Prune the roses after the buds break dormancy. The major pruning period for knockout roses is in late winter to early spring, just as the bush begins to break out of its dormancy stage. 1  Check for bud formation on the stems of the plant. 2  You can still prune the plant even if new growth is starting to develop, though.
This would be a good time to prune in your area. You need to remove the black canes and any cane sections that show brown center pith when cut. If the graft (bud union) is not damaged, the plants will grow back and bloom about six weeks after pruning.o check, carefully dig some soil away around the base of the roses until you can see the graft. If there is sound growth below the soil, your roses should come back just fine. If they are alive, cover them back to their original depth and leave them. I personally would not do anything to them until you see new growth.
