Get matched with top mulch and topsoil pros in Weston, ID

Although it’s not required to lay anything under mulch, it can help to put landscape fabric or plastic weed barrier down and lay mulch on top. The barrier helps keep weeds from growing up through your mulch. It also helps keep rodents and insects from burrowing into the ground underneath.

Pea gravel can retain some heat, but it generally stays cooler than materials like concrete, asphalt, or stone pavers. Lighter-colored pea gravel reflects more sunlight and tends to stay cooler, while darker-colored gravel can absorb heat and become warmer to the touch.

A light layer of mulch can help protect a tree, retain moisture, and keep the soil healthy. However, it’s important to avoid over-mulching or piling the mulch up around the trunk of a tree, a practice notoriously called “volcano mulching.” That piled mulch can increase the chances of rot and disease on the tree trunk as well as overwhelming the soil, which needs access to a certain amount of air. Topped trees have it hard enough: mulch sparingly while they heal.

If you’re using crushed stone or gravel as a base material, then yes, you should compact it to prevent movement of the top layers. For instance, if you don’t compact crushed stone or gravel and you lay pavers on top of them, the pavers will shift over time. However, if you’re using gravel or crushed stone as a top layer for aesthetic purposes, you might not want to compact the materials.
