Yes, apparently the plumbing of the rose runs more vertical than horizontal, with roots on one side more connected to the canes on that side. You may have to dig the plant and bare-root the part you are trying to save. It is worth trying this if the crown is splittable, but, with those own-roots that make a tap root, you can't split it. Perhaps you could get a bit of root with a cane stub and treat it like a cutting.
I tried splitting twice and it didn't work, but I would try it again. I drove a hatchet blade with a heavy hammer to divide the plant. The plants survived but RRD symptoms recurred.
Looks like sawfly larvea (Rose Slug) damage...
Pick them off the bush or use Spinosad which works well.
Follow directions...
You sure you do not have some time of animal eating your leaves off besides the rose slug damage?
I left our younger Double Knockouts unprotected last year and rabbits ate them to the ground.
Now I place fencing around them until they mature alittle...
The bush should be ok...
I have these also. They actually look a bit different to me than sawfly larva. A little bigger and greener--more caterpiller-y looking. As well as more damaging in a shorter period of time.
I'm going to spray with a little spinosad and see if that works.
Hi Dragoonsers
I live in Sydney and have 13 roses, including 3 very tough climbers. I don't know how easily you can get hold of the roses you want.
There are some easy roses for this warm climate. Do you have access to Australian bred roses? My (Alister Clark) Nancy Hayward climber is still young but starting to be the perpetual bloomer it's famous for being. I'd recommend you get it for your climate. I feed it with slow release rose food twice a year, and give it diluted weed tea now and then. I just snap off dead flowers and chop off any canes that make any moves to invade my neighbours' place. I'm a relatively new gardener but find this rose my easiest.
Jeri I'll see if I can get my hands on that book. Problem is tea roses I think will be hard to find. We have all sorts of Modern Roses but I don't think Teas (they have such weird proper gentlemen names) which I have never heard of locally. I do have this rose, I'll see if I can find a picture. Its own root and has been grown really well. I just attached a picture. What class do you think it belongs to? I like the shape. Its unlike the austins, and the modern ones.
Jackie you're right about the weather. Humid summers, dry winters and spring
KingCobb we don't get rust or blackspot (even though its so humid at times). Spider mites do attack often.. And most roses are grafted on centifolia.
Henry why not share some names?!
And Ross I don't think Australian roses are available. Most roses are modern, "wild ramblers" and austins are available too. I'll see what I can find though. Thank you for your suggestion!
Um, tricky, Coconutty cos I have/had the first 3 but will have to try very hard to be objective - and as I always fail, my opinion really is quite worthless....but anyway, FWIW, GdD - this rose needs a tender warm wall to really do well in dreary and damp England. I tend to grow all my plants quite hard - while many of them thrive despite themselves, GdD is not one of them. The same could be said about the next on your list.....or at least my version of it. There are several roses with this name (Mme Louis Leveque (I grow the pink moss), but clearly, I do a rubbish job of it because it was a mean bloomer which looked nakedly horrible for a lot of the time. On the other hand, for a clearly slack gardener, Purple Skyliner has been a winner - requiring very little in the way of fuss and attention, PS throws out several generous flushes, with dainty little flowers and fresh green leaves, with a sweet scent and a forgiving nature in its flexible non-prickly amiability. A playful, delightfully informal rose.....and one which might be just the ticket to welcome you back to the pleasures of the garden - well done, you.
The only one in your list I can comment on is Mon. Tillier. Planted several years ago, in full hot sun, watered well the first year, I was just looking at him today - full of blooms, not a spot of disease on his green healthy leaves. A good one. I have Purple Skyliner in a pot but its not big enough for me to comment. Good luck with your renewed interest in gardening!
Except for the babies all my landscaping is established and gets watered once a week. I've slacked off recently except for the roses. The babies get watered almost daily. Most of my landscaping is oaks and they don't get watered.
When there is enough rain and cooler weather that the ground stays wet, I stop watering until the weather heats up in the spring.
For me Firefighter and Velvet Fragrance are doing better than Mr. Lincoln. Papa M is wonderful but has mildew problems. I have a dry warm summer which is so much different than a rainy warm summer.
I can suggest
Tiffany
Memorial Day
Pink Peace
Eternal Flame
Radox Bouquet
Jardins Bagatelle
Yves Piaget
Firefighter
Pope John Paul II
Perfume Delight
These are the ones that bloom well here and have beautiful perfume. There are others that have more flowers but no perfume and those that have beautiful perfume but less flowers. The roses on my list all have strong perfume and bloom even through summer when the old flowers are kept picked off. I don't know how they would like heat and humidity but if you have humid air, I'm sure your roses smell very good.

