February to March: Sow seeds in a well-drained seed mix. Lightly cover with fine sand or vermiculite to retain moisture and ensure good seed-to-soil contact. | |
April to May: Germination usually occurs in 2-4 weeks. Maintain a temperature of 18-24°C (65-75°F) and keep the environment humid with a humidity dome or plastic cover. | |
May to June: Transplant seedlings after the last frost. Gradually acclimate them to outdoor conditions over a week to harden off before planting. | |
July to September: Flowers bloom from mid-summer to early autumn, showcasing vibrant red petals with yellow stamens. | |
90-120 cm: Space plants 3-4 feet (90-120 cm) apart to allow for their full growth and to ensure proper air circulation. | |
1.25 cm: Sow seeds 1/2 inch (1.25 cm) deep. For transplants, ensure the root ball is covered with soil but avoid planting too deeply. | |
Well-drained, fertile soil: Prefer a rich soil mix with compost or well-rotted organic matter. Avoid heavy clay soils that retain excess water. | |
Moderate: Water consistently to keep the soil moist but not waterlogged. Adjust watering during dry spells to prevent stress. | |
