Rose new Flush and sudden death?
Comments (1)What does the foliage look like? What sort of "white fungus"??? Powdery mildew??? How old were the plants? What roses were they? Where are you located? Jeri Coastal Ventura Co., SoCal...See MoreSudden branch death on Knockouts
Comments (3)I had the same thing happen to a couple of my rose bushes last summer. Still have no idea what caused it, but the seemingly perfectly healthy bushes died, one branch at a time until the entire plant was dead. I too assumed it must be some kind of rot or infection, but never found anything abnormal in the wood--other then the browness spreading down the cane. I replaced the bushes this spring. The new bushes are thriving and healthy. I speculated that after a bad drought one summer, I got in the habit of over-watering the following summer in compensation and that maybe the over-watering caused the problem--but I don't really know if any of that is relevant. Best I can advise for now is to cut those canes turning brown down all the way to the base, even if the bottom half of the cane is still green. And take care not to overwater. But I have no idea if that will help or not except to say that I tried that late last summer on a David Austin rose that had been growing beautifully for 5-6 years in my garden when it suddenly started showing the symptoms you mention. This year that DA rose is still alive and is bursting out in buds right now--although it is not the most robust looking rose I've ever seen--but we had that brutal winter, so I'm not sure how much of its less than optimum vigor is due to a hard winter and how much is left-over damage from last summer. But it is alive and looking healthy and getting ready to put out a good set of blooms--so let's all cross our fingers and think good wishes for my DA rose. : ) And for yours also.

Comments (32)Kim, Cynthia, Nik, Kippy, Lyn, and Anne, thanks for all the comments on watering and irrigation woes. I feel well supported! It is good to know that others have gone through the same thing and come through successfully -- or did not, and have good advice to offer. Sammy, Buford, Jackie, and FloridaRose, if you are reading this, now you know it is a drought issue combined with gardener error. I'd rather have it be that, because there is something I can do, at least about the gardener error part. And Jackie, I checked the rose you gave me. It was in a different area but it, too, seemed to need more water. I have fixed that. Jeri, I had temporarily gotten rid of the gophers inside the fence and was dealing instead with ground squirrels. I see that at least one gopher is now back, but not near the affected roses. Now I have ground squirrels and gophers. Sigh. We need a new dog. Well, we are planning to get one this fall. I will leave the ribes in place until fall brings rain. I hope it brings rain! However, I did have a ribes die on me last year in an earlier round of native shrub planting. The replacement did fine, but the two more I added do not look good at all. The Las Pilitas website is a favorite of mine, too. I have bought a number of plants from there, and my DH and I stopped at the nursery once and met Bert Wilson. We were sad to hear about his sudden death this past spring. Last night my knitting/quilting group came over and I enjoyed sitting down and relaxing with a completely different activity. It was very restorative. I may knit some more today. I may even read! I think the garden can get by with only brief attention from me today, perhaps an hour or two of deadheading.

Comments (4)There are a number of possibilities. It is a matter of narrowing down and eliminating as many as possible. It either happened from an above ground problem or a below ground problem. Below ground: What I would do is dig them up and examine the root systems. Dried out? Rotted? Does the soil where it was have a sour stink? Are there massive tree roots in the same area that are competing and robbing the roses of water and nutrients? Root or crown galll? Did the irrigation clog and the roses died for lack of water that went unnoticed? And so on. Above ground: signs of a disease like downy mildew or canker? Did a neighbor spray an herbicide?
