Return to top Neem , Azadirachta indica. Technical Available . Neem is a fairly fast growing tree and is medium in size when mature. The seeds, and to a lesser extent the leaves, contain azadirachtin. This is a systemic pesticide with both repellent and insecticidal properties.
Seed production starts in five years or less.
Sometimes we have grafted neem so the rootstock and grafted branch can pollinate each other. The seeds can be ground up and soaked overnight, then strained and the liquid mixed with more water and sprayed on gardens. A commercial neem insecticide is now on the market called 'Margosan'. The wood is similar to Cuban mahogany and is tougher than teak. It is rot and insect resistant.
