Austrian Winter Peas are a winter cover crop in zones 6 and up. Hardy to 0°F. A great edible cover crop - snip off the tendrils and growing tips for salads! Flowers earlier (April) than hairy vetch.  For maximum nitrogen fixing, wait until at least 50% of the plants have flowered before mowing crop.  Ready to harvest in 60 days.

Sow Buckwheat any time between last spring frost and 1 month prior to first fall frost. A great quick summer crop, fast growing plants choke out weeds. Bees love the white flowers that appear in 4 to 5 weeks.

The tender stems are easy to cut down when the crop's done. For a fall/winter cover crop we recommend sowing buckwheat together with crimson clover. The buckwheat acts as a nurse crop for the crimson clover during the heat of the day. In the fall, the buckwheat is killed by frost. Organically grown.  Ready to harvest in 30-45 days.

Crimson clover fixes up to 200 pounds of nitrogen per acre, and prefers well-drained, loam soils with good organic matter content for best results. It is an excellent choice for under-seeding as it grows well in the shade of other crops. Easier to incorporate in the spring than Hairy Vetch.

Do not use for frost seeding as it won't handle the cold. Crimson clover will not re-grow after close grazing or mowing once flowering has begun. Crimson clover does best in cool, humid weather and will perform poorly in the heat of summer.  Blooms in 70-90 days.

Versatile choice for late summer and fall planting. This ready-made mix is comprised of winter rye, field peas, ryegrass, crimson clover, and hairy vetch. Vigorous late summer growth provides winter erosion control. The peas, clover, and ryegrass will winter kill to provide organic matter and soil cover. The hairy vetch and winter rye will regrow in the spring to provide nutrients for crops to utilize. Because the seeds of this mix vary in weight and size, it is best seeded with a grain drill.

Use Hairy Vetch cover crop seeds for short-term, legume green manure for nitrogen fixation. Sow spring to late summer with or without grain, grass, or field peas. When sown late summer, spring regrowth is vigorous and nitrogen producing for tilling in before planting the spring garden crops.   May have some allopathic properties, so it is best to allow 2-3 weeks between incorporating and seeding of small-seeded crops. This selected hardy strain is widely adapted and withstands all but severe winters if sown in late summer or fall.  Blooms in 60-300 days.

Large plant with big leaves makes it an ideal grazing crop. In addition to its uses for nitrogen fixation and as forage, the flowers of red clover may be used to garnish drinks, salads, soups, and desserts; the flavor is sweet and mild.   Mammoth Red Clover may be the best choice for frost seeding; it is extremely cold hardy and does well in most soils and growing conditions. it does, like most clovers, perform poorly in hot weather unless seeded into a crop canopy. Incorporate fully for best results.  Blooms in 70-90 days.

Annual rye grass is a very competitive winter annual, with good seedling vigor, fast germination (with adequate moisture) and rapid establishment. Annual rye grass is a bunch grass, yellowish-green at the base, with long glossy green leaves up to 12 inches each. it will overwinter in certain years.

Annual rye grass grows vigorously under a wide range of soils and climates. It is tolerant of wet soils and temporary flooding, and will grow in sandy soils, but is better adapted to heavy clay or silty soils. Annual rye grass tolerates a pH range of 5-8 with the optimum between 6 and 7. Can become a weed if allowed to set seed.   Ready to harvest 1st August-15th November.

Sweet Clover is a tremendous green manure and honey plant. Sweet clover can grow nearly anywhere, with as little as 16 inches of rainfall per year. It has deep tap roots that mine soil nutrients and water from deep within the soil. It is better than many of the other clovers for nutrient recycling and appears to have a greater capacity to extract potassium, phosphorus and other soil nutrients from insoluble minerals.

Sow in spring to summer at 1/2 lb./1,000 sq.ft. (15 lb./acre) as an annual, or let grow the next year over 6 ft. tall. Should be grown with 1½ to 2 bushels of oats as a "nurse" crop. Sweet clover is slow to establish the first year and may have some winter kill without adequate snow cover.

Second year growth is tremendous. Will fix as much nitrogen as alfalfa and doesn't require an acid soil. Can produce as much as 170 lb. of nitrogen per acre although 100 lb. per acre is closer to the average. Excellent conditioner for poor and thin soils. Mostly yellow with some white flowers. Organically grown.  Ready to harvest in 70-90 days.

Winter Rye cover crop is great for controlling erosion, adding organic matter, enhancing soil life, and suppressing weeds. Its extensive root system makes it among the best green manures for improving soil structure. It is an excellent soil renovator and pioneer crop for new fields.

Rye is very good at releasing phosphorus and potassium. It also stabilizes excess soil and manure nitrogen. Rye and vetch together are one of the preferred cover crops for no-till tomato planting. Rye is also good for animal grazing; it's highly palatable and of high nutritional quality, and comes back from grazing and grows again. Rapid establishment and growth together with weed suppression make rye an excellent choice for certified organic growers. Sow Aug. 1 first Nov. 15 as a winter cover crop. Organically grown.  Sow August 1st thru November 15th as a winter cover crop.
