Answer: Moss is usually a symptom of several problems, including poor drainage, too much shade, low fertility, compacted soil, and soil that's too acidic. If you can correct these problems, you'll have fewer moss problems. Failing that, you can scruff the soil up every few weeks to aerate and discourage moss growth, or you can put a layer of bark chips over the bare soil. Since you can peel it up, go ahead and remove the moss, then either cultivate the soil regularly, or spread a 2" layer of mulch over the bare soil. Best wishes with your garden!
