1. 🌱 Choose the Right Season

• Best time to sow: Early spring (Feb–Apr) or start of monsoon (June–July)

• Prefers warm temperate to tropical climates

• Ideal temperature for germination: 20°C to 30°C

2. 🌾 Seed Pre-treatment

• Seeds are small; no special scarification needed

• Soak seeds in clean water for 12 hours before sowing to enhance germination

3. 🪴 Prepare the Growing Medium

• Use a well-draining, sandy loam or potting mix

• Mix soil with compost and perlite (2:1:1) for aeration

• Soil pH: Slightly acidic to neutral (6.0–7.0)

4. 🌿 Sowing the Seeds

• Sow seeds thinly on the surface of the soil (do not bury deeply)

• Lightly cover with a thin layer (about ¼ inch or 0.6 cm) of soil or vermiculite

• Space seeds at least 1 inch apart in seed trays or pots

• Mist gently to avoid displacing seeds

5. 💧 Watering

• Keep soil consistently moist but not soggy

• Mist daily or water lightly as needed

• Good drainage is essential to prevent damping off

6. 🌞 Germination

• Germination time: 10–20 days

• Provide bright, indirect sunlight during germination

• Maintain warmth and humidity for better sprouting

7. 🌤️ Sunlight & Temperature

• Requires full sun once seedlings emerge

• Thrives in temperatures between 20°C and 35°C

• Can tolerate some drought once established

8. 🌱 Transplanting

• Transplant seedlings when 4–6 inches tall

• Use deep pots or plant directly in the ground with spacing of 2–3 meters (6–10 feet)

• Ideal planting during early monsoon or cooler parts of the day

9. 🌿 Fertilization

• Add organic compost or well-rotted manure at planting

• Apply balanced NPK fertilizer during active growth phases

• Supplement with micronutrients if needed

10. 🛡️ Pest & Disease Care

• Generally resistant to pests and diseases

• Watch for leaf-eating insects and treat with neem oil or organic insecticides if required

• Ensure good air circulation to reduce fungal risks

11. 🌳 Growth & Maintenance

• Fast-growing tree, reaching up to 30 meters in ideal conditions
