Sow indoors in winter for an early start or in spring once the soil has warmed.

Amaranth seeds are very small, sprinkle over a prepared area and cover with a light layer of soil, or just water them in allowing them to sink naturally into the soil.

Transplant in mid spring once the risk of frost has passed.

If transplanting, plant out in the early morning or evening and/or on an overcast day. Avoid planting at peak sun times and on windy days, this will allow your plants to settle in comfortably and protect them from windburn and sunburn. 

Once seedlings are a reasonable size, mulch the soil around them well to retain moisture. 

Before planting, prepare the soil by working in compost. Feed with a very light application of organic fertilizer throughout the season if leaves show signs of deficiency.
