How to Grow

1. The seeds have a hard coat — soak them in warm water for 24 hours before sowing, or germination will be poor.
2. Fill a seedling tray or small container with a fine, clean, well-draining seed-starting mix.
3. Sow the seeds: 1–2 cm deep. Soak the seeds in warm water for 24 hours before sowing.
4. Water gently with a spray bottle and keep the medium moist, not waterlogged.
5. Under suitable conditions, sprouts usually appear in 10–25 days after hot-water treatment.
6. Transplant to the final pot or bed once the seedlings are sturdy, and grow on in full sun.

Light, water, soil and feeding

• Light: Full sun
• Water: Regular watering for the first 1–2 years; drought tolerant after that.
• Soil: Well-drained soil; it tolerates a wide range, including poor soils.
• Temperature: 20–42°C; very well suited to the Indian plains.
• Fertiliser: Compost or farmyard manure once a year at the onset of the monsoon.
• Pruning: Shape the young tree; it also tolerates coppicing.

Sowing season in India

February–March, or June–July with the monsoon. Exact timing depends on your local temperature and conditions.

Common problems

• Poor germination: The hard seed coat needs a 24-hour warm-water soak before sowing.
• Waterlogging damage: Plant in well-drained soil and avoid standing water.
