Rooted transplants from large bush

Question

I took some rooted transplants from a friend’s large bush and a couple of them are 4 and 5 feet tall with growth only on the tops. If I cut a foot or two off will they branch out from the main stock? And should I wait until they are dormant to do it?

Answer 1

Are they planted? If not, go ahead and plant them first and let the roots get established before you prune. Depending on what the plants are, their dormant season would be the best time to cut them back. Generally if they bloom in spring, don't trim till after they flower. If they bloom in summer or fall, it's usually OK to prune in late winter or early spring.
