I've got this next to my house, northwest corner 7B, figuring it would be a bit tender in this area. It (obviously) has done well, and generally the blooms don't all freeze out during our heat / freeze cycles in the spring. I'd like to trim it down, not drastically. Can I do it now? Anything to watch out for? Most of the buds that are going to open have, but I can wait another week or 3 if suggested. (or much longer, such as my typical pruning schedule -- years...) (the pictures were taken a couple/few weeks ago)