I have to agree on the assessment of Buck's exquisite 'Quietness'. No disease here, hardy to the tips, vigorous as an own-root, constantly blooming, elegant bush habit with good foliage, lovely flower shape, pleasant fragrance and a calming, gorgeous silvery pink color that shows well in the garden and yet blends well with everything. It is also undemanding and doesn't seem to need massive amounts of water or fertilizer to be happy.
Is it the perfect modern rose? For me, yes. It is truly greater than the sum of its parts!
The follwing was stated by jokewing: "jJust wondering why henry kuska ONLY makes posts having to do with diseases and death? Has anyone else noticed this? Why is he even worried about roses if the thinks they are so disease ridden? "
H.Kuska comment:
Jockewing, perhaps your own post is a good explanation as to why I feel knowledge about what is known/unknown about rose diseases is important.

Yes Thornton, I hope you are right. With the amazing science we have today, I'm surprised more roses with such qualities have not been released. It just baffles me that the most beautiful flower we are able to grow is plagued with so many problems. Why must that be? There are so many beautiful plants that are such a breeze, but in my opinion nothing is so special as a classic hybrid tea rose. Why must they be plagued with so many diseases and pests? I admire the Knockouts, but I just don't think they are beautiful except perhaps in mass plantings from a distance, say at a commercial building or along the highway. We want giant flowered hybrid teas with the same vigor!!!
It really makes me sad that virtually NO ONE I know in my area grows any classic hybrid teas at all, with may the exception of a few here or there, usually in an older neighborhood."

Jockewing, Henry is a scientist.
If you were going to have surgery, would you make such a comment about a surgeon? Would it bother you if he/she were totally absorbed in his specialty that he did not seem to have a life?
Many of us are professionals, and we are driven and care much about our professional lives.
Why do you care so much about Henry that you would make such a comment? Before looking at the post you were able to see the title of it.

Was just at Chamblees last Tuesday and got Blue for You, Love Song, Lavender Veranda, Plum Perfect and Twilight Zone. I love lavender, so it will be fun to see how all these do. The Pacific Blue that I was lucky enough to get from Vintage is just opening a big fat bud and I cant wait to see what this one look like. Does anyone grow these other lavenders?

I love love love this rose. I purchased it at a plant sale a huge grower has in Georgia twice a yr. Mine does get blackspot and I do spray but get lazy. It's gorgeous and blooms well all summer. Does great in bouquets also. Can't remember the fragrance! Mine right now is about 5 ft tall but usually stays around 4 ft and about 2 1/2 to 3 ft wide. I say get that baby while you can. Judy
Do a web search for the pest called Chili Thrips. They are a world wide problem with many, many host plants and are especially bad on roses. They destroy foliage and without the foliage, roses suffer badly.
Two of the bits of new growth on your well established rose look good, but the one at center shows damaged leaves. That the buds are coming so low implies that the rose is stressed (that we see so few leaves is another clue.)
The state of Florida in the US has several good websites about these thrips and may help.
Roses just sometimes pop out different looking blooms, different shades, different forms, etc., it happens. Any kind of change in it's environment during bud set, and that was weeks before it opened, can trigger a change in the ultimate results. If the weather was a little wonky the week it set that bud or if you sprayed something at that time it could have affected it. Mark the cane and watch how it blooms in the future before taking any actions. It's probably just a one time occurrence.
Congratulations to Ann! Her work has definitely be invaluable. Thank you for all of your hard work!
I wasn't there at the start but I know you have gone to extraordinary efforts to understand this disease and help others to diagnose and limit the spread of RRD. I hope you see it dying out one day. Thank you for everything you have done.
