How to Take Care of Blue Fescue


Blue fescue is the most eye-catching variety of cool season fescue grasses. And like its hardy cousins, this ornamental grass is drought-resistant and virtually impervious to disease and pests. When grown in a sunny spot with full sunlight and well-drained soil, it can be quite independent. However, to grow to its full potential, blue fescue does need care and attention once or twice a year. And with no more than this minimal commitment, your blue fescue will grow into a full and attractive plant that will accent your garden for years to come.

Step 1

Spread a three inch layer of organic mulch around the base of your blue fescue.

Step 2

Water your blue fescue. For the first three weeks after it has been planted in your yard, your blue fescue will need water whenever the soil dries out. After that, only water it during the hottest and driest times of the year to prevent the foliage from turning brown.

Step 3

Cut your blue fescue back to 3 inches in height in late winter or early spring when new growth is sprouting. Then, clear the center of the plant by removing any dead foliage.

Step 4

Prune blue fescue's flowers as soon as they appear. This will force the plant to redirect its energy to growing new foliage.

Step 5

Divide your blue fescue once every 2 to 3 years, when the center of the plant begins to die.This will prolong its life and maintain its global shape. Blue fescue can be divided at any time during the growing season. Split the clump into sections and discard the center of the clump. Replant the more vigorous blue portion around the edge at the same level it was growing.
