5-Year Weed-Shield Landscape Fabric, 5ft x 100ft Black Polyethylene Bulk Roll, by Dalen Products

If you want a product that lets in moisture and keeps weeks to a a minimum, this is your product. Any weeds that grow through holes are easily removed when they appear. If you wait too long, you may rip the plastic slightly. Attack them early.

I have used this product for years. It is one of the few products that allows moisture to penetrate to the ground. I have never used mulch on top of the product. I weigh it down with bricks to keep it in place. Any weeds that grow through the microscopic holes are minimal and easily pulled. Great to warm soil in spring. Great garden helper.

I buy this every year and lay it down in my raised beds and it keeps all the weeds out for the whole summer

I always use this for my heat loving plants. It does a great job of keeping the weed down, but you need to weed first before you lay the film. I especially like this because you can water through the film, unlike most products.

The description doesn't say this, but this product needs mulch on top to be completely effective. Without mulch, weeds will still grow underneath it.
