel), not tried it because of the smell but interesting. About blackspots, I diligently removed all the leaves that were affected already in late fall. They will come back again in late fall but very mild. Let’s see what the summer brings, I hope for lots of roses, enough rain and a friendly wind.🌹
Yes let’s hope so. Nettle tea is similar yes but not as good as comfrey tea I’m told. But similar thing. Thanks Gemma
Jay, we've been getting rain and my roses are blooming.❤
Awesome Debbie. In your climate rain is very much wanted I’m sure. And with your heat I’m sure they will grow huge ;) best of luck Debbie and thanks for
I started using sulphur rose. Too early to tell whether it will work. Roses in bloom currently Madame Alfred Carriere, Rosemary Harkness and Rhapsody in Blue. Out of 86 roses...... Love your videos, keep them coming 😊
Jay Jay I appreciate your helpful video, the funny thing is I bought last autumn "Uncle Tom" , like you I used DA slow release. I didn't forget I had " Uncle Tom" , it's just that I wanted to see if the DA was the complete solution. It's great that you made enquiries, so now I'm gonna be able to use it also.
Further I was looking at Sulphur Rose also, I seen a video that seems a good option.
Will be interesting to hear if Megan has good results so she could advise us also :)
Lovely selection. Yes please keep us updated how you get on. Where in the world are you just so we know what climate your in. Rosmary harkness is one of my favourite roses let me know what you think of this also. Last year for me it wasn’t the healthiest but I liked it so much it didn’t really matter if that makes sense. I’m hoping this year we see improved health. Thanks Megan.
Ps I’ve subbed your channel just in case you chose to upload anything :)
I am in Sittingbourne, Kent. Zone 9b???
@@Gez_rosa_newby hi there sorry I just seen this. David Austin rose feed has pretty high levels of nitrogen, im trying this with mulch uncle toms, and comfrey tea I’m throwing everything at it pretty much. But there’s no knowing if this cocktail will work but I know that there’s a lot of nutrients going into my roses this year.
I know that I am seeing blackspot from a few roses that had only the mulch and DA rose feed until now. Paul’s Himalayan musk is bad. The Gertrude’s at the front of the house, that has blackspot and spreading fast. Wollerton old hall and Madame Alfred. All of these roses had blackspot to some degree beyond minor. And these roses had only da and mulch so I’m not sure in my garden da feed alone will be enough this year. That’s why I’m trying more. But Time will tell.
Iya jay love your videos, i to love roses, but every year i get sore fly, dont no how to stop them, eny ideas please 🧚♀️
Great video as always-how did it go, I’ve been picking leaves off many of my older roses, new ones are ok so far. Comfrey tea smells soooo bad-I remember the first time I did a mix, nearly 🤮,🤢, a great feed but no one warned me about the smell 😂
Hi Jay Jay…very interesting, Phosphors is great for Root and Bud Growth, it sounds a bit like Vitanal, often used here in Germany from Kordes etc…we had very cold nights here, -4 C, lots of frost damage from this cold spell and before that they started already with Rost and Mildew 😮, no Blackspot jet but I already used the chemical solution…because of other opinions I didn’t pick of the leaves bevor the winter and I think in this mild month the spores of these fungus leaves just creeped in every stem…well it will be interesting to see the results…❤
Hi obiwan. Well I hope it warms up where you are your evenings sound colder than here. Yes better to pick the infected leaves off because of you delay it will spread even more. Last year admittedly I gave up eventually and stopped worrying about it. This year I’m going at it with renewed vigour. :) best of luck in your garden.
As a Rose enthusiast, we’re constantly trying to find ways of keeping our rose healthy and I’m definitely one of those. I’ve been using uncle tom’s for couple year now, whether it helps my roses or not I’ll probably never know. I keep telling my sister Lin about this product but she never listen. Now seeing you using it and experimenting she’s gonna probably want some.😢 This year I’ve tried sulphur potash which helps root development and have healthier roots to fight off and rose disease. So another product to consider maybe? Well at least with did our best and only the weather to blame.
Sulphur potash yes I have heard this is good. But I’ll wait for your luscious sister Lin to advise me on it, if she recommends I’ll definitely try it :) 😂😂😂😂
I thought you had a secret fish recipe also? Well I’m trying this for this year we can only wait and see how things develop but like I’ve already said we could start with some dry seasonal weather. That would be a very good helping hand indeed. But this year I’m not sitting on my hands doing nothing. I tried it and my soil just cannot be good enough on its own. Thanks Ken.
