Piling mulch against tree trunks causes rot, pest problems, and tree death. Keep 3-6" gap.
Over 4" prevents water and air from reaching soil. Stick to 2-4" for most applications.
Under 2" won't suppress weeds or retain moisture effectively. Minimum 2" recommended.
Measure carefully and use our calculator. Extra mulch wastes money and storage space.
Some mulches harm certain plants. Research compatibility before purchasing.
Avoid dyed or rubber mulch near vegetable gardens. Use natural organic options instead.
