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:

Insect Pests:

Grasshopper

Wildlife Pests:

Diseases:

Environmental Problems:

Indian ricegrass establishes slowly and new seedings should not be grazed until at least late summer or fall of the second growing season. New stands should not be grazed until the plants are reproducing by seed. Indian ricegrass benefits from grazing use

Landscape Problems:

Care Comments:

This species should be seeded with a deep furrow drill at a depth of 1/2 to 1 inch on medium to fine textured soils and 1 to 3 inches on coarse textured soils. A deeper planting depth puts the seed in contact with moist soil conditions, which aids in the
