Hi Laura. This is why I ended up removing several rose bushes in my garden three years ago. I have not regretted it. They are the most high maintenance care. If I have to constantly fight rosé disease to me it’s not the plant for me. I did end up keeping just one knock out bush. I severely pruned it last spring. & bounced back. Yes I had to deal with black spots also. It’s a pain I was planning to rip this one out too but decided not to. Yes patience is key.

[@GardenSanity]

I can relate, since I also removed several over the years too. But these Knock Outs still remaining are usually manageable - except for this year. 😅 I have other roses in the backyard gardens that are doing great. Who knows: next year it could be the opposite and those roses will be a problem. Gardening and Mother Nature are unpredictable! 🤣

Your knock out roses are beautiful as always! Didn't know you'd had this problem. Having KO roses, I know how wicked their thorns are. That must have been really treacherous getting inside the branches. Glad that they've come back, and as I said, just beautiful! Hope your weather wasn't too bad! - Doleen

[@GardenSanity]

Thanks Doleen! ❤️ Yes, usually the black spot has stayed within bounds using Neem Oil, but this year was a big mess! 🫣☹️ I use rose pruning gloves and they really keep my arms protected from the thorns, even though they can be hot in the heat of the Summer. Now getting my t-shirt caught on the thorns is another issue. 🤣🌹

[@KM-gi4xf]

Thank you so much for the information on removing the leaves in stages!

[@didi46]

Thanks for this helpful video! I have been slowly removing affected foliage on my roses, and was glad to see that was one of the steps you mentioned. The new growth looks so much better on my roses too, so I intend to stay on top of this issue from the start of the season next year.

[@GardenSanity]

You’re welcome Didi! So glad that slowly removing the affected leaves improved your roses as well. And I’m with you: next year - no matter what the weather - I need to be hyper vigilant so this never happens again. (Never say never…but in this case I’m saying never!) 🙂🌹

[@soniewhitten4844]

beautiful garden, thanks for sharing. be safe.

[@GardenSanity]

Thank you Sonie! 😊 We were fine through the storm - only had one branch break on one of my Pinky Winky shrubs. The winds were intense! 💨💦

[@Annabee399]

Great tutorial and a beautiful garden. 🌹 🙏💝 God's blessings, Ma'am.

[@GardenSanity]

Why thank you so much Anissha! 🌹😊

[@SnappyR]

Great video Laura - your roses are beautiful ~ now if only there was a soil drench we could use for the Hydrangea Macrophylla and their dreaded leaf spot - 🙃

[@GardenSanity]

Thank you Snappy! (I keep calling you Snappy, as that's what your screen name is, so I hope that's ok!) I wrote an article awhile back about leaf spot on mophead hydrangeas and this might help you: www.petscribbles.com/black-spots-on-hydrangeas-goodbye-for-good/ I agree they are not that easy to take care of. 🙃🙂

[@eliselook]

As always, thanks for the tips, Laura,; Your roses look not only healthy but HAPPY after your care ❤! I planted my first ever two roses this year (Angel Face and Le Petit Prince floribunda roses); they both had black spot from the nursery; on Angel Face I (ignorantly) removed all foliage at the same time which *fortunately* grew back quickly with over a dozen blooms and healthy rich foliage! I left some foliage on the Le Petit Prince and that has grown back arguably better than the Angel Face with the chubbiest blooms and glossy green foliage. I think I'll keep my rose collection at two and persist to planting more panicle hydrangeas, dark colored ninebarks, and fragrant butterfly bushes 🤣! Thanks again for the helpful videos!!!!!

[@GardenSanity]

So happy that your roses bounced back and are doing great, Elise! The colors of each are so pretty and soft - they must look stunning in your garden! Are they planted near each other or in separate areas? You made me laugh about planting other shrubs, because that’s what I ended up doing…especially going a bit hydrangea crazy. 🤣🌸

[@eliselook]

@@GardenSanity ❤ the two rose shrubs are in my "pinks" section around my home and are not planted right next to each other but about 10ft away from each other with some other plant goodies in the mix. I am with you, I'm going hydrangea crazy and not afraid to admit it 🤣 Looking forward to your next video!

