What is Neem Oil?

Neem oil is a natural oil extracted from the seeds of the neem tree (Azadirachta indica). It contains azadirachtin, a compound known for its insecticidal and antifungal properties. Neem oil is commonly used to combat pests like aphids, whiteflies, spider mites, and fungal diseases such as powdery mildew.

Safety Considerations:

1

Use Cold-Pressed, Organic Neem Oil

This type retains the beneficial compounds and is safe for edible plants.

2

Dilution is Key

Always mix neem oil with water and a mild emulsifier (like dish soap) before spraying.

3

Apply at the Right Time

Spray neem oil in the early morning or late evening to avoid harming beneficial insects like bees.
