Grain Sorghum, also known as Milo (Sorghum bicolor), is a vigorous warm-season annual used to produce biomass, protect bare soil, and add diversity to seasonal cover crop programs. Its upright growth and extensive root system make it a practical choice for gardens, orchards, vineyards, and larger agricultural plantings. During the hottest part of the growing season, Grain Sorghum helps keep living roots in the soil while producing substantial plant material that can later be mowed or incorporated to contribute organic matter.Best planted in late spring or early summer after the danger of frost has passed and soil temperatures have warmed, Grain Sorghum performs best in full sun and well-drained soil. It is well suited to warm conditions and can be planted alone or combined with compatible species in a mixed cover crop planting. Its dense, upright growth can help shade the soil surface and make productive use of open ground between cash crops or during periods when beds and fields would otherwise remain unused.Use Grain Sorghum as part of a warm-season soil management plan to generate biomass, maintain active plant growth, and support long-term soil-building goals. Whether planted in a garden bed, orchard alley, vineyard row, or open field, it offers growers a dependable option for keeping the soil covered and returning plant material to the ground.For other seasonal cover crops and green manure options, explore our full collection of cover crop seeds.Grain Sorghum / Milo – Warm Season Biomass Cover CropDid You Know?
