Hello. I have 6 plants (3 on either side of my front walk) that have gotten extremely huge and find myself needing to move them over about 12-16inches so I can have my front walk again :). Anyhow, since they are in bloom (with their plumage in full glory,) I guess now is not the time to do that.

Would October be too late to do this move? And would it be ok to divide them then or should it be done in spring? And can anyone tell me is there anything other than for appearance sake, does cutting the grass down after blooming in the fall or in the beginning of spring does to affect the plant growth or hardiness?

Thanks for reading and have a good day!
