1
Prune overhanging branches that prevent sunlight from reaching your yard. If
possible, remove and transplant trees and shrubs that block the sun.
2
Remove moss manually with a flail-type dethatching tool in mid-March to
through April--when moss is most vigorous--and dispose of it.

Attack remaining moss with a cryptocidal soap made for killing moss, applied
at a rate of 2 1/2 quarts per 1,000 square feet. Or make a natural moss-
killing spray by mixing a box of baking soda with 2 gallons of lukewarm
water and applying it to moss foliage with a spray mister. Pick up and
discard dead moss.
4
Use a shovel to turn over and aerate the soil that was under the moss, and
top dress it with a fine mix of topsoil or peat to improve soil quality.
5
Reseed in order to cover bare spots and prevent moss from returning. If your
yard still has spots where the sun doesn't reach, use shade-tolerant
grasses such as fine fescue--good in dry shade--and roughstalk bluegrass,
excellent for moist shaded areas.
6
Mow your new grass at the tallest recommended mowing height to encourage
deep rooting, healthy growth and maximum exposure of blades to sunlight.
7
Use a complete fertilizer with iron in the spring and fall to efficiently
control moss, improve soil quality and stimulate lush grass growth. To
prevent stains on concrete, apply fertilizer carefully and make sure to
contact moss foliage.
8
Control chinch bugs, which damage lawns and leave them susceptible to moss
invasion. Use an insecticide containing diazinon or chlorpyrifos for best
results.
