Hello, I moved into a house a few years ago that had beautiful flowering hydrangeas. I haven't had much luck with them flowering since then. I was reading about hydrangeas and see that there is a difference between old wood and new wood. Are usually trim them down to the height of my knees (marked 2022 with the red arrow in the photo). I went outside to trim them earlier today, and I see all these buds (green arrows) underneath the decaying flower from this past summer (yellow circle). I'm really confused now because it looks like the 2023 flower that bloomed over the summer bloomed on new wood. But if that same stem is already forming buds, doesn't that make it an old wood bloomer?
