Within ten days of blooming (or at any time before), Crimson clover produces ample organic matter that can be used as a mulch on the surface, or cut and tilled under to improve soil tilth and promote soil health. Continue reading below for tips on how to grow crimson clover from seed.
Exposure: Full sun to partial shade
Plant any time between the last frost date and early autumn. Hardy to Zone 6: -23°C (-10°F).
Sow seeds no deeper than 5mm (¼").
Crimson clover can be worked into the soil easily with a garden fork. For nitrogen fixation, allow the plants to grow until flowering begins, and simply remove the tops and compost, leaving the roots intact in the soil. Allow ten days before planting the next crop, and avoid following with legumes like peas, beans, or soy.
