Mulch helps slow down weeds in beds. Bare dirt in beds like the one below in this Richardson landscape is just begging for weed seeds to land and take root. We’ll be installing 2″-3″ of fine shredded hardwood mulch and that will create a barrier that weeds have trouble penetrating and when they do it’s a lot easier to pluck them out of mulch than trying to get them out of our clay soils. If you’re looking for a non-chemical method of controlling weeds it doesn’t get any better than this. An added plus is the hardwood mulch breaks down into the soil giving it great organic material.
