Common Mistakes to Avoid
❌ Piling mulch on stems
Keep mulch 3-4 inches away from plant stems and tree trunks to prevent rot.
❌ Too thick application
Over 4 inches restricts water and air. Ideal depth: 2-3 inches for annuals, 3-4 inches around trees and shrubs.
Frequently Asked Questions

Bulk vs bags?
Bulk by cu yd is 30-50% cheaper for large areas. Bags convenient for small areas or hard-to-reach spots.
