No damage other than yellowing leaves, which then got brown, kinda crispy in fact. The death seems to happen from the top, outside of canes and then continue down until the entire cane is dried out and dead. I should add we use a watering system as needed but that most of last year it was turned off due to so much rain. The root systems are freaking amazing. They spread for ten feet or more and are healthy looking (I had to cut some to plant my new bushes). We have no RRD in my area that i am aware of and I saw no signs of anything odd other than the dead leaves. We had a HUGE amount of rain last year. Enough that my Hybrid teas (in the same yard) defoliated and stayed that way even with spray. We had almost NO sun to speak of. Winter was VERY cold for us, but this doesnt appear to be winter damage so much as something just causing entire canes to die, then the entire bush.....its something I have never seen before. They are single red knockouts. My double pink is 6 foot tall, 6 feet across. never defoliated. bloomed until Jan....its in the bed next to the hedge....I know I need to prune, and YES should have done it earlier, but I got so busy at work this hedge just got put on the back burner...btw, my Belinda's Dream Hedge is 8 foot tall already in the next bed, literally 4 feet from where the KnockOuts are. My rosebeds are framing the parking lot of my shop on three sides, then there is a sitting area with a potted rose area on the opposite side of the walkway. This is my double pink KO This is the Belindas Dream, last year. This is my shop parking lot. the top left of the photo you can a bit of the hedge. You can see where right in the middle of it there are new plants. That is where the ones died..if the entire area was in the shot, the lower left would be the Belindas Dream, and the DPKO is in the upper right. I was standing with the potted area to my immediate right, so everything is in close proximity....the only ones giving me a hard time are the KnockOuts in the hedge.....I am lost. BUT I will be pruning them back this weekend and hoping that helps. The Belinda's Dream is headed toward getting "chopped" as well. It is own root and putting out lots of new canes from the bottom, so I need to top prune it...sigh....the work is never done! LOL

Growing roses from cuttings is a fine addiction and yours look very healthy. You spoke of rose sports and I have a Moon Shadow that is gorgeous but won't propagate at any method. I finally found a healthy rooting sucker or sport that is growing well but still small with thin canes but we'll see. My question for you is, I've kept my roses tall this year five plus because something is eating all the lower leaves, up to two ft, of the tops. It breaks my heart to see empty canes or flowers that were just ready to open totally gone. The backyard is at the base of a mountain covered with trees. In the front of the house all my roses are tall and flourishing .I'm always experimenting and in the kitchen windowsill have the base of a stalk of celery, some carrots and green onions all rooting well and begging to go outside in the dirt. Now if I put these in a large container close to the roses next to the gazebo which are being eaten, would you think the animals would get into the veggies instead of harming my roses. Poisons, systemics,animal be gone junk, electric devices, sour milk and Tabasco, nothing is working. These aren't big animals, just rats under my gazebo which love to thrive on poison and sometimes squirrels and rabbits.

Thanks for posting a photo of your Knock-out wall; that's a really nice use of KO. About 15 years ago, I had a good HT garden in New Haven by rotating Banner-Max and Immunox. Now we reside in a latitude that allows me to grow antique teas and I don't spray a thing. I'm sorry that you're not getting better results with Bayer Advanced. Perhaps there are roses you simply shouldn't grow. Sorry. The White Flower Farm catalog shows a couple of Easy Elegance roses that you should consider for your second wall. [Yes, I know that WFF prodeucts are over-priced but the catalog is my favorite winter garden porn so I order a few things each year to stay on the mailing list]. Take a look at EE Coral Cove and EE Yellow Submarine. I haven't grown either but EE is a good series of roses and both are the appropriate size for your wall. Good luck -- and please post more photos of your gardens. TIA.

Mary, I was at Home Depot just last weekend, and they had several pots of Iceberg. This was mid-peninsula. It might be worth calling around. I was also at Regan's last Saturday and they had a lot of roses - it was the first day of their half-off sale. I don't recall seeing icebergs but I wasn't looking for them in particular. Again, definitely worth calling to check. In my small garden, iceberg is the only rose I have several plants of. They are simply spectacular in So. Cal. but aren't too shabby here in the Bay Area either. Mine get cercospora spots but are rarely out of flower. They are my workhorses. Jo
