Hi all. I have this blue hydrangea which I think is a lacecap variety. Here are photos I have of it when it bloomed years ago and the last photo is the current status, I'm at zone 7b and been a "let nature take its course" person, but I want to get back to gardening and care for it going forward.

I read that lacecap mostly bloomed on old wood, am I okay to prune the old stems without any growth or should I wait a bit longer? Thanks!
