How long until my trees produce fruit?

[TreeBeard]

I have several acres of land in which I planted different types of fruit bearing trees; this was three years ago and I’ve not gotten any fruit from them yet. I planted cherry, three different types of apple trees, plumb, and pear trees; none of them have produced any kind of fruit, however they do bloom every year. I’m not an expert in the field; I just wanted to have some fruit trees so I could reap the benefits of the fruit to make jams, jellies, and pies. Three years now and I have to go to the grocery store to buy fruit. Is there something I am doing wrong? I figured by now I should be getting some kind of fruit from them and wondered if it might have something to do with pollination or something like that. Can you give me some good advice about my fruit trees that aren’t giving me any fruit?
