Jet Black Barley - Organic Cover Crop Seeds

Sow barley in early spring as soon as the soil can be worked, or in fall where winters are mild enough for the chosen variety to survive. Spring barley matures during the warmer months, while winter barley is planted in autumn, rests through cold weather, and resumes growth in spring.

For cover cropping, sow after a garden bed is cleared or several weeks before the soil is expected to freeze. Barley establishes quickly in cool weather but is less winter-hardy than cereal rye, so it may winterkill in colder climates and leave an easy-to-manage mulch behind.

Barley is direct sown rather than transplanted. Prepare a firm, weed-free seedbed and sow seed about 1–1½ inches deep.

For grain, broadcast seed evenly and rake it in, or plant in rows about 6–8 inches apart. Aim for a dense, even stand that fills the bed without becoming so crowded that airflow is restricted.

For a cover crop, broadcast more densely so the plants close over the soil quickly. Rake the seed into good contact with the ground and water gently if rainfall is not expected.

Choose a site in full sun with loose, well-drained soil. Barley grows well in moderately fertile ground and usually does not need heavily enriched soil.

Keep grain plantings free of weeds during early growth. Once the plants begin producing side shoots and filling in the bed, they compete more effectively with weeds and shade much of the soil surface.

Water during extended dry periods, especially while grain heads are forming and kernels are filling. Cover-crop stands usually need little care after establishment unless conditions remain unusually dry.

When barley is grown to improve the soil rather than for grain, cut it before the seed heads fully mature. The tender growth can be left on the surface as mulch or chopped and worked shallowly into the soil. Allow time for the plant material to begin breaking down before planting the next crop.

For grain, harvest when the plants and seed heads have turned golden and the kernels are hard enough that they cannot be easily dented with a fingernail. The stems should be dry, but the heads should still hold together without heavy shattering.

Cut the stalks near the base and gather them into loose bundles. Allow them to finish drying in a warm, protected, well-ventilated place.

Thresh the dry heads by rubbing or beating them over a clean surface. Winnow the grain in a light breeze or in front of a fan to separate the kernels from the chaff. Dry the cleaned grain thoroughly before storage.

For cover-crop use, cut barley while it is still green and before mature seed forms. Earlier cutting produces softer material that breaks down more quickly, while later growth creates more biomass but takes longer to decompose.

Whole barley provides fiber, protein, manganese, selenium, phosphorus, magnesium, and B vitamins. It is especially known for beta-glucan, a soluble fiber found in the grain.

Use hulled barley in soups, stews, grain bowls, pilafs, and porridge. Pearled barley cooks more quickly but has part of the outer grain layer removed. Barley can also be malted, ground into flour, sprouted, or used as feed for poultry and livestock.

As a cover crop, barley helps keep soil covered between plantings, slows erosion, captures nutrients that might otherwise be lost, competes with weeds, and contributes carbon-rich plant material to the bed.

Birds may pull newly sown seed or feed on ripening grain heads. Netting, light row cover, or temporary deterrents can help protect small plantings.

Aphids, armyworms, grasshoppers, and cereal leaf beetles may feed on foliage or heads. Inspect the crop regularly and maintain flowering habitat nearby for beneficial insects.

Rusts, smuts, leaf spots, and root diseases are more likely where grain crops are crowded, repeatedly grown in the same ground, or planted in poorly drained soil. Rotate barley with broadleaf crops and remove heavily diseased residue after harvest.

Barley is primarily self-pollinating, so different varieties usually cross at low rates. Even so, grow only one variety or provide some separation if maintaining seed purity is important.

Save seed from healthy, vigorous plants with uniform height, maturity, head shape, and grain quality. Allow the heads to dry fully before harvest, but gather them before the kernels begin to shatter.

Thresh and winnow the grain, then remove shriveled, discolored, or damaged kernels. Dry the seed thoroughly and store it in a labeled, airtight container in a cool, dark place.

• Sow into a clean, firm seedbed.
• Use a denser planting for cover-crop purposes.
• Cut cover-crop barley before mature seed forms.
• Harvest grain before the heads begin to shatter.
• Dry grain completely before storage.
