you assign to them, probably. Pears can be more successfully kept down
than apples, but not to ten feet except as dwarfs.



Pruning Old Apple Trees.



How would you prune apple trees eight or nine years old that have not
been cut back? There are a great many that have run up 20 feet high with
twelve or fifteen main limbs and very few being more than two or three
inches in diameter.

Remove cross branches which are interfering with others and thin out
branches which seem to be crowding each other at their attachments to
the trunk, by removing some of them at the starting point. Having
removed these carefully so as not to knock off spurs from other
branches, study the tree as it is thus somewhat opened up and see where
remaining branches can be shortened to overcome the tendency to run too
high. Do not shear off branches leaving a lot of stubs in the upper part
of the tree, but always cut back a main branch to a lateral and shorten
the lateral higher up if desirable. This will keep away from having a
lot of brush in the top of the tree. Study each tree by itself for
symmetry and balance of branches and proceed by judgment rather than by
rules anyone can give you.
