Prefer a well drained rich loam soil or compost. Amaranth plants are susceptible to frost; if sow seeds outdoors, wait until soil has warmed and any chance of frost passed. It is safer to start indoors about 6 to 8 weeks before the last frost. Space seeds or seedlings 10 to 12 inches apart; cover seeds lightly with soil.
Water them during dry periods, once or twice per week. Add a general purpose fertilizer once or twice a season. Mulch plants to minimize weeds.
