The threeawn genus includes plants often adaptable to various climatic conditions. For optimum growth, plant in well-draining, sandy or rocky soil under full sun exposure. As threeawn tolerates drought, water moderately to avoid overwatering. Begin with loosening the soil in the planting area, laying out the plants, and covering the roots with soil. Regularly check on plants to monitor their health. Despite commonalities, individual species may have unique needs, and understanding these differences can aid successful planting.
