How It Works

Mulch is bought by the cubic yard, and the right quantity depends on three things: the area you're covering, the depth you want, and the type of mulch itself. Pinning those down keeps a 2026 landscaping budget honest, whether you're hauling home bags or scheduling a bulk delivery.

Volume comes first, in cubic feet, by multiplying Length x Width x Depth. Dividing that figure by 27 turns it into cubic yards. When you ask for a bag count, the total cubic yards get divided by the average yield per bag for your chosen mulch, for instance 2 cubic feet per bag of standard shredded hardwood, which works out to 0.074 cubic yards per bag.

Careful measurement up front beats rounding generously, since padding the area too much leaves you with surplus you didn't need. Depth is where coverage usually falls short: aim for at least 2-3 inches if you want real weed suppression. Finer mulches also settle and compact more than coarse ones, so a small buffer is worth folding in for those.

Example: Mulching a rectangular garden bed

  1. 1 Input: A garden bed is 20 feet long and 10 feet wide. You want a mulch depth of 3 inches (0.25 feet) using shredded hardwood mulch (2 cubic feet per bag).
  2. 2 Calculation: Area = 20 ft x 10 ft = 200 sq ft. Volume = 200 sq ft x 0.25 ft = 50 cubic feet. Cubic yards = 50 / 27 = 1.85 cubic yards. Bags needed = 1.85 cubic yards / 0.074 cubic yards/bag = 25 bags.
  3. 3 Result: You will need approximately 1.85 cubic yards of shredded hardwood mulch, which equates to about 25 standard 2-cubic-foot bags.
  4. 4 Context: For bulk delivery, you would order 2 cubic yards to ensure full coverage. If buying bags, you'd purchase 25 bags, costing around $150-$200 total in 2026, depending on the supplier and brand.

Frequently Asked Questions

How many cubic yards of mulch do I need?
Measure your area in square feet, multiply by desired depth in inches, then divide by 324. For example, a 500 sq ft garden bed with 3 inches of mulch needs (500 x 3) / 324 = 4.6 cubic yards.
Is it cheaper to buy mulch in bags or bulk?
Bulk mulch is almost always cheaper. Bagged mulch costs roughly $4-7 per 2 cubic foot bag ($55-95 per cubic yard), while bulk delivery runs $25-45 per cubic yard. Bulk delivery makes sense for anything over 3-4 cubic yards.
How deep should I apply mulch?
Apply 2-3 inches of mulch for most garden beds and around trees. Going deeper than 4 inches can suffocate roots and trap excess moisture. Keep mulch 3-6 inches away from tree trunks and plant stems to prevent rot.
