I can sympathize with you Robert, I have an orange tree 7 yrs old that does the same thing. Maybe it needs another of a different sex? I've decided that if mine doesn't bear fruit this year

up it comes! I've given it fair warning, this year or out. I have a neighbor who says I should beat it with a stick?

I've heard that once or twice b-4, maybe as a last resort I'll give it a good beating.
