How to Grow orchardgrass
Dactylis L.
Orchardgrass (Dactylis glomerata) is primarily a forage and turf grass. While rarely grown as an ornamental, standard green-form orchardgrass can be used in borders or containers for its upright, functional habit and compact panicles. Striped or variegated cultivars are uncommon in cultivation and not standard ornamental recommendations. Compared to popular ornamental grasses like miscanthus, feather reed grass, or fountain grass, orchardgrass offers a more utilitarian appearance but can be useful in mixed plantings where a practical grass is desired.
soil preparation
Orchardgrass performs well in potting soil with excellent drainage and aeration. While specific pH requirements are not detailed in historical sources, prepare well-draining beds or containers to prevent waterlogging. For border plantings, amend soil to ensure good structure that supports dense, stately growth suitable for massing.
planting steps
Select Green-Form Orchardgrass
If growing orchardgrass ornamentally, use the standard green form (Dactylis glomerata). Striped varieties exist but are uncommon and not widely available in the nursery trade. Green forms are the practical choice for containers or borders.
Tip: Orchardgrass is hardy in USDA zones 3–9 and establishes quickly from seed or divisions in spring through early autumn
Prepare Container or Border Bed
For containers, use pots with drainage holes and well-draining potting soil. For borders, prepare beds with adequate drainage and space plants 12–18 inches apart for air circulation. Orchardgrass tolerates average soil and does not require rich amendments.
Tip: As a forage grass, orchardgrass is undemanding and performs better on modest fertility
Plant and Water Through First Season
Plant in spring or early autumn. Water regularly during the first growing season (spring through early summer) to establish a deep root system. Once established, orchardgrass tolerates moderate drought but thrives with consistent soil moisture.
Tip: Active growth begins in spring; seed heads appear by late May or June in most temperate regions
watering
Maintain consistent moisture appropriate for ornamental grass growth. Avoid waterlogging or allowing soil to completely dry. Monitor soil moisture regularly and water when the top inch becomes dry to the touch. Frequency depends on temperature, humidity, and whether plants are containerized or in-ground.
feeding & fertilizer
Orchardgrass, as a forage grass, requires minimal supplemental nutrition. For potted plants, apply a balanced fertilizer (10-10-10 equivalent) once at planting. For border plantings, a single early-spring application supports the season's growth. Avoid excessive nitrogen, which promotes soft, rank growth and increases lodging risk in containers.
pruning & training
Orchardgrass requires no regular pruning. Cut back established plants to 2–3 inches in late winter or early spring before new growth emerges. If harvesting seed heads for dried arrangements, time cutting after panicles have fully formed (typically June in temperate zones) but before seeds shatter. The compact structure of orchardgrass panicles means dried material lacks the airy visual impact of premium ornamental grasses. To dry, hang seed heads upright in a warm, dark location for 2–3 weeks to preserve natural color and prevent bleaching.
harvesting
Orchardgrass produces compact, dense seed heads in late May through June, with timing varying by region. For decorative use, cut stems after panicles have fully emerged but before seeds shatter. Cut cleanly at the base using sharp scissors or pruners. Expect compact, tight panicle structure rather than the airy, flowing forms of premium ornamental grasses. Fresh or dried seed heads can be used in arrangements.
storage & preservation
After harvesting, dry completely in the dark while keeping stems upright—this is critical for preserving color and form. Dark drying prevents bleaching and maintains the natural elegance of the grass. Properly dried orchardgrass stores indefinitely in cool, dry conditions in a vase or container. For creative projects, dried material accepts dyes and bleach treatments well, offering flexibility in final presentation.
common mistakes to avoid
- ✗Expecting refined ornamental-quality appearance: Orchardgrass is a forage grass with a utilitarian look and lacks the visual refinement of dedicated ornamental grasses like miscanthus or feather reed grass
- ✗Overfeeding in containers: Excessive fertilizer causes rank growth and lodging; use a single spring application only
- ✗Harvesting too late: Once seeds shatter, the panicle disintegrates; harvest when panicles have matured but before seeds drop
