Ways To Split Ornamental Grasses
With time, ornamental grasses can begin to thin out in the center. When this happens, it is best to split the grasses. Most types of grasses are divided into either cool or warm season grasses. Cool season grasses are those that emerge from dormancy in late winter and early spring, blooming in late spring or early summer. Growth of the plant slows when temperatures exceed 75 degrees Fahrenheit. When temperatures drop in autumn, the grass comes back to life for a short time, then turns brown and goes dormant for the winter. Here are several ways to split ornamental grasses. Shear off last year’s growth so that the plant stands 4 to 5 inches tall. It is best to do this in early spring before the growing season takes off.
Decide how many plants you will be splitting the grass into. Split the grasses by angling the spade directly down into the clump. Decide on the size you want the new grass to be and then make another cut into the grass. Lift the new portion of the grass out and replant it in the new location. Place at least three inches of mulch around the new transplant and make sure to give it a heavy watering to allow it to begin to root.
