Used by Wildlife:
Prairie June Grass is considered a fair to good forage for elk throughout the year, and is desirable forage for deer and antelope in the spring and early summer.
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.
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.
Long Term Care:
May be vulnerable to some insects such as the striped flea beetle which will cause the leaf tips to wilt
No significant insect or disease problems. Occasional problems include rusts, leaf spots and blights.
No serious problems
A cool-season grass, late-summer dormancy.
