In the Spring and Summer mulch is a great weed suppressor and it also retains moisture. A 3” layer of mulch will suffice during the spring and summer, but in the winter a 2” layer is more than enough.
Don’t know how to calculate mulch?
Here’s a quick formula: Calculate the square footage of your bed Multiply by the depth (in inches) you want (2” or 3") Divide by 324 (324 is how many cubic yards in 100 square feet)
For example if your bed measures 10 x 15: 10 x 15 = 150__150 x 2 (depth) = 300 300 / 324 = .92 (round off to whole number) = 1 yard
When we mulch, we like to use mulch that's free of any color enhancements like sweet peet or natural brown mulch.
