Organic Red Clover - Raw Seed (lb)

Organic Red Clover is a reliable cool-season legume cover crop that improves soil fertility, supports pollinators, and enhances overall soil health for gardeners and small-scale farmers. Also called Mammoth Red Clover, this short-lived perennial produces lush foliage and globe-shaped pink flowers that attract bees and other beneficial insects. Its deep root system breaks up compacted soil, improves aeration, and increases water infiltration, making it an excellent choice for sustainable gardening and regenerative farming practices.

Best planted in spring or fall, Organic Red Clover thrives in well-drained, high-calcium soils and tolerates cold weather once established. It fixes atmospheric nitrogen through its symbiotic relationship with rhizobia bacteria, adding this essential nutrient back into the soil naturally. Use it as green manure, erosion control, or forage for livestock. The dense growth habit suppresses weeds, while mowed clover can regrow for continued soil benefits. For optimal results, inoculate seeds with a clover-specific inoculant before planting.

This versatile cover crop adapts to a wide range of soil pH levels and performs well in full sun to partial shade. It’s ideal for resting garden beds, preparing new planting areas, or building long-term soil vitality between growing seasons. Incorporate it at bloom stage to add organic matter and nutrients for the next crop cycle.
