Growing Instructions from Seeds

Amaranthus seeds are very small.

Surface sow or cover the seeds only very lightly with fine growing medium.

Do not sow deeply.

Keep the growing medium:

Once seedlings become established, thin or carefully transplant them into their final pots, grow bags or garden beds.

Germination

Seeds generally germinate within:

7–14 days

under suitable warm conditions.

For successful germination:

• Use fresh seeds

• Maintain warm temperatures

• Keep the growing medium lightly moist

• Avoid deep sowing

• Maintain good drainage

Plant Spacing

Maintain approximately:

30–45 cm / 12–18 inches between plants

to encourage healthy growth, good airflow and attractive foliage development.

Sunlight

Provide:

Full sun to partial sun

For stronger growth and better foliage colour:

5–6+ hours of direct sunlight daily

is recommended where possible.

In extremely hot summer conditions, some protection from intense late-afternoon sunlight can be beneficial.

Watering

Water regularly while young plants are becoming established.

After establishment:

Water when the upper soil layer begins to dry.

Keep the growing medium moderately moist but well-drained.

Avoid continuous waterlogging.

Feeding

At planting time, mix:

GREEN GARDENS Vermicompost

Amaranthus performs well in moderately fertile soil enriched with organic matter.

Avoid excessive fertilizer application, particularly excessive nitrogen.
