How much mushroom compost should be used for establishing roadside vegetation?
The best approach would be to apply mushroom compost uniformly and evenly at a one to three inch thickness (three to nine cubic yards per 1,000 square feet) on the surface of the intended site, and then incorporate into the existing soil below. Next, seed or transplant the desired vegetation. For example, with turfgrass, sow the grass seed uniformly at a rate recommended for the turfgrass species used, and water thoroughly. For sites with steep slopes, erosion blankets or netting may be helpful to reduce further the possibility of soil erosion.
