I can't find the memory stick the scans are on (I moved), and the ARS annuals are boxed in the garage, but in the seventies or eighties, there were at least two articles in the American Rose Annuals about the use of ground pine bark cleaning root knot nematodes from the soil. It was used both as an amendment, mixed in the soil as well as a mulch. Previously infected soils and plants were found to be "cleaned" of the infestation simply due to the cleansing action of the pine bark. You might consider using it if it's locally available in your area. You might also search this forum for the scans as I am sure I have posted them within the past two years when the nematode question was raised previously. Good luck.
Oh yeah, i forgot about the french marigolds. They are ridiculously easy to grow from seed (and fast to bloom) so if you can't find them at your local nursery seeds will be the way to go. Also the pine thing Roseseek mentions. Thats why I said to mulch heavily with pine based mulch in the first reply. I should have clarified that pine mulch repels them.
you might give it a try. I also drain the water out of the self-watering pots because my roses weren't big enough when I re-potted them to have their roots reach that far and I didn't want to rot the roots with soil that is too moist. If you plant something in a pot that is too big where there is a lot of soil around the roots, it is possible to keep the soil too moist for the amount of roots and then you will end up with root rot. Not good. Suggest you test your soil before watering - stick a finger in the soil - if soil sticks to your finger, it's moist enough. If it's dry, you'll be able to tell.
Do you have pictures of it bloomed out before? The trunk is very distinctive and if growth was always at the top part of the crown it might be a tree rose.
Was it a bush from ground up?
Like everyone says, if you don't want to shovel prune it, I would water but don't actively think about it or stare at it for the next month, month and a half. Good luck.
No I don't unfortunately, but all the growth actually were at the top when it used to grow, then from the bottom like the average rose. I was actually thinking it could of been a tree rose, but I'm just not sure now, not an expert lol. I asked my mum if she knew what kind it was as she brought it, but she's not sure either. Yeah, what I'll do is just leave it and keep watering everyday and see what happens in a few months, I think that's all I can do really now. If it doesn't get back to how it was and it doesn't look right, I'll probably yank it up and replace it.
Hi Diane,
This is a list of my current roses:
http://www.helpmefind.com/gardening/l.php?l=3.4702&tab=2&frmt=1&scp=0&order=1&qn=0&qc=3d
It has been whittled down from about 250 to 70 over the past 10 years.
The other 3 thousand photos I have posted on HMF are rose pics from my garden, pics from rose gardens on the west coast and pics from nurseries. Such as this one from my garden:
Just a funny note. I sent an email to the production manager for that news show. I explained their information error and suggested they vet their interviewees a little more closely. Someone responded and said they received a record number of complaints from gardeners and garden clubs all over the area pointing out their misinformation.
They added a link in their written article pointing to the correct RRD information. It is too much to ask I guess that they simply take the video off their website.
As to the botanic gardens, no one there will return a phone call on the matter.
Good for you, Beth. You beat me to it, lol. I'm still wondering how this guy can claim with a straight face to be a horticulturist. Even my MECHANIC, who has exactly one KO rose knows more about RRD. I'm not a bit surprised they got complaints.

Thanks for all the helpful responses. Michael, good to see you again. Ann, the leaves are turning green. I read your E book and I would really like to catch any RRD early, if possible. The top growth is flexible but I wouldn't call it rubbery. All the rapid growth in several roses has had me spooked.
I rogued out a rose and took in some canes to the UT extension. They said it "appeared to be RRD" but no mites were present and they didn't have a test to diagnose it. Just confirmed that it had similar symptoms. I was upset that I paid $25. If it didnt show symptoms of RRD I wouldn't have temoved it.
Thanks again! Susan
I'm in zone 6 and I keep my standards in pots. They get wrapped in burlap and stored inside my shed for winter. An insulated but unheated garage works best though. Find a really nice big pot and put it in that. You can still put the pot in that bed for the summer but you'll be able to turn it from time to time to keep the growth more even and it will be easier to winter over.
Soluble materials, including most manufactured fertilizers, will get through to some extent. Water enough to mostly dissolve them and then come back later with more water. I do it this way, although my mulch is not 4" deep.
Most organic fertilizers have to be in contact with soil bacteria to release the nitrogen. Blood and poultry manure contain some soluble urea, but the part of the N that is in protein form will not break down for a long time. Eventually it will get to the mulch/soil interface.
If it's been in the same pot for 10 years then I think it probably needs to be root pruned and new soil. Even in zone 5 with a short season that's a long time in the same pot. I'm sure it's root bound and the soil is probably completely depleted. Even with fertilizing you need to refresh the soil now and again.
What Seil said.
