Questions About Knockout Rose Bushes

    Hello and thanks for posting your questions. Knockout roses are really no different that other roses, I will provide you a link to an article on watering rosebushes. I like to hand water all of my rosebushes with a watering wand so that I know for sure that they have gotten a good drink. I water either before things heat up for the day or in the early evening when the temps have started to cool. I like to rinse down the foliage and then water the roses at ground level. After rinsing the foliage down a bit, I start watering at ground level in a slow circular motion around the rosebush counting to 30 or 40 as I do so. The counting to 30 or 40 depends on how dry it has been. The dryer it has been the longer the count. Here is a link to an article I wrote on watering roses for you: >> https://www.gardeningknowhow.com/ornamental/flowers/roses/watering-roses.htm

    While early spring is usually preferable, in your area it should be fine to go ahead and do so now. This article will help: https://www.gardeningknowhow.com/ornamental/flowers/roses/prune-knockout-roses.htm

    They can be grown from cuttings and then would be own root roses. You certainly can transplant them to another area is so desired.

    Knockout roses are hardy shrub roses and will do okay with partial sun. Their performance is best with lots of sun but they are hardy enough to handle partial sun and still do a nice show.

    Let them have this flush of blooms. Then just as this flush of blooms starts to fade, prune them back. Feed them and water them well and you should then be fine.

    You might want to wait until it blooms or you will likely sacrifice many blooms in the first bloom cycle. If just a light pruning back is all you want to do, then you would likely be okay. However if it is a big shaping pruning, I would wait until the first flush of blooms is just starting to die back. Then prune them back, feed them and water well.

    I would take a couple samples of the soils in and have them tested. Let them know why you are having the soils tested so they know they are looking for something that killed the rosebushes. Knockouts are not easy to kill by any means! If it was the nasty Rose Rosette Virus that caused the problem, Having the soils tested is always a good idea so that you know what you may be dealing with if it is not the rose rosette virus.
