Uses

Azadirachta species, particularly Azadirachta indica, have been used in traditional medicine for centuries. The leaves, bark, seeds, and oil of the Neem tree are used for their antibacterial, antifungal, antiviral, and anti-inflammatory properties. Neem oil is also used in agriculture as a natural pesticide and insect repellent.

Cultivation

Azadirachta trees thrive in well-drained soil and require full sunlight. They are drought-resistant and can tolerate poor soil conditions. These trees are commonly propagated by seeds, which should be sown immediately after collection for the best germination rates.

Ecological Importance

Azadirachta trees play a significant role in their native ecosystems. They provide habitat and food for various species of birds, insects, and other wildlife. The trees also help in soil conservation and can improve soil fertility through the addition of organic matter from fallen leaves.
