I have a miniature tangerine tree or I guess you could call it a dwarf tree, I have grown it inside the house for about 20 years, and put it out in the summer. My question is, it's suppose to produce fruit and it doesn't. Does anyone know why? I was at one forum that said there has to be a certain number of leaves on it, well I have well surpassed that years ago, and it still won't fruit. I got to thinking that maybe it's like an apple tree you need 2 of them to cross pollinate? I don't have room in my house for 2 plants this size, so is there anything I can do to make it fruit?
