People often grow these trees in pots which, restricts the root growth and therefore the height that the trees can attain.
However, if a tree naturally grows to such a height, keeping at a smaller size will have detrimental effects on the tree itself.
One option is to graft a branch from an existing tree onto some dwarf or semi-dwarf root-stock. Then you would be able to grow the tree in the ground without having to worry about it becoming to large.
