I'm planning a new rock garden, and I'd like advice on whether to lay out landscape cloth at the base. My plan is to create a mound of tufa (with a sandy mix filled in between the stones) above the existing ground, which is loamy soil. Is it worth using landscape cloth to try to discourage worms? I don't think I need landscape cloth to discourage weeds -- the site was a lawn with few weeds.
Thanks for any advice.
