Use instead of plastic/fabric
Would RecommendJust recently did my mulch for this year and I got tired of putting down plastic/fabric as the weeds still found a way through. Decided to give this a try this year and put it in before the mulch. So far I haven’t seen any weeds and if it stays like that for the year I’ll definitely be buying again
