Get matched with top mulch and topsoil pros in Harrisville, WV

The most important thing to put under a rock garden is the appropriate soil. The specific soil needed will depend on the type of plants you’re growing as well as the environment you live in. You can also put non-woven or woven fabric under the rocks to add to the garden's structural stability.

You should add 1 to 4 inches of mulch, depending on your garden type and needs. Keep in mind that no amount of mulch can completely prevent weeds, but a heavier coverage (closer to 4 inches) can suppress weeds enough that you are only seeing them sprout every few weeks. Finer mulch prevents weeds more effectively than large mulch, so if you’re using mulched leaves or shredded bark, 1 to 2 inches will likely suffice, while 3 to 4 inches is best for larger mulch, like bark chips or straw.

Most experts recommend a quarter-inch layer of compost for best results, and you will need about .77 cubic yards of material per 1,000 square feet. To measure how much compost to use, take the square footage of your yard and multiply it by .77, then divide that number by 1,000.

Mulching any time of year can attract termites, so there’s no added risk in the fall. The important thing to remember is that termites are attracted to rotting wood, so you need to lay a thin enough layer that won’t trap too much moisture and lead to rotting. A layer between 1 and 4 inches thick should provide all the benefits you’re looking for without attracting termites.
