Fall Green Manure Mix - Key Growing Information

Green manures are specific plants, crop varieties, or mixes that are grown and turned into the soil to improve overall quality, particularly fertility and tilth.
Uses: A quick, dense cover crop blend for mid- to late-summer sowing, made up of winter rye, field peas, ryegrass, crimson clover and hairy vetch. It gets established fast in cool, wet fall weather and forms a thick mat that protects soil from erosion.
Culture: Sow anytime from midsummer to late summer. It does best in full sun with moderate to high fertility and good drainage, but grows in nearly any soil; ideal pH is 6.0–7.0. Plant ½" deep, or broadcast and cover lightly. For larger areas, broadcast or use a grain drill at the rates below.
Seeding Rate: ¼ lb. per 225 sq. ft.; 1½ lb. per 1,000 sq. ft.; 50 lb. per acre.
Height: 24–36"
Termination: The field peas winterkill, while winter rye and hairy vetch survive to regrow in spring. Crimson clover and ryegrass usually winterkill in Zone 6 and colder, depending on sowing date, snow cover and winter weather. To use the mix as green manure, mow and till it in during spring. Once the rye and vetch have flowered, they can be crimped or mowed and left as a surface mulch.
