Cutting back purple fountain grass is a crucial step in maintaining its health and appearance. It's best to cut back the grass in late winter or early spring, before new growth begins.

To determine the right time for cutting back, look for the grass's natural shedding process, which typically occurs in late winter. This will give you a clear indication of when to prune.

Cutting back the grass too early can lead to new growth, which may be damaged by frost. Wait until the danger of frost has passed to ensure the new growth will be healthy.

Cut the grass back to about 6-8 inches from the ground to promote new growth and prevent the plant from becoming leggy.
