Lighting and Temperature

F. glauca is a sun-loving grass that grows best in full sun to partial shade. It will tolerate some shade, but it will not flower as profusely in shady areas.

This grass prefers cool weather and does not do well in hot, humid summers.

In very hot climates, F. glauca may go dormant during the summer months and should be watered only enough to keep the roots alive until cooler weather returns in the fall.

If you live in an area with cool summers, you can cut back the foliage of F. glauca after it flowers in early summer to encourage fresh growth.


Soil, water, and sun requirements for blue fescue are similar to those of other ornamental grasses. It prefers full sun but will tolerate some shade, and it needs well-drained soil.

Blue fescue is drought tolerant once it is established, but it will perform best with regular watering.


Fertilizer is not necessary for blue fescue, but if you choose to use it, a slow-release fertilizer is best. Apply it in early spring before new growth begins.

To promote compact growth and prevent legginess, shear the grass in late spring or early summer.


Pruning is an important part of keeping your blue fescue grass looking its best. You’ll want to prune it back in early spring, before new growth begins.

To do this, simply cut the grass down to about six inches using sharp shears.


Blue fescue grass is drought tolerant, so it doesn’t need a lot of water. In fact, too much water can actually harm the plant.

It’s best to let the soil dry out between watering. During periods of extended drought, you may need to give the plant an occasional deep watering to help it survive.


Size and shape vary depending on the cultivar, with some selections staying neat and compact while others can become quite leggy.


Flowering takes place in May and June. The blue fescue grass produces light yellow flowers that turn into fluffy, silver-white seed heads later in the season.

The entire plant turns a beautiful shade of bronze in the fall before dying back for the winter.

Common Problems With Blue Fescue

Gardeners in hot climates who are growing blue fescue may encounter a different issue with the plant. Due to high humidity and heat, the above-ground growth may die off in the summer.

If this happens, you should give the plant a “haircut.” By cutting back the dead growth, you will improve the plant’s appearance and help it to regrow more quickly.

In most cases, the plant will return to normal as the weather improves. However, if the problem persists, it is possible that the plant is not receiving enough water or that it is suffering from a disease.

In these cases, it is best to consult with a gardening expert to determine the cause of the problem and find a solution.

Propagating Blue Fescue

Blue fescue is a beautiful, low-maintenance plant that is perfect for adding color and texture to any garden.

One of the most appealing features of blue fescue is its ability to spread and fill in empty spaces. However, over time, a single clump of blue fescue will begin to look tired and crowded.

When this happens, it is time to split the plant and replant it. Splitting is a simple process that can be done with a shovel or garden trowel. First, remove the plant from the soil.

Then, use a spade or pruners to cut the clump in half. Remove any brown pieces, and replant the clumps as new plants, spacing them 8 to 10 inches apart.

Water the roots well and apply soil if necessary. With a little care, your blue fescue will continue to thrive for many years to come.
