When to plant
Direct sow after last frost when soil is warm. Germinates best at 65–75°F. Extremely heat-tolerant — one of the best summer greens when other crops bolt. Not frost-hardy; plant in full sun.
Soil & site
Adapts to poor, dry soils — excellent in challenging conditions. Prefers well-drained soil with pH 6.0–7.5. Work in compost at planting. Tolerates heat and drought much better than most vegetables.
Feeding
Light feeder. A moderate compost application at planting is enough. Excess nitrogen produces lush leaves but fewer grain seeds. Good choice for lower-fertility plots.
Common problems
Leaf miners create winding trails in leaves — remove affected leaves. Flea beetles make small holes in young leaves. Aphids on new growth. Very few serious pest problems — amaranth is generally tough and resilient.
When to harvest
Grain amaranth: seed heads are ready when they feel dry and papery and seeds release easily when rubbed. Leaf amaranth: harvest young leaves at any size — plants are ready about 4–6 weeks after planting. Heads are mature when the small flowers begin to dry and the majority of seeds are plump.
How to harvest
Leaf harvest: cut outer leaves or clip entire young plants an inch above the soil for regrowth. Grain harvest: cut the entire seed head and hang upside down in a paper bag for 2 weeks to finish drying. Thresh by rubbing heads between your hands over a tub, then winnow to separate seeds from chaff.
Storage & use
Fresh leaves: use like spinach, last 3–5 days refrigerated. Dried seeds: store in airtight jars for up to a year. Seeds can be popped like popcorn, ground into flour, or cooked as a grain. High in protein and iron.
