Can i cut back the knockout rose now
The lady that helped take care of them left and I 'm not sure what to do. They look so out of shape and big.
You can certainly shape prune or trim up your roses. The Knockout roses are low maintenance roses so you do not have to dead head them (remove old spent blooms) unless you want to, as the old blooms will fall off and new buds and blooms come back on for another bloom cycle. Sometimes the rosebushes get a bit wild looking and not nice shaped bushes, you can certainly do the shaping pruning any time but if it is at a time when the bushes are setting new buds for another bloom cycle, many blooms will be lost until a new batch of buds is produced.
