UPDATE.. pics show what has happened to my beautiful knockout since my last posting. My husband had to use a power saw to cut off the main stems they were so hard, like oak. Pics show the interior of the cut off stem. Our extension agent says most wilt will show discoloration inside the stem and this did not. Note the new growth coming. We plan to keep observing and see if the remaining stem dies like the others. If it does, we will submit the plant and soil samples for testing. It's a real puzzler, wouldnt you say?




What hasn't been mentioned is the rest of the pruner, beyond the blade. It's easy for resins, etc. to accumulate on the blades. They need to be cleaned off and they need to be so smooth that nothing accumulates there.
Then the blade (for a secateur) needs to be sharp, as sharp as you can make it. And the side it moves past needs to be equally clean. Clean of everything from plant gook to rust because rust can hold and then spread microscopic problems.
To me, the most important to stop and clean secateurs is when you're working on a rose that has a problem. It's bad that that rose has a problem, what is worse is rushing through and spreading the problem (and I have spread fungi and worse from one rose to the next by rushing stem cuts in spring.)

Karen, I'm glad your roses did well! Queen of Sweden is one of my favorites, and Lady of Shallot is newly planted in our gardens.
Well -- I did it again. After three months in the hospital I was so revved up to create beauty (and also had a 25% discount code), I ordered a number of David Austin bare roots, mostly own root, and they arrived a few days later. I was still too incapacitated to inspect or plant them myself, but they're leafing out and one has even bloomed -- Princess Alexandra of Kent. They were planted in April with temps in the 90s, and I figured if they failed it would be a learning experience.
I had another bout in the hospital last week, and since I didn't get my fingers burned with the first round of roses, I ordered again after I was dishcharged (I suspect David Austin's marketing team has taken control of our hospitals here, and they hypnotize patients into uncontrollably craving their roses). Last night I found the bare roots on my doorstep, and with help, I inspected them and bucketed them in pond water. I thought they looked fantastic -- lots of green canes, good, long root systems. I'll post a picture later if I can. At Humpty Dumpty House we get donations of plants other people don't want -- roses that don't bloom, puny bare roots, and this year we even got my dream plant -- a bare root David Austin rose tree with a big greenstick fracture. So I'm used to looking at things that don't look so good. Our philosophy is to take take things (and people) that are considered broken and useless, and give them a new life; a chance to be beautiful and to serve a worthy purpose. Not saying that anyone who pays good money should have to accept an inferior plant. But reputable companies will replace it, and you can send the bad one to us (big smiley face symbol) because those ugly ducklings really can become stellar swans. I find the challenge bittersweet, and it makes me love these gardens and plants all the more. Plant donations are tax deductible, and your facebook likes are helping us reopen the gardens in June, after my lengthy hospitalization. Lots of pretty pictures, design ideas, garden advice:

Princess Alexandra of Kent. Planted from a David Austin bare root early April with temps in the 90s. I know David Austins don't do well everywhere, and feel sad for those who can't grow them 'cause they're magical here -- at least the ones we've planted so far. All our roses get fertile soil which we've been amending several years, and drip irrigation. Hot, blazing afternoon sun with morning shade. Many are planted against a white wall with a great deal of reflected heat. No spray. Great soil and adequate drip irrigation seem to overcome the negatives, because the roses are heartbreakingly beautiful. Many came from bad looking bare roots. Please see our website and facebook links in the post directly above.


I have the three Austins mentioned. Two will not do well not sprayed. Teasing Georgia won't defoliate, but gets spotty. Plus it's a monster. A friend has Julia Child and it does get spotty. The other yellows I have are Golden Showers, which is a climber. It gets blackspot. I have Kordes Caramella Fairy Tale, and that also gets BS. I just bought a bunch of yellows, but I plan on spraying them. It depends on what your tolerance for spotty leaves is. I haven't tried Carefree Sunshine, if Michael says it's good, maybe that should be the one you try.

I am growing Sparkle & Shine(The Golden Child) here in Australia for the first time and have found it good in my climate, I thought it might suit, here is a link to it,




The virus by itself cannot survive in the soil. The last lecture I went to they recommended waiting 7 days for the virus to die. But yes, the roots can carry it if it got down that far. I dug up a Reve d'Or last year and I'm waiting to see if any roots survive before replanting. It was own root, but in a confined spot so I could not get all the roots. I have had luck killing Dr. Huey sprouts with RU for woody vines. If you have RRD, I think that would be a good idea before replanting.
And honestly, the woman making that statement is a Parks and Recreation spokesperson, not an RRD expert.



Ryan, sorry to hear you have lost one. I only got one Sir Lipton Thomas, it's doing ok. I went crazy with Therese Bugnet this year, saw some at HD too, picked more there, now I have 12 of them. :-) Hope they have good fragrance. Good luck with your other SLT and Mister Lincohn. I got 2 Mister Lincoln from Aldi's this spring.



The rose came from my friend's spray garden, so there probably were no thrip predators. Hopefully, I talked her into using something less toxic like Serenade when her roses get mildew instead of the stuff she used this season.
I found this interesting article from Paul Zimmerman: Got Thrips on Your Roses? Get Aphids? It talks about how aphids are food for the thrip predators. I used to reach for a bottle of soap and water to spray on aphids, but now I think I'll leave them alone so the beneficial predator bugs will have something to eat early on. A few aphids aren't nearly as bad as thrips and the good guys like the hoverflies will soon follow :)
Thanks, again. Hopefully this rose will look better next season. It looks terrible now.



This might all be moot. A day of rose shopping netted nothing much that might work. I think I should have tackled this project a month ago. And the narrow space and the tracking of petals is a valid concern. I am thinking it ove. Meanwhile, I do thank everyone for the good advice.


Oh!! What a handsome horse!!! I love his color!!! The rose is pretty - but the horse is wonderful!!! :)

There is something special about that picture. It's mesmerizing.
