Question: How can I best get my trees and shrubs to re-leaf after hail knocked many leaves off and damage the remaining ones etc.?
Answer: There's really nothing you can do for your trees and shrubs - they will develop healthy new leaves to replace those they lost in the storm. Just give them some time to recover and they should be just fine.
