The answer to 'mulching maintenance tips' is to regularly maintain and replenish mulch around your landscaping. Mulch helps retain moisture in the soil, suppress weeds, and insulate plant roots from temperature extremes. It should be applied 2-4 inches deep around trees, shrubs, and garden beds, leaving a few inches of space from the base of plants.
Mulch should be replenished 1-2 times per year, typically in early spring and late fall. Remove any old, decomposed mulch before applying new material. Be sure to use a natural, organic mulch like wood chips, shredded bark, or leaves. Avoid using dyed or synthetic mulches, as they can be harmful to plants.
