Mulching is one of the best things you can do for your trees. It helps conserve soil moisture, regulate temperature, suppress weeds, and improve soil health. But not all trees benefit equally from mulching, and how you mulch matters just as much as whether you do it.
Young and newly planted trees benefit the most from mulch. These trees are still establishing roots and are vulnerable to water stress and temperature extremes. Mulching around their base—while keeping the mulch away from the trunk—gives them a strong head start.
Fruit trees like apple, peach, and plum also thrive with mulch. It keeps the soil moist and prevents weed competition, helping them focus energy on fruit production. Just be careful not to pile mulch against the bark, which can lead to rot or pests.
Shade trees, such as oak, maple, and elm, appreciate mulch too, especially in urban or suburban areas where grass or compacted soil can limit their root growth. A layer of wood chips or shredded bark mimics the natural forest floor.
Evergreens like pine and spruce can also benefit from mulching, especially during dry or cold seasons. Mulch insulates the roots and keeps moisture levels more consistent.
In short, most trees benefit from mulch when applied correctly. Spread mulch in a donut shape, 2–4 inches thick, and keep it a few inches away from the trunk. With proper care, your trees will be healthier, stronger, and longer-lived.
