Our rhizomes grow at the following rates for the first three years:
- Year 1 growth is 6 to 7 feet in height and 12 inches in diameter
- Year 2 growth is denser and 6 to 10 feet in height, 24 inches in diameter
- Year 3 growth is even more dense, over 14 -16 feet in height and 36 inches in diameter
They are considered mature after the third year. From year three on, your rhizomes will continue to become more and more dense. However, individual grasses maintain 36-inch widths.
What type of soil is required for silver grass?
You can grow our rhizomes in literally any type of soil, except any soil in standing water and the nearly all-sand soil that is found along some riverbeds.