[@user-pw7rr2bd6q]

Pretty ❤

[@GardenSanity]

Thank you! 🌹

[@pattijacobs100]

Good for you! Congratulations! I gave up! My knock outs are on their own! LOL

[@GardenSanity]

🤣 You made me laugh out loud Patricia! I thought my own Knock Outs “could” be left alone, but geez they had other plans this year. 🙃🙂

[@pattijacobs100]

[@K414nn4]

I had tons of problem with rust, black spots and powdery mildew and ran to your link just to find out this product can't be delivered in Massachusetts 🤔😪 I wonder why... Great video and the rose bushes look Gorgeous!

[@GardenSanity]

Glad you liked the video! 🙂 That stinks that the Bio-Advanced can’t be shipped to Mass. ☹️ I wonder if you can purchase it at a home improvement store, although it isn’t as convenient… I hope you can find it. Keep me posted. 🌹

[@willaerley7140]

I’m buying new roses next year. I cheaped out on $10 bare root ones from HD and most are pretty weak.

[@GardenSanity]

If I was going to buy new shrub roses, I would try Oso Easy Italian Ice because of the multi-colored flowers. The entire Oso Easy series (Proven Winners) claims no spraying or deadheading needed. Sounds promising!

[@CA-rx9ze]

I love to see other people grow roses. I however find them to be a bit to fickle for my garden habits.

[@GardenSanity]

They are indeed fickle -- that's a fantastic word for them in my experience too! Knock Out Roses are not -- in my opinion -- low maintenance like panicle hydrangeas, for example. We used to have these Knock Outs in several of the front yard garden beds, and slowly removed them for happier shrubs that are much less work. But I'm determined to keep these roses going! 😃🌹

[@CA-rx9ze]

@@GardenSanity They are beautiful.

[@gardeningjunkie2267]

Are you sure that's not spotted lantern fly damage? They've been all over NJ for the past two years. Those little brown spots are usually the first sign of them before the black spot sets in really bad, brought on by the spotted lantern flies. Especially because it's on a plant that is known for being very black spot resistant. I understand why you used the systemic, however if bees feed on your roses, it'll kill them. If you can use one plant as a trap crop and just treat that one, you can kill them safely without harming all the pollinators (just remember to remove the rose buds on that plant).

[@GardenSanity]

Definitely not spotted lanternfly damage -- but many thanks for suggesting it as a possibility. 👍We had some lanternflies in our backyard this year, but none on our roses in the front yard thankfully. The lanternfly nymphs usually don't show up in our area until later than when this occurred on my roses. Spotted lanternflies will eat leaves and suck the sap out of stems of roses, but any "black" residue on leaves and stems is usually resulting from sooty mold that develops from the honeydew-like substance they excrete after eating. This black mold looks quite different than black spot fungus (diplocarpon rosae). Yes, using chemicals is never my favorite idea at all, and I have another video where I explain what I normally use, which is much better than a systemic soil drench: kzbin.info/www/bejne/jJCrl6h-bNp6bqssi=rkW626FBzt0uyW47

[@richbishop7896]

Are you going to continue using the spray next year? Bonny

[@GardenSanity]

Hi Bonny, I’m definitely going to continue using the Neem Oil Spray, and I’m also going to apply the soil drench in the Spring. It supposedly lasts 6 weeks. I think using it as a “preventative” treatment will help. I don’t want to repeat what happened this season. ☹️😀

[@richbishop7896]

I think I will use it next year too.@@GardenSanity

[@GardenSanity]

Here’s hoping it helps our roses breeze through the Summer next year! 🌹🤞

[@amanguleysa2571]

Just give receipts please

[@cherylthompson6786]

Do you have Japanese Beatles? They ruin my roses every year.

[@willaerley7140]

I remember as a kid, our roses being totally covered and skeletonized by those beetles. I check every day in late spring and crush them. They say that using grub-ex on the lawn helps in prevention, but your neighbors probably have them, too. It’s really only for a month when they leaf out that you have to be on patrol.

[@GardenSanity]

Hi Cheryl, I didn’t see any Japanese beetles this year, thankfully. As Will mentioned, Grub-Ex works great, or you can use beneficial nematodes or diatomaceous earth to help control the grubs (which are the beetle larvae) in the ground. But the best way is to hand pick them off. If you wear garden gloves, it won’t feel so gross. Maybe next year will be the year your roses survive them! 🪲🌸😀
