Blue fescue is an attractive, blue-grey ornamental grass that is quite hardy despite its delicate-looking beauty. It is drought, disease and pest resistant and, once planted in the ground, it can generally be left alone. However, while your blue fescue has few needs, one of the most important of those is a periodic trim. Trimming your blue fescue stimulates its growth and helps maintain its signature global shape.
Trim each clump of blue fescue down to 1/3 of its original size every spring to maintain its shape and encourage it to produce new blades. Do this at the beginning of the growing season when the plant produces new growth.
"Spring clean" your blue fescue by trimming away any dead or browning blades and raking out any debris in the interior of the clump.
Prune blue fescue's flowers as soon as they appear. This redirects your blue fescue's energy into filling itself out.
