I want to plant some apples, peaches, an apricot and a pear maybe some cherries. What is the difference between self pollinating and the ones that need a pollinator. Well, besides the obvious--does one kind have more or better fruit than the other? There are 5 in our family, will a dwarf fruit tree produce enough for us? Are there certain things I need to look for? I don't know anything really about fruit trees. I don't have alot of space though so nothing too large. I like cherries, but was hoping to find something naturally sweet. My MIL has some cherry trees, but the fruit is so sour it takes a load of sugar to make it edible.