@@Jay_Jay lol 😝 I think she has more confidence and trust in your rose knowledge than she has in me , and without doubt your way more wiser.
@@kenvoong5977 she would be foolish to think this Ken. The pair of you very smart and knowledgeable. ;)
A worthy experiment for a rose enthusiast, J Jay. I sprayed sulphur rose in Feb, not sure if it will make any difference, will wait and see. Keep us updated with its performance. What is name of the green Acer in the pot? I have few Acers, your acer plant appears to have narrow foilage. Thanks for sharing such a informative video.
You’re welcome raj and thank you. The acer I don’t know. It’s pretty old. Best of luck with your roses I hope they remain disease free. ;)
Always good to see a video from you my friend, and good information in this video, and how is Seanie? :D
Hi Jason. Seanie is good we took him to the vets last week. Had some teeth out that was troubling him and some scans but he’s very healthy now touch wood, cheers mate
@@Jay_Jay Bless him :D
My wood ashes soaked in water then strained keeping the liquid form a very strongly alkaline potassium hydroxide. Wood ash lye, decades ago I made beautiful, wonderful soap from wood ash lye. But extreme care would be needed to not harmfully alter the soil alkalinity. Your comfrey liquid with t'
s nutrient profile is somewhat similar to my wood ash lye but not harmfully alkaline. Thank you for the show and tell!
Hi Ralph soap made from ash there’s a thing I never heard of. Yes comfrey tea they say is very good for roses boosting its health. I’m hoping it all works but time will tell.
@@Jay_Jay Yes, that is how our ancestors made soap, lovely soap with the slightest hint of lavender fragrance. Midnight here in Ohio, too late for more comment. Thank you for your reply!
@@Jay_Jay ..... Elm ash liquid make the most reliable, very best soap. Strained and filtered until impeccably clean of course, then reduced over heat until a raw egg will float half mast in it.
I was thinking about something today Jay, one of my roses was covered in sticky sap from a load of greenfly all on one side of the plant. The leaves looked shiny from the sap. Those leaves are getting loads of blackspots and the other non sticky leaves look healthy. I'm not one for spraying but I did think this was interesting.
Hi Hailey. This is isn’t like rose clear or bug off type spray. I wouldn’t use those. But uncle toms it claims environment friendly.
@Jay_Jay hi Jay sorry my comment wasn't clear..baby brain lol. I wasn't commenting on the rose Tonic..looks good tho I'm going to try it too. Was just walking in the garden and noticed the blackspot on the sap covered leaves so wrote this thinking out loud.I know you are a fellow non bug sprayer :)
Last year had black spot , hardly any this year and have 50 roses .south coast UK .
Hi there, yes I’m surprised I haven’t got more black spot at this moment in time. Unsure if that’s because of the treatment or just fluke. Do you treat your roses in anyway?
Another interesting video Jay Jay. Will you be doing a 'Control' to see if there's any visible difference? I'm picking off any old leves I see with blackspot at the moment too. I don't know if you've got a 'Golden Showers' climbing rose in your garden but from my experience they don't like being sprayed with anything - they get upset. I'm keeping an eye on the wheat in the field adjacent to your garden too. P.
Hi Peter yes I am doing a control. The pair of boscobels I have out the front and the quartet of Eustacia vyes out the front. All of them have been fed with David Austin’s rose feed and mulched. But only half will get the comfrey/uncle toms treatment. It’s not scientific of course but they are right next to each other I may see a slight difference.
Interesting what you say about golden showers, I haven’t got it but I do wonder if other roses won’t take kindly to it. One of my Rosemary Harkness has become unwell I can’t work out why. The other is fine. The farmers field out the back with wheat you mean if he sprays it?
@@Jay_Jay Good morning Jay Jay and it'll be interesting to see what your trials show. I noticed this morning that my Compassion has quite a bit of blackspot on it already so I'll have to do something about that. Always something catches you out. I hope your Rosemary Harkness picks up. Re the wheat, I guess the only sprays going on now will be to keep it healthy; nothing to bother your garden. I'm just waiting to see the ears come out at the end of May along with your roses. I've had no frosts in the last few days, have you? P.
