Reading edition
"Dwarf Trees.—Are produced by propagating the Sweet or Duke varieties on the Mahaleb, or Morello roots. They should in all cases be worked just at the crown of the root, as it is there a union is best formed; and also, by means of pruning, (see page 30) they should be made to form heads branching immediately from the ground." Elliott Fr. Book 1854:185.
