The goal of pruning is to remove old foliage. This is done mostly in the fall but we prune ours in the spring to enjoy a contrast during the winter, wild birds appreciate the seeds and shelter also! Leaving the foliage intact can help protect the crown of the grass from cold and moisture, reducing the chance of winter rot.
By the time the old growth starts to lose its appeal in early spring we cut the plants down to 4-6 inches above the ground for the new growth.
Below are some pictures and additional information about pruning and dividing clumps.
Tying up the stalk
First we tie up the grass top for easier cleanup.
For smaller grasses handheld pruning or grass shears work just fine.
Larger grasses need more powerful tools, such as electric shears or power trimmers. Use eye protection if needed. Some grasses have sharp edges.
Clipping grass
Grasses that are not cut down in the fall may take up to 3 weeks longer to sprout in the spring.
Old foliage shades the crown of the clump keeping it colder longer.
Clip grass down to 4-6 inches above the ground.
In this picture dated March 30th, new growth is evident.
Division depends on the spacing and visual appearance of the plants as well
as the overall health. Plants suffering from die-out in the center should be
divided to improve appearances. Division is done in the spring before growth
resumes or in the late summer or fall after the growing season. Plants that
bloom late could be divided in the spring.
