"Own root" means nothing when considering RMV. If the plant from which the cutting was taken is infected, the own root plant will be, too. If the original stock of the variety is infected, until it is heat treated to remove the infection, every plant produced from it will also be infected. That was the original issue with many US roses produced in the middle of the last century. You can't find an uninfected plant if all the stock was infected to build the quantity of material required to introduce the variety. It finally became such an issue that it is much less likely to find newer roses infected, but it is by no means impossible. Kim
Mine gets horrific disease, I'm sorry to say. I just got it last spring (2013), so maybe it will grow out of that. I'm adding a picture of it from last December (center pot). Brother's Grimm, Dark Night and Grandmother's Hat were the worst fungal offenders last year.
I would say with pretty good certainty that it is RR. As a mature plant, it is very thorny as Ann Cecilia pointed out, but on an immature plant with non-hardened canes, you can't really judge it solely based on that. It is definitely not Dublin Bay, nor a Rugosa.
All this said, there are a number of reds that look very similiar, but I do believe it to be an immature RR.
Maggie, the rose slugs are probably gone now. But if some of them are still there, washing off the underside of the leaves will get rid of them, along with the mites.
It's amazing -- but really, the most effective solution isn't a chemical . . . it's something as simple as water at high pressure.
To be truthful, this is a great deal of fun, on a hot summer day.
Thanks to everyone for all your information regarding the aphids and ladybugs. I NEVER use chemicals in my garden so I know I'm not hindering lady bugs from going on all my roses. So far, I've just been either hosing them off or putting on my thin rubber gloves and spritzing them with my water, oil and soap mixture and removing them by hand. I was just wondering if they would crawl back on the roses after hosing them off. I love the photo (above) with the lady bugs on the leaf. Thanks for posting it Holly. That leaf sure looks healthy to me.
My experience is similar to Holly's. I released many of them this spring twice weekly over two weeks. The aphids had already infested so I will get on it earlier this year. However, I've seen ladybugs here all summer and lots of ladybug love going on. It's great to see the larvae.
I also bought praying mantis pods and they hatched! I scattered about 800 praying mantis around my yard. Have seen a fewâ¦

Right, don't fertilize until they have recovered and have put out plenty of leaves. Bloom Buster is the wrong kind of fertilizer--regular Miracle Gro or Miracle Gro for Roses is fine, or any reasonably balanced fertilizer such as 10-10-10 or 18-6-12.
Watering correctly is the most important thing. Keep a 2" mulch of leaves or bark around the roses. When the soil under the mulch feels dry-ish, water thoroughly with 2-3 gallons for small plants or 5 gallons for larger, plus or minus for extremely hot or very mild, cloudy weather. Usually once a week is fine. For new plants, I divide the ration in half and water twice a week.
Soooooo beautiful!
Thanks all!
Thanks for the tip, Zack! Mine is in morning sun now. Maybe I'll move it into more sun.
