Growing and Maintenance Tips:

Mosquito grass can be grown in full sun or light shade in a wide range of soil types, however, it does not tolerate poorly drained, wet areas. It can be used as turf, and mowed regularly. If allowed to grow naturally, prune in early spring to make room for new growth.

Additional Notes about Blue Grama:

Native to Ontario and much of North America.

Warm Season Grasses: These grasses are much slower starting in the spring. They do not push new growth until temperatures warm in early to midsummer. They flower later in the summer or fall with most blooms remaining into the winter. Most warm season grasses tolerate heat, humidity and drought; some even thrive in these conditions.
