A gardener must have come across this question when caring for the lawn. An initial estimate suggests that 2 cubic feet of mulch at a 2″ depth will cover 12 square feet.
The mulch coverage is influenced by the mulch type, and the depth at which the mulch is being installed.
Mulch is a wonder worker for the garden by holding in moisture and minimizing fluctuations in soil temperatures.
Determining how much mulch would be enough, its coverage, and its depth is very unsettling for a newbie.
The estimate comes easily for a landscaping professional, who is installing mulch from time to time, without any calculations. Online Mulch calculators are of great help for beginners in deciding on mulch coverage. Here is an easy-to-follow chart to help you decide how many bags of 2 cubic feet of traditional mulch you will need for a 10×10 area:
| Depth of mulch | One 2 Cubic Foot Bag (wood mulch) Covers | # of 2 Cubic Foot Bags Needed for a 10'x10' area |
|---|---|---|
| .5” | 48 sq feet | 2.08 bags |
| 1” | 24 sq feet | 4.16 bags |
| 2” | 12 sq feet | 8.3 bags |
