Spring is when most people order mulch, and it is easy to guess wrong. This checklist helps you order the right amount the first time.
Step 1: Measure your beds
Measure the length and width of each bed in feet. For curved beds, use the average width. Multiply length by width to get square feet, then add the beds together.
Step 2: Pick a depth
Two to three inches is the usual depth for flower beds. Use 2 inches to refresh mulch that is already there. Use 3 inches for new beds or to block weeds. Going deeper than 4 inches can hold too much water around plants.
Step 3: Convert to cubic yards
Multiply square feet by the depth in feet, then divide by 27. Here is what that looks like at 3 inches deep:
- 100 square feet needs about 0.93 cubic yards
- 250 square feet needs about 2.31 cubic yards
- 500 square feet needs about 4.63 cubic yards
- 1,000 square feet needs about 9.26 cubic yards
Or skip the math and use the mulch calculator.
Step 4: Decide bulk or bagged
A cubic yard is about 13.5 bags of 2 cubic foot mulch. Under about 2 yards, bags are often easier. Above that, bulk is usually cheaper once you add delivery. Use the price estimator to compare your quotes.
Step 5: Add a little extra
Order about 5 to 10 percent more than you calculate. Leftover mulch is easy to use later, but a short delivery means another trip.
