Mulch Depth Recommendation
Frequently Asked Questions
How deep should I apply mulch?
For most landscaping applications, a depth of 2-4 inches of mulch is recommended. Apply less (about 1-2 inches) around shallow-rooted plants and more (3-4 inches) for weed suppression in other areas. Never exceed 4 inches as this can prevent water from reaching plant roots and cause rot issues.
How many bags of mulch are in a cubic yard?
A cubic yard of mulch equals approximately 13.5 bags of mulch (assuming standard 2 cubic foot bags). For 3 cubic foot bags, a cubic yard would equal about 9 bags.
How often should I replace mulch?
Organic mulches like wood chips or bark typically need refreshing annually, usually in spring. You don't always need to remove old mulch - often you can add a thin new layer (1-2 inches) on top of existing mulch that has decomposed and settled.
