Frequently Asked Questions
How deep should mulch be?
Most garden beds need 2-4 inches of mulch. Around trees, keep it 2-3 inches deep and away from the trunk. Too much mulch can suffocate roots.
How many bags of mulch do I need?
Standard bags are 2 cubic feet. Divide your total cubic feet by 2 to get the number of bags. Bulk delivery in cubic yards is more economical for large areas.
Should I add extra mulch?
Add 5-10% extra to account for settling and irregular surfaces. Mulch compresses over time and will need topping up annually.
