How to Grow Forage Grass Mix (Timothy, Orchardgrass, Bromegrass)

Forage Grass Mix (Timothy, Orchardgrass, Bromegrass)

Phleum pratense, Dactylis glomerata, Bromus species

grass

A blend of three cool-season perennial forage grasses commonly used in pastures, hay fields, and erosion control. Timothy provides high nutritional value and palatability, orchardgrass offers drought tolerance and extended grazing seasons, and bromegrass contributes winter hardiness and soil stability. These species are often seeded together to create diverse, productive, and resilient grasslands.

Growing Conditions

☀️
Sun: Full sun, minimum 6 hours daily; 8+ hours optimal for maximum production
💧
Water: Moderate and consistent moisture; 15-20 inches annual rainfall or supplemental irrigation. Timothy and bromegrass tolerate cooler, wetter soils; orchardgrass handles drier conditions better
📏
Spacing: Broadcast seeding at 15-30 lbs/acre for mixed stands; individual plants establish 6-12 inches apart naturally inches
📅
Days to maturity: Grazing ready in 60-90 days from germination; full productivity in 1-2 years
🌱
Planting depth: Surface to 0.25 inches deep for small seeds; firm soil contact critical

Soil

Type: Well-draining loamy to clay loam soil; tolerates moderate moisture
pH: 6.0-7.5
Amendments:
Lime (if pH below 6.0) Phosphorus and potassium fertilizers Compost or well-rotted manure for organic matter Boron (if deficient)

Growth Stages

1

Germination & Seedling

3-6 weeks

Seeds germinate in 7-14 days under cool, moist conditions. Seedlings emerge with thin, grass-like leaves; vulnerable to competition and drought

Keep soil consistently moist without waterlogging. Control weeds aggressively. Avoid heavy grazing or traffic for 4-6 weeks. Ensure good seed-soil contact during establishment

2

Establishment & Tillering

6-12 weeks

Seedlings develop root systems and begin tillering (producing side shoots). Gradually forms dense turf. Root development reaches 8-12 inches

Light grazing (if livestock present) encourages tillering but avoid close clipping. Monitor for weeds. Apply nitrogen only after establishment if needed. Maintain consistent moisture

3

Vegetative Growth

Months 2-8

Rapid leaf and shoot development; dense stand formation. Plants accumulate biomass and nutrients. Orchardgrass may grow taller than timothy; bromegrass spreads via rhizomes

Rotational grazing or regular clipping maintains vigor. Remove deadstock and rank growth. Nitrogen fertilization (40-60 lbs/acre) supports growth. Manage moisture, especially during dry periods

4

Boot & Heading

3-4 weeks

Reproductive phase begins; seed heads emerge and develop within leaf sheath (boot stage) then extend (heading). Maximum forage quality typically 7-10 days before heading in timothy

For hay: harvest at boot to early-heading stage for peak nutrition. For pasture: graze before heading to maintain quality. Avoid cutting when wet to prevent disease. Each species heads at slightly different times in mixed stands

5

Seed Maturation & Dormancy

4-8 weeks, then dormancy

Seed heads mature and harden; plant energy redirects to reproduction. Growth slows in late summer. Cool-season species slow in heat; resume growth in fall

If harvesting for seed: wait until seed is hard and dry. For grazing/hay: utilize regrowth in fall or allow rest period. Avoid heavy use after seed set to allow plant recovery

Companion Planting

Plan your garden →

Plant with:

Legumes (Alfalfa, Red Clover, White Clover) Bird's-foot Trefoil Sainfoin Chicory Plantain

Avoid planting near:

Allelopathic plants (Black Walnut, Eucalyptus) Heavy shade-casting trees (blocks light needed for grass) Competitive aggressive weeds (Quackgrass, Canada Thistle in early establishment phase)

Common Pests

  • Scout for dark frass and wilting; use insecticidal soap or neem oil if populations exceed economic threshold; encourage natural predators

  • Maintain diverse plant structure; use rotenone or spinosad in severe infestations; manage moisture to reduce egg-laying sites

  • More common in seedlings; encourage strong establishment; insecticidal treatments rarely warranted in established stands

  • Less problematic in cool-season grasses; maintain adequate moisture and fertility to reduce stress

Uses

🍳

Livestock Forage & Nutrition

Culinary

High-quality hay and pasture for dairy cattle, beef cattle, sheep, and horses. Timothy is particularly valued for equine nutrition due to its palatability and balanced calcium-phosphorus ratio. Mixed stands provide diverse nutrient profiles with extended grazing seasons. [source]

🏠

Hay Production

Household

Mixed stands are ideal for commercial hay operations. The combination provides consistent yield, extended harvest windows, and improved storage quality. Often baled and sold for livestock feed, pet bedding, or animal litter. [source]

🏠

Pasture & Grazing Management

Household

Creates productive pastureland for rotational or continuous grazing systems. The diversity of species provides consistent forage throughout the growing season as different grasses peak at different times, extending the grazing window. [source]

🦋

Wildlife Habitat & Food

Wildlife

Provides cover and food for grassland birds, pollinators, and beneficial insects. The structural diversity and seed production support diverse wildlife communities and are used in conservation grassland plantings. [source]

🏠

Erosion Control & Soil Stabilization

Household

Deep root systems prevent soil erosion on slopes and in riparian zones. The dense turf stabilizes soil and improves water infiltration. Often used in conservation plantings along waterways, ditches, and disturbed areas. [source]

Harvest Tips

For hay: Cut at boot to early-heading stage (typically late May to early June in northern zones) when forage quality is highest and before seed set. Use a mower-conditioner for faster drying. For pasture: Use rotational grazing with 3-4 week recovery periods; graze to 2-3 inches residual height to maintain plant vigor. Multiple harvests possible: spring, early summer, and fall regrowth. Seed harvesting requires specialized equipment; seeds mature sequentially across the mixed stand

Fun Facts

  • 🌱 Timothy grass is named after Timothy Hanson, an 18th-century colonial farmer who popularized its cultivation in North America, though the species originated in Europe and Asia.
  • 🌱 Orchardgrass (also called cocksfoot) thrives in partial shade better than most forage grasses, making it valuable in silvopasture systems with trees.
  • 🌱 Bromegrass can spread via underground rhizomes, gradually creating a more solid sod over 2-3 years, which improves erosion control but may eventually crowd out timothy if not managed with rotational grazing.
