Orchardgrass

Orchardgrass is a productive, leafy forage grass used for pasture and conserved feed. It performs best on well-drained soils and works well in mixtures with legumes.

Dactylis glomerata · Cool-season perennial forage bunchgrass

Profile

Growth habit: Bunch-type grass without rhizomes or stolons.
Season: Begins growth early in spring.
Companion crops: Compatible with alfalfa, red clover, and other forage legumes.
Management: Suitable for intensive rotational grazing when properly managed.

Water & soil context

Moisture (VWC): Provide moisture in well-drained soil; avoid prolonged saturation.
Salinity tolerance: The USDA guide states that orchardgrass does not grow well in saline soils; no numerical threshold is supplied.
Drought tolerance: Penn State rates drought tolerance as moderate.

Editorial placement example, not a validated optimum or total rooting depth. Confirm the site's root distribution and soil horizons; multiple depths may be needed.

Irrigated sites can support orchardgrass, but high water tables and extended soil saturation are unsuitable.
