2. Origin and Natural Habitat
The Neem tree is native to India, Nepal, Bangladesh, Pakistan, and Sri Lanka, but has been introduced to many tropical and subtropical regions worldwide due to its resilience and usefulness. It thrives in hot, arid, and semi-arid climates, tolerating poor soils, extreme heat, and minimal rainfall.
3. The Neem Tree Life Cycle – From Seed Dropping to Growth
A. Flowering and Seed Formation
- Neem trees start flowering after 3–5 years of planting.
- The flowers are small, white, and fragrant, attracting bees and other pollinators.
- Pollination results in the formation of small olive-shaped fruits.
B. Seed Dropping
- Fruits mature in 3–4 months after flowering.
- Ripe fruits turn yellowish-green and fall to the ground naturally.
- Animals such as birds, squirrels, and bats often feed on the fruits, aiding in natural seed dispersal.
C. Germination Process
- Fresh neem seeds have a high germination rate, but they must be sown within 2–3 weeks after harvesting because they lose viability quickly.
- Germination occurs 7–14 days after sowing.
- Seeds should be planted about 2–3 cm deep in moist soil.
- Direct sunlight is essential for healthy sprouting.
D. Sapling Growth
- The first year’s growth is relatively slow as the plant develops a strong root system.
- Neem has a deep taproot, which helps it survive droughts.
- By the second year, it grows faster, reaching 2–3 meters in height.
E. Maturity
- A Neem tree is considered mature after 10–15 years.
- Fully grown trees can yield up to 50 kg of fruit annually.
4. Physical Features of Neem Tree
- Leaves: Dark green, pinnate, with 20–30 leaflets.
- Bark: Rough, fissured, brownish-grey.
- Flowers: Small, white, fragrant, and in clusters.
- Fruit: Smooth drupe, yellow-green when ripe.
- Roots: Deep taproot with extensive lateral roots.
5. Environmental Benefits of Neem Tree
- Air Purification – Absorbs carbon dioxide and releases oxygen, improving air quality.
- Soil Improvement – Neem leaves and seed cake enrich the soil with organic matter.
- Shade and Shelter – Provides shade in hot climates and shelter for birds, bees, and insects.
- Erosion Control – Strong roots prevent soil erosion.
6. Medicinal and Practical Uses of Neem
A. Medicinal Uses
