Q.Why have my knockout roses stopped blooming?
In previous summers they have bloomed continuously until around Oct. or Nov. I live in GA so we have more warm weather. This summer they started out beautifully but now have stopped blooming. What is wrong?
There is not necessarily anything wrong with your roses. It could be that they are between bloom cycles and are just catching their breath so to speak and will bloom again. Just as cold sends roses off into dormancy, the high heat can cause them to take a break. Keep them watered and fed, they should come back into bloom nicely. Keep any eye on them for insect attacks too, as the stress of such attacks will limit new buds and blooms. If buds start to form but fall off, you could have thrips. Also be careful what fertilizer you are feeding with as high nitrogen fertilizers can easily lead to more foliage and no blooms. Check out this article link too:
