alternatives to pesticides - weeds - moss
Moss is a natural part of the Pacific Northwest’s native groundcover. If your lawn has moss, consider leaving it there or allowing it to spread in planting beds to form an attractive groundcover. It prefers shade, moisture, and poor acid soils.
Correct the conditions that encourage moss to grow. Water infrequently but deeply, making sure that the water is penetrating and not running off. Proper aeration and thatching of lawns will help air flow. Do not apply water faster than the soil can absorb it. Soil should be limed and fertilized to encourage the growth of desired plants or turf. If trees shade an area, consider pruning them to introduce more sunlight.
Rake moss out of lawns.
Least-toxic chemical control
Apply an herbicidal soap or an iron-based product that turns the moss black as it dies. Keep these products off concrete, as they will stain.
