Digging them out isn't an option. Our customer wants them kept, only smaller. Trouble is we aren't professional gardeners, we're only just starting out. Willing but not yet very knowledgable! From what I understand, we can dead-head them soon to tidy them up (we live in the south), prune a bit in about April but cutting them down now to about 4' which is what our customer wants (at the moment they are all at least 6' x 5') will just encourage lots of new growth with no flowers next year.
