Climbing Hydrangea- help?
We had a beautiful well established climbing hydrangea on the north facing wall of our house for many years. It’s flowered every year since we have lived here - 10 years and I’ve never done more than trim off the odd shoots to keep it away from windows. For some reason this year there are virtually no leaves on it at all apart from a few tiny half green leaf shoots lower down. Mostly it looks dead! I have no idea what to do and it looks so sad. ☹️
