I'm wanting to put mulch and edging around ornamental trees and shrubs in my yard. Will roundup hurt my trees if I use it before laying down the mulch fabric and mulch? |
Round Up can hurt the roots of your trees and shrubs so don't use it to kill any weeds beneath them. It's a contact killer and can harm any shrubs or perennials in the vicinity. Instead, dig the weeds up, roots and all so you have a clean slate, then lay your weed barrier fabric and mulch over the clean soil. The combination of the weed barrier fabric and a few inches of mulch will keep weed seeds from germinating and your trees and shrubs will be weed free for several years. |
