Although for some gardeners moss may be an ornamental feature, others find moss to be a nuisance. Moss is a simple plant with no roots that grows in a dense mat. Moss may be present in damp, shady areas of a lawn where grass does not grow well. The sparse vegetation allows moss to establish a foothold in the lawn, but moss does not kill existing vegetation. Fortunately, removing moss from your lawn is a matter of removing the conditions that cause moss to thrive.
Prune surrounding vegetation to allow sunlight into the mossy area. Since moss prefers shade, this will cause it to dry up and die.
Rake the moss where it lies to pull it up from the ground.
Seed the bare area where moss used to be with grass seed to crowd out moss.
Mulch grass seed with compost to a depth of ¼ inch.
Water mulch to germinate grass seeds. Keep soil damp to the consistency of a wrung out sponge until seeds are established.
