Bagged mulch is handy for small beds; bulk by the cubic yard is cheaper past about 10 bags. One cubic yard equals roughly thirteen 2 ft³ bags.
Mulch settles, so a fresh 3 in layer thins over the season. Top up rather than piling it against trunks and stems.
How it works

Measure the bed
Enter the length and width of the bed or area you are mulching.

Set the depth
Two to three inches refreshes a bed; three to four suppresses weeds.

Frequently asked questions
- How much mulch do I need?
- Multiply length by width by depth in feet, divide by 27 for cubic yards, or by the bag volume for bags. The calculator does both so you can compare.
- How many bags of mulch in a cubic yard?
- A cubic yard is 27 cubic feet, so it holds about thirteen 2 ft³ bags or nine 3 ft³ bags. Bulk is usually cheaper past roughly ten bags.
- How deep should mulch be?
- Two to three inches is enough for most beds; three to four blocks weeds. Keep it off trunks and stems and top up as it breaks down.
- How accurate is the mulch amount?
- The cubic yards are exact for the bed size and depth you enter. Bark, wood chip and compost pack down differently and mulch settles over a season, so order a little extra and top up as it breaks down.
