The neem tree (Azadirachta indica) has caught the attention of gardeners in recent years for the benefits of its oil, a safe and effective herbicide. This versatile plant is native to tropical India and Asia.
 
Neem is a hardy tree that can tolerate temperatures up to 120 F. (50 C.). However, extended cool weather with temperatures below 35 F. (5 C.) will cause the tree to drop its leaves. The tree won’t tolerate colder temperatures, wet climates or prolonged drought. Can grow indoors in a pot filled with good quality, well-drained potting soil. 

Planting Season: Spring and early summers in a cold climate. But anytime in a warm, tropical climate.
 
Neem trees require plenty of bright sunlight. The trees benefit from regular moisture, but do not overwater, as the tree won’t tolerate wet feet or poorly drained soil. Allow the soil to dry between every watering. Because of their unique insect repelling qualities neem trees don't have any problems with sucking or otherwise damaging insects. People actually grow them in the hope to repel pests and protect other house plants.
 
Cultivation: Prepare fertile, well-drained soil. Transfer the plant in late spring/early summer (soil temp at least 60°F) in a warm and sunny location. The plant is being grown in the greenhouse for approximately 6 – 8 weeks. Keep soil moist. Fertilize as needed. Train to climb a vertical support for better air circulation and ease of harvest.

Please note: Maturity, adaptability and disease tolerance may differ under your specific climate and/or growing conditions.
