Douglas Fir bark
- As a minimum to aid in weed control, and for proper insulation of plant roots we recommend that you apply 3 to 4 inches of bark. - It is best to spread bark in early spring or early fall before heavy weed growth periods. - There after apply 1 to 2 inches each year after to maintain proper depth and a fresh, clean appearance. - Additional mulch may be needed to reduce erosion of soil.
