Neem (Azadirachta indica) is a tree that is native to India. Its seeds, bark and leaves have been used extensively in Aryurvedic medicine for several thousands of years. Indians there call Neem 'the village pharmacy' and depend on its medicines for all types of skin problems, as an antimicrobial and and anti-inflammatory. Its tender shoots and flowers are also eaten as a vegetable. Neem oil, which is pressed from the olive-like seeds (see photo above), is a very effective bio-insecticide for garden plants. Neem doesn't actually kill chewing insects, but interferes with hormonal processes so the bug forgets to eat and/or reproduce. It does not affect pollinating insects, however, because they do not chew on plant leaves. You won't notice results right away, so do not think it is not effective. Be patient, as it takes about a week to see results. I can actually see my lettuces and Echinacea plants growing new leaves without big holes being chewed in them.
