“Barrier Blend” is a native grass seed blend comprised of switchgrass, and is an easy way to establish a permanent visual barrier along any part of your property or in your pollinator garden. We’ve chosen 2 specific selections of tall growing native switchgrass for this blend, and a good stand will grow up to 7-10 ft tall. By using pure switchgrass seed you can use a wider range of herbicides if necessary to aid the establishment. Usually by year 3 you can have a super thick and tall stand of switchgrass that will come back year after year.
