There's never going to be a perfect time for anything. There will always be a reason not to. The day I went all in with those two lilacs, we were dog sitting, but toddler was roaming around and I was trying to keep track of all those moving parts without killing the lilacs. But I started, and it looks great. Well, it will look great soon... I hope. No, I know it will. They look a little rough up close right now, but with anything, put in the work now and reap the benefits later.
