I have 2 Salix Hakuro nishiki which are going brown on some branches, they were left out in the direct sunlight in the recent heatwave, I believe this may have cause the die back. Is there anything I can do to nurse them back to health? Help please
Surrey, United Kingdom
The plants are watered regularly and I feel I should prune them back but don't want to unless it's the right thing to do.
