How it's calculated
Volume = length × width × depth Weight = volume × density 1 cubic yard = 27 ft³ Bags = volume ÷ bag size, rounded up
Works out the mulch to cover a bed to a given depth, as loose volume, as a count of bags and as a weight. 5–10 cm (2–4 in) is the usual depth; keep it away from stems and trunks. Bag sizes vary, so use the size on the bag.
