Its leaves, stems, and seeds are all edible, commonly used in salads, soups, and grain-based dishes.
When and Where to Sow British Red Amaranthus Seeds
- Indoor Sowing: Start seeds indoors from early spring (March to April) to give plants a head start. Sow in pots, containers, or seed trays and place in a greenhouse or on a sunny windowsill.
- Outdoor Sowing: Direct sow outdoors from late spring to early summer (May to June) once the risk of frost has passed. Choose a warm, sunny, and well-drained location for best growth.
Ideal Growing Conditions for British Red Amaranthus
- Soil Requirements: Prefers light, well-drained, fertile soil enriched with organic matter. Ensure soil is loosened and free from weeds before planting.
- Sunlight: Requires full sun for optimal growth and vibrant colour.
- Temperature: Ideal germination temperature: 18-24°C (64-75°F). Young seedlings need protection from cold temperatures and late frosts.
How to Sow British Red Amaranthus Seeds Indoors
- Prepare Containers: Fill seed trays or small pots with fine, well-draining seed compost.
- Sowing Depth: Sow seeds 2 mm deep, pressing them gently into the soil without burying them too deeply.
- Watering: Keep the compost evenly moist but not waterlogged. Cover trays with a clear plastic wrap or glass to retain humidity until seedlings emerge.
- Germination Conditions: Place in a warm, bright location (18-24°C). Germination occurs within 7-14 days under ideal conditions.
- Thinning Seedlings: Once seedlings appear, remove the weakest ones to allow stronger plants to thrive.
How to Sow British Red Amaranthus Seeds Outdoors
- Soil Preparation: Work the soil to a fine tilth and mix in compost or well-rotted manure for added nutrients.
- Sowing Depth: Scatter seeds on the surface and cover lightly with fine soil.
- Spacing: If growing in rows, space plants 30-45 cm (12-18 inches) apart.
- Watering: Water gently after sowing and keep the soil moist but not soggy.
Caring for British Red Amaranthus Plants
- Watering: Water regularly, particularly in hot weather, but avoid overwatering as amaranthus is drought-tolerant once established.
- Fertilising: Apply a general-purpose fertiliser once during early growth for stronger stems and healthier foliage.
- Weeding and Mulching: Keep the area weed-free and apply a thin layer of mulch to retain soil moisture and suppress weeds.
- Supporting Tall Plants: If grown in exposed areas, stake tall plants to prevent them from toppling in strong winds.
Harvesting British Red Amaranthus
- When to Harvest: Leaves can be harvested from 30 days after sowing for fresh greens. Tassels and seeds mature after 90-120 days.
- How to Harvest: For leaves, pick young, tender leaves for the best flavour. For seeds, allow tassels to dry on the plant, then shake to release seeds.
