I have this Neem tree and was told that they are gender specific. I have tried looking on the internet to no avail. Is there an easy way to identify the gender of a Neem tree?
They are not gender specific - each cluster of flowers bears both male and female flowers, but an individual tree is not capable of pollinating itself. Fruit production is normally low, but increases with hand pollination; if you only have one tree and there are no others in the vicinity, you probably need to plant at least one more.
