I first cleared the ground, then a strong weed killer, then this ground cover. On top of it we have a few inches of rubber mulch. Hoping to be maintenance free going forward. I saw a couple folks saying this product does not drain and water pools. Though there may be temporary pooling, that's simply because it's seeping through slowly. The product is doing it's job. I will certainly take temporary pooling above it rather than seeing weeds in the future. There was a problem with my order. Vevor took care of it swiftly. Kudos!
