For clarification, I have recommended such fabrics when working with river rock for drainage patterns or a swath between a landscape and the house foundation. It’s also helpful in rock gardens. In fact, in those cases, it’s an awesome product to keep the stones from working their way into the soil. But you will still have weeds set up shop in the tiniest amount of dirt. So, weed killing and weed preventing with pre-emergent herbicides will still be required in these situations. And if you don’t stay on top of them, you will have a mess. I promise.
In my humble opinion, and I have plenty of experience to back it up, weed-barrier fabrics and weed-barrier cloths simply do not work in this region! Still, I know some people will use it. And if they don’t engage in continuous weed killing, they will eventually have a bed full of weeds tangled up with the fabric. Worst of all, you can’t effectively use tools to remove the weeds because the cloth interferes with your ability to dig into the soil. Y’all have to trust me … I’ve dealt with this so many times, it makes me crazy to think about it.
