Spring Wheat (Glenn) Organic Cover Crop Seed
Excellent milling and baking quality.
Very good test weight and protein. Glenn hard red spring wheat has excellent all-around disease resistance, with the best tolerance to scab (Fusarium head blight) we have found. Sow as early as possible in spring (delay reduces yield), about 4 lb./1,000 sq.ft. (120–140 lb./acre), less in drier climates. Harvest August–September. Plant Variety Protected. Blue label/Certified seed. USDA Certified Organic.Specs:

Culture: Spring grains can be sown ¾–1.5" deep using a push seeder or grain drill. They can be broadcast at slightly higher rates, then lightly harrowed or pressed in with a cultipacker. Spring grains tend to prefer cooler spring or fall conditions but can be summer sown in cooler regions with success. For a fall cover crop, plant by early September in northern regions or slightly later in the South. Spring grains do not require vernalization to produce seed, but if growing for an edible grain harvest, seeds must be sown early in the spring to ensure enough time for the grain to mature. Sow approximately four weeks before the last frost date for a late summer harvest.
Seeding Rate: Sow at the lower end of the stated rate when drilling or sowing as a nurse crop for a legume. For a thick, winterkilled cover crop, in challenging growing conditions, or when broadcasting, sow at the higher end of the stated rate. Barley: 2 lb./1,000 sq.ft.; 60–125 lb./acre. Oats: 4 lb./1,000 sq.ft.; 100–140 lb./acre. Spring Wheat: 2–3 lb./1,000 sq.ft.; 60–150 lb./acre. Use lighter rates for grain harvest in dry climates.
Light Requirements: Full sun
Soil Requirements: Barley: Barley prefers light, moderately fertile soils with a pH of 6.0–8.5. Tolerates saline and alkaline soil but does poorly in wet or acidic conditions. Oats: Dry, well-drained, poor-to-average soil. Drought tolerant. Ideal pH is 5.0–6.5. Spring Wheat: Dry, well-drained, average soil. Drought tolerant but will not do well in clay soil.
Height: See individual product description.
Harvest: For grain harvest, wait until the plant has turned brown and begun to dry down. The seeds should no longer be milky and have begun to harden (hard dough stage). Combine or cut and stack in bundles to promote further drying. When fully dried, thresh and winnow the grain for storage. For ornamental use, cut grains when the seed head has matured, but is still green and fresh looking.
Termination: Spring grains can be terminated using tillage at any stage before the flower heads emerge. Multiple passes or more aggressive tillage may be required as the crop matures. After flower emergence, termination becomes more difficult to manage with tillage. After flowers begin to shed pollen, mowing or crimping grains will create a dense mat of mulch on the soil's surface. Multiple passes may be required to get any plants that rebound. Applying tarps after mowing or crimping will help ensure termination and speed up decomposition.
