How deep to spread
Two to three inches of mulch suppresses weeds and holds moisture; much deeper can smother roots. Keep mulch a few inches away from tree trunks and plant stems. One cubic yard covers about 108 sq ft at 3 inches, or 162 sq ft at 2 inches.
Bags or bulk
Bagged mulch usually comes in 2 cubic foot bags, so 13.5 bags make one cubic yard. Above about 3 yards, bulk delivery is usually cheaper than bags.
Frequently asked questions
