Seed Treatment
- Soaking: Soak seeds in warm water for 4–6 hours before sowing to soften the seed coat and encourage quicker sprouting.
Sowing Instructions
- When to Sow:
- Indoors: Start seeds 4–6 weeks before the last frost date.
- Outdoors: Direct sow in late spring, once the danger of frost has passed and soil is warm.
- Soil Requirements:
- Prefers well-draining, moderately fertile soil.
- Ideal pH: 6.0–7.5 (slightly acidic to neutral).
- Avoid overly rich soils, which may reduce leaf coloration.
- Light Requirements:
- Requires full sun (6+ hours daily) for best color development and healthy growth.
- Sowing Depth:
- Sow seeds ¼ inch (6 mm) deep.
- Cover lightly with soil and gently firm.
- Watering:
- Keep soil evenly moist during germination.
- Once established, Amaranthus tricolor is drought-tolerant, but regular watering will encourage lush foliage.
- Germination Time:
- Germinates in 7–14 days at an ideal temperature of 70–75°F (21–24°C).
- Spacing:
- Thin or transplant seedlings 10–18 inches (25–45 cm) apart, depending on the variety and desired fullness.
Growing Tips
- Grown primarily for its striking, tricolor foliage in shades of red, yellow, and green.
- Great for ornamental beds, edible landscaping, or tropical-style gardens.
- Can be harvested for young edible leaves, which are nutritious and flavorful.
- Pinch back young plants to encourage bushier growth.
- May self-seed in the garden if left to flower.
