I have 4 lilacs, they are over 8yrs old. I have barely been trimming them and this year I only have one really good lilac that has already produce a few blooms. The others look a little worn down. They only have like half of the leaves too. Do I wait until fall to cut them back or can I go aheafd and trim the branches that don't have any leaves??
