The Tropical Fruit Forum

I have a Kari starfruit, at least it was sold as a Kari. It is about 3 years old and has never set fruit.  I wasn't too concerned the first few years because it was small, but now it has a nice size on it and it still won't fruit. It has bloomed frequently and in large quantities. It looks healthy. It is in partial shade. I am frustrated. Does any one have any advice? I heard some starfruit are not self pollinating, but Kari is supposed to be. I don't really have room for another starfruit tree.
