Mulch and Topsoil questions, answered by experts

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.

Yes, grounds count when calculating box fill. A single volume allowance is made when up to four equipment grounding conductors or equipment bonding jumpers enter the box. It’s important to account for all wires and fittings when calculating box fill. Beyond the first four, each additional grounding conductor should be counted as ¼ volume.

Wood from black walnut, magnolia, eucalyptus, red maple, and invasive species like tree of heaven are not recommended for mulching. These trees release allelochemicals that can suppress plant growth. Some homeowners, however, use wood from these trees for mulching if it is less potent due to age or concentration, or if the plants are not as sensitive to them.
