Air frost damage
A couple of weeks ago we had a hard air frost (nothing on the ground) and 2 of my 3 Acers and my 30yrs old Hydrangea. The top of the Acers dried up and leaves fell. Ive now trimmed the tops of both of them and they look better. My Hydrangea on the other hand looks very sad with brownc crispy leaves on the end of each branch and no sign of any flower buds. So, can I repair the damage by cutting back below the brown leaves or do I leave it alone and have a flower free year?
