Planting Instructions
- Soil Preparation: Choose loose, humus-rich, well-drained loam soil. Avoid compacted clay soil and waterlogged conditions to prevent root rot.
- Sowing Method: Scatter tiny seeds evenly over the soil surface, cover with a thin 0.3cm soil layer, and gently press the soil for better seed contact.
- Germination Condition: Keep soil slightly moist but not soggy. Maintain a stable temperature of 15–22°C. Seeds germinate in 7–14 days.
- Seedling Care: Thin overcrowded seedlings to ensure airflow and growing space. Full sunlight promotes sturdy stem growth and prevents spindly plants.
- Daily Maintenance: Water moderately at soil drying. Avoid overhead watering to reduce fungal risk. Deadhead faded flowers regularly to encourage continuous new blooms.
