Switchgrass offers additional environmental benefits such as helping to improve water quality and wildlife habitat, helping to reduce carbon emissions through carbon sequestration in the soil, and serving as a replacement for fossil fuel… has a high germination (greater than 60 percent) and low dormancy (less A thick stand of Switchgrass makes excellent winter and early spring wildlife cover because of its ability to remain in an upright position when covered with snow or ice. multiple harvests of switchgrass can reduce future yields. Alamo performs well on a wide range of soils from clay to very fine sand. If you’ve spent any time at all seeding native plants in the past, you will have run into the “Pure Live Seed” qualifier for seeding rates.

It is vital to not plant switchgrass seeds any deeper than ½ inch. Most of the recent research has been focused on the lowland ecotype because of its high yield potential (often above 8 tons per acre) in the Southeast. rationale is since seed dormancy declines over time, the older, dormant To plant seedlings, Work the soil to a depth of several feet, to accommodate the length of the taproot.
