Is a Switch Grass Plant Invasive?
- Without proper management, switchgrass is likely to spread beyond the desired area. For this reason, it is considered an invasive weed, according to the U.S. Department of Agriculture's Natural Resources Conservation Service.
- Switchgrass is slow to establish itself in a new area. This gives you time to remove the switchgrass from areas outside of the desired plot of land. Once it has established, switchgrass has a deep root structure -- almost as deep as the plant is tall -- that will be much more difficult to clear.
- Switchgrass benefits from controlled burning every few years, but you will want to contact your state's department of natural resources for information on prescribed burns. This will help control weeds and reduce the risk of switchgrass spreading to other areas.
