Es its natural upward growing habit. Plant food is taken up by the

minute tree rootlets in solution
and carried to the leaves where it is
elaborated and then returned for use to the growing tissues of the
tree. Whenever
there is any obstruction above a bud the tendency is to throw the
energy of the branch into a lateral bud, but if the obstruction
is below the bud the branch merely thickens and growth is checked.
When too heavy pruning is practiced the balance between the roots and
top is disturbed. This usually results in what are commonly known as
"suckers." These are caused by an abnormal

condition and while they may be the result of disease or injury

to the tree, they are often of great value in restoring
or readjusting the proper balance between the roots and top.
Pruning a tree is a way of thinning the fruit and a good one. It may
sometimes be used to influence the
bearing year of trees like the Baldwin, which have an alternate
bearing

habit, but this is a more theoretical than practical method. Fruit
bearing is determined more by the habitual performance of the tree
than by any method of pruning, and this is especially true of old
trees. It is easier to influence young trees.
Conditions which tend to produce heavy wood growth are unfavorable
for the formation and development of fruit buds. A quiescent state is
a better condition for this. REASONS FOR PRUNING.--With these
fundamental principles in mind we may safely outline a method of
pruning an apple tree. As the desired end is different

so will the method of pruning a young tree differ from that of an old
one. There
are five important things for which to prune a young tree, namely: 1.
To preserve a proper balance between the top and root at the time of
setting out. This usually means cutting
