Examine the snake plant for unhealthy foliage, which may appear discolored or may be falling away from the plant horizontally. Healthy foliage grows vertically and has deep, variegated color.
Trim away the unhealthy foliage with pruning shears or scissors. Cut off the leaves from the base of the plant. Do not partially trim leaves, because the snake plant may respond to this injury by stopping its growth. Pruning from the base will cause energetic growth, making the plant appear fuller, or "bushier."
Discard the foliage in a basket or bag. Never leave plant refuse around the base of a plant -- it looks untidy and can cause disease.
