How much mulch do I need?

Multiply your bed's square footage by the mulch depth in inches, then divide by 324 to get cubic yards. For example, 200 sq ft at 3 inches deep needs about 1.85 cubic yards. Use the calculator above to add multiple beds at once.

How many bags of mulch are in a cubic yard?

A cubic yard equals 27 cubic feet. That's about 13.5 bags of the standard 2-cubic-foot size, or 9 bags of the 3-cubic-foot size. Above roughly 2 cubic yards, buying mulch in bulk is usually cheaper than bags.

How deep should mulch be in Florida?

Two to three inches is ideal for Florida beds. Less than 2 inches won't suppress weeds; more than 3-4 inches can hold too much moisture against plant stems in our humidity and lead to rot. Keep mulch a few inches off trunks and stems.

How much area does a cubic yard of mulch cover?

One cubic yard of mulch covers about 162 square feet at 2 inches deep, or about 108 square feet at 3 inches deep.

How the mulch calculator works

Cubic yards = (square feet × depth in inches) ÷ 324. One cubic yard covers about 162 sq ft at 2″ or 108 sq ft at 3″. A standard 2-cu-ft bag covers roughly 12 sq ft at 2″, and there are about 13.5 of those bags in a cubic yard.

How deep should mulch be?

In Southwest Florida, 2–3 inches is the sweet spot. Thinner than 2″ won't hold back weeds; thicker than 3–4″ traps too much moisture against stems in our humidity and invites rot. Always pull mulch a few inches back from trunks.

Bags or bulk?

Bags are convenient for one or two beds. Once you're past ~2 cubic yards, bulk delivery is cheaper and faster — and you're not hauling 27 bags.
