The Northwind plant is a native grass that is grown as an ornamental feature in gardens and prairie settings. The grass is also referred to as switch grass and is hardy in USDA zones 2 through 9. Northwind grass grows to a height of 5 feet with a spread of 2 to 3 feet and produces olive green wide blades of grass that grow upright. The grass produces a plume of seed heads in September.
Select a planting location for the Northwind grass that has full to partial sunlight and a soil that drains well. The grass will grow in a dry soil but prefers moist sand or clay-based soil.
Water the grass plant during the growing season when the rainfall amounts are less than 1 inch per week. The plant is tolerant of both dry and wet conditions as long as the roots are not saturated in standing water.
Fertilize Northwind grass plants with a low-nitrogen fertilizer during the growing season once they become established. High nitrogen can burn young growth and inhibit the production of beneficial mycorrhizal fungi in the soil.
Burn the grass every 3 to 5 years with a controlled fire just before new growth begins in the spring. This will rejuvenate the grass and increase the plant's vigor.
Cut or mow the grass to the ground in late fall. The grass will grow back in spring once the soil begins to warm.
Propagate Northwind grass by collecting seeds before they drop from the plant. Plant the seeds directly into the ground at a depth of 1/4 to 1/2 an inch. The seeds will germinate and sprout in the spring once the ground warms above 68 degree F. The grass can also be divided by breaking the root ball into sections; however it may be difficult to break apart the shallow tough roots.
