Ever feel like you are throwing money away every time a big thunderstorm rolls through. You spend an entire weekend hauling heavy bags of cedar chips, carefully spreading them around your flower beds until everything looks immaculate. Then, the clouds roll in, the skies open up, and suddenly half of your hard work is floating down the street or pooling on your sidewalk.

The shifting material gets trapped in the trench, making it incredibly easy to just push back into place. Plus, it gives your lawn a crisp, clean border that looks super sharp.

Plastic and woven fabrics create a slick, smooth surface. When rain falls, the water can’t sink into the ground, so it flows across the top of the fabric like a waterslide, carrying your expensive wood chips right along with it. Removing these slick barriers lets the mulch grab onto the actual dirt beneath it. This natural friction keeps everything grounded, and as a massive bonus, it can actually boost your plants’ root growth by up to 400 percent because nutrients and water can finally
