Growth Stages

1

Fall Germination & Establishment

4-8 weeks

Seeds germinate and develop root systems and initial leaf growth in fall before winter dormancy

Plant in late September to early October in zone 5; ensure soil moisture for germination; avoid waterlogging; established plants enter dormancy as temperatures drop below 40°F

2

Winter Dormancy

3-4 months

Plants remain dormant under snow and cold, relying on developed root systems for survival

No active care needed; snow cover provides insulation; Garrison's cold hardiness allows survival of sub-zero temperatures; good drainage prevents winter kill from ice encasement

3

Spring Growth & Tillering

4-6 weeks

As soil warms in spring (March-April in zone 5), plants rapidly resume growth, producing multiple shoots (tillers) from base

Apply nitrogen fertilizer in early spring as growth resumes; monitor for spring pests and diseases; ensure adequate moisture during this growth phase; weed management critical

4

Boot to Heading

3-4 weeks

Plants elongate rapidly, flower buds form within the flag leaf sheath, then heads emerge with flowering spike visible

Monitor for Fusarium head blight and powdery mildew; ensure adequate potassium levels; minimize excess nitrogen to prevent lodging; maintain consistent moisture

5

Grain Fill & Maturity

4-5 weeks

Pollination occurs, kernels develop and fill with starch, plant yellows and dries down; ready for harvest when moisture content drops to 12-14%

Reduce watering to encourage drying; monitor grain moisture regularly; harvest when kernels are hard and cannot be dented by fingernail; time harvest to avoid rain if possible

Companion Planting

Plan your garden →

Plant with:

Hairy vetch (cover crop rotation) Red clover (rotation crop) Alfalfa (rotation crop) Nitrogen-fixing legumes in rotation

Avoid planting near:

Continuous wheat monoculture (increases disease pressure) Other cereals in immediate succession without rotation Corn (shared pest pressures in some regions)

Common Pests

  • Delayed planting dates; resistant varieties like Garrison; crop rotation; destroy wheat residue

  • Tolerant variety selection; delayed planting; avoid planting near infected volunteer wheat

  • Scout for larvae; populations rarely justify treatment in wheat; predatory insects helpful

  • Crop rotation; destroy residue; early planting in fall

Uses

🍳

Flour & Bread Baking

Culinary

Garrison wheat produces hard red winter wheat flour suitable for bread, rolls, and baked goods with good protein content (12-14%) for strong gluten development. The flour has excellent baking properties and is preferred by artisan bread makers and commercial bakeries. [source]

🍳

Whole Grain & Grain Products

Culinary

Whole wheat berries can be sprouted, ground into flour, or processed into cracked wheat and bulgur. These products retain valuable fiber, B vitamins, and minerals. [source]

🏠

Straw Production

Household

Wheat straw is harvested along with grain and used for bedding, mulch, construction materials, and biofuel. Garrison's strong straw quality makes it suitable for these applications. [source]

🌿

Cover Crop & Soil Building

Agricultural

Winter wheat is an excellent cover crop for preventing erosion, suppressing weeds, and building soil organic matter when used in rotation. Garrison's vigor and winter hardiness make it particularly valuable in sustainable farming systems. [source]

🦋

Wildlife Habitat & Food

Wildlife

Wheat fields provide winter habitat and seed food for upland game birds, waterfowl, and songbirds, particularly when left standing or used in wildlife habitat programs. Grain remaining after harvest is an important food source. [source]

Harvest Tips

Harvest in mid to late July (zone 5) when grain moisture reaches 12-14%; combine when kernels are hard and cannot be dented with fingernail; monitor weather to avoid wet grain; cut at 3-4 inches above ground to leave residue for soil health; clean grain before storage; store at 12% moisture or below in cool, dry conditions

Fun Facts

  • 🌱 Garrison was developed by Kansas State University and is specifically bred for organic and sustainable farming systems, requiring no herbicides for weed control due to its exceptional allelopathic (weed-suppressing) properties.
  • 🌱 Winter wheat has an interesting survival mechanism called 'vernalization' — the plant requires exposure to prolonged cold (winter) before it can flower and produce grain, making fall planting essential.
  • 🌱 A single wheat plant can produce 50-100 tillers (shoots), meaning one kernel of seed can generate hundreds of kernels at harvest, making wheat one of the most efficient grain crops.
