Q: Hi Ken i have a willow tree in our garden which is 15-20ft high I need to trim it right back as it is intruding into other gardens. When is the best time to do this and is there any rule to how much i can cut it back? John
A: Cut the willow tree back as much as you like unless you are in a conservation area. Best time to cut the willow tree is during the dorment period November to beginning of March.
