Volume = L × W × (D/12) (ft³)
Cu Yards = Volume ÷ 27
Bags = Volume ÷ bag size (cu ft)
2–3 inches for established beds. 4 inches for new beds. Never more than 4 inches — it can suffocate roots.
At 3 inches deep: ~108 sq ft. At 2 inches: ~162 sq ft. At 4 inches: ~81 sq ft.
13.5 bags per cubic yard (27 ÷ 2 = 13.5, round up to 14).
Spring (after soil warms) or fall (before freeze). Avoid mulching when soil is wet.
