01Grain and leafy green in one plant

Amaranth is unusual in offering two harvests from one planting — pick young leaves as a nutritious green through the season, then let some plants mature fully for a grain harvest.

02Planting

Method

Direct sow, surface sown, needs light to germinate.

Soil

Tolerant of poor soil; free-draining preferred.

Timing

Sow after frost risk passes.

Planting timing varies significantly by Australian climate zone. Set your zone above (or use the Find My Climate Zone tool) for guidance tailored to your own area.

03Growing care

Thin as seedlings establish if grown densely for leaf.
Water while establishing, then rely mostly on rainfall — quite drought-tolerant.
Harvest leaves regularly from a portion of the crop.
Let remaining plants mature fully for a grain harvest.

04Problems

Very few pests — a hardy, easy crop.
Bird competition for grain — net maturing seed heads if harvesting for yourself.
Self-seeding beyond bounds — harvest before full seed drop if containment matters.
Waterlogging — ensure reasonable drainage.

05Harvest & storage

Signs

For grain: seed heads dry and seeds fall easily when rubbed. For leaf: pick young, tender leaves anytime.

Method

For grain: bend heads over a container and rub to release seed.

Curing

Dry seed thoroughly before storing.

Storage

Grain: airtight, cool, dark, many months. Leaves: fridge a few days.

Preserving

See Dehydrating (drying grains fully for storage) for ways to keep a harvest surplus.

Rotation note

Rotate loosely; not a heavy feeder.

Amaranth is an easy grain & staple to grow, needing full sun with low–moderate, drought-tolerant watering.
