Mulch Calculator
Mulches provide a protective layer over the root system of plants, which protects the plants from harsh weather conditions in the summer and winter months. This protective layer not only provides a barrier to enhance the moisture retention within the beds below (improves moisture retention up to 75%), but it will also add nutritional value back into the soil as the mulch itself decomposes.
Application:
Apply 1-2 inches in depth when adding the mulch for appearance. Apply 3-4 inches in depth when controlling moisture, protecting the plants, or when attempting to control weeds.
