Get matched with top mulch and topsoil pros in Culbertson, MT

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 mulching in the fall, aim to lay down the material right after the first frost, which will vary by climate. Late October and early November are good time ranges to aim for. Try to lay down your mulch after a light rainfall to lock in moisture for root growth through the winter.

You should exercise care when deciding how to landscape over a leach field for your septic system. You typically want lightweight materials that won’t damage the drain field’s perforated pipes. When adding plants to the area, select plants with shallow roots, such as grass or flower gardens. Trees with deep roots could damage the pipes in the field.

Mulch is widely available and affordable. You can find it online or at most local home improvement stores.
