Planting and Growing Amaranthus

Grow in a warm sunny position, in a rich, moist but well drained soil. Tolerant of poor soils.

Ideal for sunny beds or borders. Often grown as a centrepiece in a formal bedding.

Popular with flower arrangers. The flowers are long-lasting and can be dried for winter decoration.

Taking Care of Amaranthus

Keep weeded and water freely during dry weather.

To improve flowering, apply an all-purpose flowering plant food (slightly higher in phosphorus and potassium) every few weeks, or use a slow release form. Do not over fertilize.


Deadhead regularly to extend the flowering period. Pull up and discard plants in autumn.

Birds love the seed heads, so leave a few spent flowers for them to enjoy.

Pests and Diseases

Susceptible to attack by Aphids. Generally disease free.

Propagating Amaranthus

Sow seed under glass in early spring and keep at a temperature of 15°C (59°F). Prick out, pot on, and harden off before planting out in late spring.

The seed can also be direct-sown in late spring. Sow in a prepared seed bed where the plants are to flower. Thin out as necessary.
