Find how much mulch you need for your garden bed
Frequently Asked Questions
Multiply your bed's area by the desired depth (converted to feet), then convert to cubic yards by dividing by 27. Most beds use a 2-4 inch depth.
One cubic yard equals 13.5 standard 2-cubic-foot bags. Above about 1 cubic yard, bulk delivery is usually cheaper than buying bags.
2-4 inches is standard for most garden beds. Less than 2 inches doesn't suppress weeds well; more than 4 inches can smother roots and hold too much moisture.
No — the volume needed only depends on area and depth. Mulch type only affects the estimated weight (density varies from about 8 lb/cu ft for pine needles to 65 lb/cu ft for rubber mulch) and price.
