What plants should I not use neem oil on?
Neem is a pesticide that is produced naturally from the seeds of the neem tree (Azadirachta indica). Tropical woods in Burma, India, and Sri Lanka are home to neem trees.

Azadiractin is exclusively found in commercial insecticides and is used to alter the hormones that control insect growth and reproduction. The active ingredient in ready-to-use neem oil sprays that may be purchased at a garden center is clarified hydrophobic neem oil.
