willow tree branch cutting
Can tree shoots be kept from re-growing after cutting from main trunk, like spraying with Round Up without hurting tree? I'm tired of spending hours of work cutting them back every year. The trees are over 35 years old.

If your wanting to kill off the main tree, then yes, you can treat the root weed sprouts with a herbicide.
If you don't want to harm the mother tree do not use a herbicide on the root shoots.
You will need to cut them back by hand.
