The method of setting or the arrangement of the trees
will greatly influence the number of trees which may be put upon an
acre and the distance apart of the trees in the row. The most common
method in the past has been
the regular square or rectangular method,
e.g., trees forty by forty feet, or forty by fifty feet, and rows at
right angles, and this is still preferred by many. It is easy to lay
out an orchard on this plan and there is less liability of making
mistakes. It is best adapted to regular fields with right angle
corners, especially where the orchard is to be cropped with a regular
rotation. All tillage operations are most easily performed in orchards
set on this plan.
A slight modification of this arrangement which is often advisable,
especially where fillers are used, is to set a tree in the center of
the square. The trees then stand like the five spots of a domino, and
the shortest distance between trees will be about twenty-seven feet
when the trees in the regular rows are forty by forty feet apart. This
plan practically doubles the number of trees which can be set on an
acre.
