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.
