Frequently Asked Questions

How deep should mulch be?

A standard depth is 2-3 inches. This allows for weed suppression and moisture retention without suffocating plant roots. Piling it too high ('Volcano Mulching') can kill trees.

What is a Cubic Yard?

A Cubic Yard is a volume of 3ft x 3ft x 3ft. It is the standard unit for bulk delivery. One cubic yard covers roughly 100 sq ft at 3 inches deep.

How much does a yard cover?

At 3 inches deep, 1 yard covers ~108 square feet. At 2 inches deep, it covers ~162 square feet.
