About Amaranth (Chaulai / Rajgira)

Amaranth (chaulai saag) is a fast-growing leafy vegetable and grain crop used across Indian, African, and Central American cuisines. The leaves are cooked like spinach; the seeds (rajgira) are a nutritious grain used in laddoos and rotis. Extremely productive and heat-tolerant.

Direct sow after last frost — grows rapidly in heat. Harvest outer leaves continuously for greens. For grain, let seed heads mature and turn brown, then thresh over a bucket. Leaf amaranth is ready in 6-8 weeks. Self-seeds prolifically — deadhead if you do not want volunteers.
