Growing and Maintenance Tips:

Grows best in a moist soil, in full sun, is tolerant of a dry soil in partial shade and can be used for slope stabilization. It should be pruned back to 10 cm above ground level in early spring.

Additional Notes about Switch Grass:

Native to Ontario

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.
