I have noticed that my ground is covered with green mold, or at least I’m assuming it’s mold. Could you tell me what the problem might be and how to correct it? This is an area that gets full sun for at least 8 to 10 hours a day.

What you are describing sounds like moss. Moss usually grows in moist, dark areas that have a low pH soil (acidic). Since the area you describe is sunny, it probably has acidic or moist soil. You can either apply a moss killer to the area or scrape the surface to remove the moss. After the moss is dead or removed, you will want to improve the soil compaction (compact soil stays moist longer) by adding topsoil and peat moss to the area. You will also want to apply lime to help raise the pH level of the soil. Improving soil compaction and raising the pH level should prevent moss from showing up in the future.
