Reaches 15-20 m (49-66 ft) with a dense rounded crown up to 20-25 m wide. Compound pinnate leaves with 20-30 serrated leaflets. White fragrant flowers in drooping panicles (250-300 flowers). Olive-like drupes ripen green to yellow, containing 1-3 seeds (kernels) source of neem oil (azadirachtin). Sacred tree in Hinduism; used in Ayurvedic medicine for centuries. Natural insecticide, fungicide, fertilizer (neem cake). Termite-resistant timber (mahogany family). Excellent shade tree for hot, drought-prone areas. Can live 200+ years. Invasive in parts of Africa and Australia.

### Seasonal Care & Maintenance Guide for Neem Tree - **Light Requirements**: Requires bright indirect sunlight; protect from harsh direct mid-day rays. Ensure ample light to maintain tight growth nodes and vibrant coloration. - **Watering Routine**: Moderate – Water when the top 1–2 inches of soil feel dry to touch. Always test soil moisture before watering. Ensure drainage holes are completely unobstructed to prevent root rot. - **Temperature & Humidity**: Thrives at 18°C–35°C (65°F–95°F). Protect from frost, cold drafts, and prolonged water stagnation during monsoon months. - **Pruning & Training**: Prune dead, leggy, or yellowing stems during early spring to stimulate fresh bushier growth and abundant blooms.

### Potting & Planting Instructions for Neem Tree 1. **Container Selection**: Choose a terracotta, ceramic, or nursery pot with generous drainage holes at the base. 2. **Soil Mix Recipe**: Use Aerated, rich potting mix with coco peat, perlite, and vermicompost (pH 6.2–6.8). Adding a layer of coarse gravel or leca at the bottom enhances oxygenation. 3. **Planting Depth**: Position the plant at the exact same root collar depth as in its nursery container. Avoid burying stems too deep. 4. **Initial Settling**: After potting, water thoroughly until water drains freely, then place in bright indirect light for 3–5 days to acclimatize before moving to full sun.

Harvest mature stems/leaves as needed using clean sterilized pruning shears.

Pairs wonderfully with drought-tolerant companion plants and complementary shade trees varieties.