@@peterhaymaker7562 hi Peter, no frosts the past couple of days but I know I had to scrape the car of ice a few times last week in the mornings. I think we’re still seeing low single digit temps of a night though? I’ve just mentioned on another comment my Paul’s Himalayan absolutely full of blackspot. The Gertrude’s that I have out the front, pretty heavy blackspot. Madame Alfred got a fair bit. And also Wollerton old hall. Apart from Paul’s Himalayan the blackspot seems to have very quickly arrived in the past week or so and prior to me spraying. Paul’s Himalayan impossible to defoliate I will probably take this out the moment it flowers. I am considering today defoiliating the Gertrude’s as they are pretty bad. So I don’t think we will see a lovely first flush with full foilage from them this year. Not a good sign considering we are only in April. I can remember only a couple of years ago I was disappointed to see blackspot in July!
@@Jay_Jay Hi Jay Jay and thanks for the reply. The Blackspot on my Compassion I'm sure had come quite quickly. I do wonder if the very windy weather, coupled with the continuous rain, has bruised the leaves and left them more vulnerable to disease. I'm sorry to hear about the blackspot on your other roses. My Mme. A. C. seems OK at the moment. I'll have ot keep my eyes open. As I said before, as you don't live far away from me, if you'd like to take a closer look sometime just let me know. P.
@@peterhaymaker7562 hi Peter what’s your email address ?
Last year I made my own little experiment and used only biologicals. I don't know if it's available in the UK but I managed to keep mildew and black spot under control by using Trichoderma and Bacillus subtilis. They are not advertised specifically for roses but nevertheless worked great.
Hi there, I’ve never heard of these i will have to look into them, they sound hard core but it obviously worked for you. ;)
@@Jay_Jaythere is nothing hardcore about. I did not mention commercial names just because I have no idea what's available on consumer market in the UK (Trianum-P probably is the only exception). Both Trichoderma and B. subtilis function as fungicides. They are used in agriculture for years, especially in growing salad greens where hard chemicals are not allowed. Trichoderma is very useful in composting. There are strains specifically selected for this purpose, usually it is marketed as cellulose destructors for autumn use. Trichoderma is applied during watering, B. subtilis mostly as spray.
And the most interesting part (at least for me): both of them can be easily cultivated at home. Trichoderma is easily cultivated on sterile (boil it for 20 minutes) barley or wheat. B. subtilis is cultivated on weak sugar solution with a little bit of plant fertilizer. Recipes for growing medium can be easily found in expired patents.
... both of them are safe for humans and pollinators. In my country it's fourth class ("safe, if used properly") which roughly equals to American "generally recognized as safe".
@@TimurDavletshin awesome. And how did your roses perform still good growth and flowering ? Did you give them a feed also or just the biologicals you menrion?
@@Jay_Jay Well, in my climate by beginning of September roses start to lose leaves because of blackspot, mildew etc if no chemicals applied. But last season I managed to keep them in decent state until first frosts just on those two biologicals. In fact I tried all biologicals which are certified on local market. I tried number biological insecticides too (Metarhizium and Beauveria) in addition to Bacillus thuringiensis and avermectin which I used before.
Fertilizers: I have nothing against chemical fertlizers and use those along with compost and manure (when I can get good one). I use nothing branded, everything from local producers (essentially what farmers use). But I tried growing nitrogen-fixing bacteria this winter (Azotobacter vinelandii from biologicals used by some farmers). It works on Petri dishes (it can grow on Ashby medium, which doesn't have source of nitrogen) but I'm not sure whether I need it.
In terms of blooming... well, depends on season but I wouldn't say that I had reduced or improved number of blooms. But B. subtilis definitely improves quality of tomatoes. For mechanism you can google for "bacillus subtilis plant endosymbiont".
What is the chicken wire for?
Hi there. Strange I know. It’s to keep the rabbits from feeding off my roses. I’m shortly going to be lifting it the rabbits seem to have plentiful food now. Somehow it’s worked I was told to try it, the rabbits don’t like to walk across the mesh and looks a little better than caging the roses.
@@Jay_Jay oh, that makes sense. I thought it might be to keep the rose leaves off the soil whilst treating them for black spot
prefer only liquid food for roses every 2 weeks, black spots come from stress and bad soil/lack of feed/bad weather conditions...never experienced problems
That’s great what liquid feed do you use and where in the world are you ?
@@Jay_Jay South of Scotland, mainly Westland and Miracle-Gro. The only thing I Am particular with is that I never pour water from watercan on the leaves, which makes me the weirdest weirdo walking with a bucket of water and milk pan with a long handle, lol, pouring it directly towards the bottom. I do have aphides every start of the season though, which I learnt mainly to fight manually (takes time) and spraying soapy water. it works.
