Alfalfa is an extremely adaptable perennial legume that fixes atmospheric nitrogen and improves soil health wherever it grows. Plant in full sun with well-drained soil and water deeply but infrequently once established to encourage its deep taproot system. It is highly drought tolerant once mature and requires minimal fertilization due to its nitrogen-fixing ability.
