Strategic use of cover crop seed is an investment in the land that pays dividends in the form of greater long-term productivity and sustainability. With rich potential for a diversity of applications, farm seed and cover crops control erosion, add organic matter, conserve moisture, and support the integrity of soil and watershed ecology. By growing your own inputs, you economize on fertilizers, animal feed, and hay mulch, while improving the overall health of your livestock, soils, crops, the food you produce and, ultimately, the surrounding environment.
Available in one ounce and 14 ounce sizes.

Buckwheat Cover Crop Organic One Ounce Package
Buckwheat Cover Crop Organic 14 Ounce Package
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. Mature in 30 to 45 days as a green manure crop and 80 days for a grain.
Crimson Clover Cover Crop Organic One Ounce Package
Crimson Clover Cover Crop Organic 14 Ounce Package
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. Harvest in about 90 days.
Clover Mammoth Red Organic Cover Crop One Ounce Package
Clover Mammoth Red Organic Cover Crop 14 Ounce Package
The best clover for poor soils. Tall (2 to 3 feet), quick-growing clover. Sow in spring, summer or fall. Will grow in more acid soil (pH 5.0 to 6.0) than other clovers if lime is applied at seeding time. Widely grown biennial used for Nitrogen addition and hay crops. 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.
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. Mammoth Red clover will fix up to 70 to 110 pounds of nitrogen per acre. The long tap roots loosen soils and mine phosphorus and other nutrients from deep in the soil. It should be seeded with 1 and 1/2 to 2 bushels/acre of oats to "nurse" the clover. Organically grown. Blooms in about 70 to 90 days.
Clover Medium Red Cover Crop Organic One Ounce Package
Clover Medium Red Cover Crop Organic 14 Ounce Package
Low-growing, multi-cut clover. Fast to establish, tolerates most soil types, and is suitable for hay or silage. Often used as a cover crop between rows of vegetable crops if mowed to maintain manageability. NOTE: Seed is coated with APEX Green Hydroloc, an OMRI-listed seed coating that contains a mix of minerals, nutrients, and rhizobia bacteria for enhanced germination and plant growth. Organically grown. Harvest in about 90 days.
Clover New Zealand Cover Crop Open Pollinated One Ounce Package
Clover New Zealand Cover Crop Open Pollinated 14 Ounce Package
An improved pasture white clover. Previously sold under the name White Dutch Clover. Once established, white clover can handle foot and tractor traffic better than other clovers. The fibrous root system typically is in the top 8 inches of soil, although it does have up to a 40 inch tap root in the first year which dies each fall, leaving a passage for water to percolate through.
More heat tolerant than some of the larger clovers, it is a low-growing (to 12 inches) perennial that can be sown into long-season row crops during the season to provide a "living mulch." Sow after first cultivation at 1/4 pound per 1,000 square feet and rake or cultivate to cover. Also used for green manure, hay, and pasture. Harvest in about 70 days.
Clover Sweet Cover Crop Organic One Ounce Package
Clover Sweet Cover Crop Organic 14 Ounce Package
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. Harvest in about 90 days.
Fall Green Manure Cover Crop Open Pollinated One Ounce Package
Fall Green Manure Cover Crop Open Pollinated 14 Ounce Package
Versatile choice for late summer and fall planting. This ready-made mix is comprised of winter rye, field peas, rye grass, crimson clover, and hairy vetch. Vigorous late summer growth provides winter erosion control. The peas, clover, and rye grass 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. Days to bloom vary.
Hairy Vetch Organic Cover Crop One Ounce Package
Hairy Vetch Organic Cover Crop 14 Ounce Package
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. Harvest in about 60 days.
Iron and Clay Cover Crop Open Pollinated One Ounce Package
Iron and Clay Cover Crop Open Pollinated 14 Ounce Package
Iron and clay cowpeas can be used in one of three ways. They can be eaten, nitrogen fixation or as fodder for animals. Southern favorite. Bushy 2 to 3 feet plants bear prolifically. 6 to 9 inch pods with large, creamy-white seeds, 18 to 20 seeds per pod, easy to shell. Unusually, seeds have a taste between English peas and cowpeas when fresh.
A great cover crop for warm weather and Southern growers. Grown much like soybeans. Frost sensitive, but fast growing to 2 and 1/2 feet in warm/hot weather. Sow mid-spring once soil has warmed. Drill at 25 to 50 pound per acre or broadcast up to 120 pound per acre, 1/2 to 1 inch deep. Relatively long taproots help withstand drought. Cowpeas are not tolerant of high weed pressure or wet soils and will perform poorly in these conditions.
If planted thickly, they will smother out weeds. Cowpeas can also be used for under-seeding in spring crops and tilled under prior to fall-planted crops. They can produce as much as 315 pound per acre nitrogen, although 130 pound per acre is more typical. High organic matter production. They can also be used as fodder for animals. Harvest in about 80 days.
Mighty Mustard Pacific Gold Cover Crop One Ounce Package
Mighty Mustard Pacific Gold Cover Crop 14 Ounce Package
Fast growing control for nematodes and soil fungi. Produces 4 to 5 tons of organic matter per acre. Mow before plants set seed and incorporate into the soil immediately to have the best effect on these soil pests. With proper management, this crop may be used as an organic replacement for methyl bromide. Sow at 15 to 20 pounds per acre. Blue label/Certified seed. Harvest in mid- to late summer.
Spring Green Manure Cover Crop Organic One Ounce Package
Spring Green Manure Cover Crop Organic 14 Ounce Package
Enrich the soil with both nitrogen and organic matter. The mix contains field peas, oats, and hairy vetch. Designed for spring sowing, but it may be sown anytime early spring through late summer.

Annual ryegrass 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 ryegrass 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 to 8 with the
optimum between 6 and 7. Can become a weed if allowed to set seed.
Sow August 1st thru November 15th as a winter cover crop.
