Hello –

Mulch will control weeds, but when using bark make sure to put down a heavy layer — at least 3 inches thick. Wood chips and bark are not as compact as other organic mulches, say leaves or grass clippings, so more is needed to block out light and prevent weed seeds from sprouting. You can also cover the soil with a weed fabric or layer of newspaper/ cardboard prior to putting mulch down to really “block out” weeds. When working in landscaped areas, mulch around perennial flowers and don’t pile it too high around trees and shrubs. Still having trouble we offer a whole slew of organic weed control products here.

Hope this helps!
