Moss invades thin or bare areas of the lawn. It does not grow in a vigorous lawn, and prefers shade. Moss is encouraged by poor fertility, poor drainage, compacted soil, shade, and high acidity. Moss plants sprout from spores and fill in bare or thin areas.
Moss may be removed by hand or power raking. Reduce shade by pruning nearby trees. Correct soil compaction and improve drainage. Test the soil pH and correct it if necessary. Follow recommended lawn care practices to promote a healthy, vigorous lawn.
