Two of my four older large climbing hydrangeas have been severely damage by the drought--they get more direct sun. In spite of watering when I noticed the brown leaves a month ago, one is 95% brown and dried up. The other is 50%. Should I cut the 95% one off to the ground and see if it grows in the spring? The other one?
The other two are still green but the next one in the row has a few brown leaves starting. I'm doing a long water once a week.
What should I do?
