It appears from my interpretation of the 2 videos that I linked to earlier in this thread that it would be safest to consider that previous diagnosis not based on the transfer by grafting technique should be considered suspect until more experience with the PCR test is obtained. It would be nice to have pictures of the 6 failures that they mentioned and pictures of future failures and future positives.
Sounds good. If you do like Cecile Brunner for the bed next to your house (where this one is now), the bush form is very mannerly - I have had two of them for 10 years, and both of them are only 4-5 feet tall. You could replace your house eater with a BUSH Cecile.
Beware, though. There is a THIRD form of Cecile Brunner (they just proved this recently with DNA analysis) which is called "spray Cecile Brunner" - it gets much bigger. Good Luck!~

I don't really want more than one of them. I like it, and THIS one plant of it has significance to me since I bought it the day after my daughter ran away from home and the day my father died (NOT a fun 24 hours...) but one thorny wonder of it is enough. I'll get something else to replace it that blooms more for me than this one does (it's only repeated when it lived for a time in a rather hot San Jose yard) with bigger blooms.
That will be fun pondering!

I work in a garden center that carried KO, as well as a few others. Usually they are just super neglected and also suffering from the effects of shipping - and sometimes being left in the refrigerated trucks for too long. Many end up developing black spot and other problems.
That being said, I've bought a few clearance roses (HTs and Floribundas) that had an assortment of problems. I pruned the problem leaves, gave it a spray, and watered well. I haven't fed them yet, but after a week they seem to have significantly recovered and are putting out new growth. I'll probably feed this week and have high hopes they'll recover nicely.
I've heard the KOs, especially the climbers and carpets really take off.
Fungicide spraying is preventative, not curative. You have to spray BEFORE it gets bad.
After about ten years of growing GC, I would note the following:
1. GC is quite vulnerable to black spot, as mine gets it here where black spot is pretty uncommon and mild, while 95% of my other roses never show a spot.
2. GC doesn't like hard pruning, so take off as little as you can. It forms a nicely shaped plant without much correction needed, just deadhead to keep it blooming.
3. GC has truly nasty prickles--I never go near it without gloves.
'Harison's Yellow' is not actually a climber, but it is a pretty rank grower so if there is something nearby it will probably clamber over it..
It's really a "plant it and forget it" rose - almost a species (although technically it is a hybrid). It's one of the feature roses of the Heritage Rose District of NYC- it was originally discovered there back in the early 1800's. It does tend to sucker a lot, so if you plant it in your garden, keep that in mind. Otherwise, it's easy and not particular at all.
In fact. it was so easy that cuttings were carried west by the early settlers and you see it all over now. So it certainlycould be the one from your childhood.
Some people compare the "fragrance" to linseed oil, which is probably the closest description of it. Not your typical rose fragrance.
Oh hello, I'm still here! Since it FINALLY quit raining everyday, the backyard has finally dried out some. I may have been overemphasizing the drainage problem somewhat due to what was going on at the time. I have started layering organic matter all along the back fence to improve the soil there. That is usually my "wettest" spot, so hopefully improving the drainage properties there will help the backyard as a whole. I am going to see how that works first before doing anything really drastic or expensive.
I have already taken the first step and limed with dolomitic lime to increase my pH and improve my magnesium and calcium deficiencies.
Glad things are looking better. But improving the texture of the soil doesn't solve a drainage problem. Where is the water going to go? A bed of fluffy soil surrounded by clay will fill up with water faster than a bed of clay surrounded by clay--unless the bed is raised (or you have an outdoor sump pump :).
Thanks to all for responding!!
Anthony... The website info on SeaCom does not specify if it is to be used as a foliar spray or added to the roots. Your response would then make me question if the results would make a difference in how it is applied. As a foliar spray, I was considering using it once or twice most. I was looking for the results of more leaves. I should also add that I use RoseTone as a soil fertilizer. I do add alfalfa pellets to the soil every spring to encourage basal breaks.
Henry...OK....so some seaweed can have heavy metals in it...I am using this strictly for roses....no vegetables. But, I also do not use any e.g. pesticides, etc. for fear of hurting my dogs, wildlife, etc. Took soil samples today as a "just in case" I may be low in magnesium.... and am very PROUD that there were many earthworms in the soil. I am relieved to hear from you that your interpretation of what PAN is stating "very little testing has been done". If anyone on this site would have read anything regarding toxicity, it would have been you or michaelg!
Thanks!

Regarding the use of too much cytokinin. In tissue cultures the cytokinin/auxin ratios are critical. In grown plant applications I could not find any references to problems due to high cytokinin usage. Of course theoretically it is possible (if the plant does not have built in self regulating protections). Does anyone know of any published problems?
If the leaves grew out that way, it is RMV. RMV is more active in cool weather and the leaves that emerge later in warmer weather are less likely to show symptoms.
Although opinions differ, most of us would keep the plant. It takes several years for PJ to amount to anything.
If it is a very large arbor, Nahema and Laguna are strong growing, very fragrant pink climbers with some blackspot resistance. For a normal sized arbor, maybe Heritage, a large shrub that is trainable, nearly thornless, and fragrant. It is susceptible to rust if that is a problem in your climate. Renae is a nice small climber with light fragrance, also not too thorny.
Lavender Lassie is a flush bloomer here. It provides two heavy bloom cycles each year. Once in spring and another in fall. It is not a rose that will have a few blooms on it here and there after the spring flush. Instead, after the spring flush, it puts on lots of new growth and then reblooms heavily in a fall flush once the weather cools down. In a BS heavy region like Seattle, I would go with Jasmina or Laguna instead of Lavender Lassie.
The great thing about having a rose garden is that you can plant whatever you want for whatever reason you want.
If you like orangey-colored HTs, you might want to look at "Liverpool Remembers" - it's really pops in the garden. Aside from its thorniness, it's a nice rose and IMHO a much better one than "Oldtimer". for that color range
Have you checked out the possible causes of collapse that I described? Jeri is not telling you to uproot the plant, but to pull on it to see if it has any roots.
The wilting is a different issue from the single cane, but the single cane suggests something is wrong with the site or the cultural practices, or else this plant is somehow a dud.
If you haven't done any kind of spraying than it has to be some type of root ball issue. Do check to see if it's still firmly rooted or not.
I have brought back a one cane wonder to a decent plant by digging it out and potting it so I could give the best sun and attention. It requires a lot of patience though and isn't always successful. But if the root ball has been destroyed there probably isn't much hope.
