Once something only available to certain exclusive gardens, dwarf fruit trees can now be planted by anyone, and they won't cost you a fortune. Dwarf trees, which typically grow to 6 - 8 feet in height, are produced by grafting or budding standard varieties on special dwarfing rootstocks. In addition to being a more manageable size, another advantage of dwarf fruit trees is they begin to bear full size fruit in only two or three years.
