Frequently Asked Questions
How deep should mulch be applied?
2–4 inches is ideal for most garden beds. 2 inches controls weeds adequately; 3–4 inches provides better moisture retention. Avoid piling mulch against tree trunks — keep a 6-inch gap.
How many cubic yards of mulch do I need?
Multiply area (sq ft) by depth (inches) then divide by 324. For example: 500 sq ft at 3 inches deep = (500 × 3) / 324 = 4.6 cubic yards. One cubic yard covers 324 sq ft at 1-inch depth.
How much does mulch cost?
Bagged mulch runs $3–$8 per 2-cubic-foot bag. Bulk delivery averages $30–$60 per cubic yard for wood mulch, $50–$90 for premium types like dyed or rubber mulch. Delivery fees add $50–$150.
