SEASONAL CARE

Spring Care:

Cut back the foliage to about 4-6 inches in the spring before growth resumes. When foliage is removed, spring growth will begin earlier. Old foliage left on the plant can delay the crown?s warming and subsequent growth by as much as 3 weeks.

Summer Care:

Fall Care:

Grasses do not need to be cut down before winter. In fact, they are attractive when left standing and the foliage helps to insulate the crown of the plant.

Winter Care:

Long Term Care:

May self-seed.

Insect Pests:

May be vulnerable to some insects such as the striped flea beetle which will cause the leaf tips to wilt

Wildlife Pests:

Diseases:

No significant insect or disease problems. Occasional problems include rusts, leaf spots and blights.

Environmental Problems:

Landscape Problems:

No serious problems

Care Comments:

A cool-season grass, late-summer dormancy.
