For pruning bonsai, one
could write many books. Bonsai is the name given by the Japanese
to dwarfed trees grown in containers. One of the difficulties in
most parts of the United States is how to carry them over the winter.
They must be kept cool enough to avoid the possibility of their
starting to grow before winter is over and warm enough to avoid
the danger of frost breaking the containers, some of which may be
valuable.
If you have a deep cold frame, a greenhouse,
or an enclosed porch in which the temperature averages about 45
degrees during the winter with artificial heat that will prevent
the temperature from going below 30 degrees and in the other direction
not more than 60 degrees and have the urge to grow Bonsai, you will
be justified in making an attempt.

First you should familiarize yourself with
the type of plant material favoured by the Japanese by visiting someone
in your neighbourhood who has a collection. Next consider the plant material
you plan to use. Some of this can be dug up from the wild or you may be
able to find suitable plants in your local nursery which you should be
able to obtain at reduced prices because they are not symmetrical enough
to warrant their sale as specimen plants.
Among suitable evergreens are the following:
Pinus sylvestris (Scots Pine), P. mughus (Swiss Mountain Pine), Tsuga
canadensis (Hemlock), and Chamaecyparis obtusa (Hinoki Cypress). The deciduous
flowering trees sometimes used include Prunus subhirtella (Spring Cherry),
P. serrulata ( Japanese Flowering Cherry), and P. persica (Peach).
Plants to be dwarfed are sometimes dug up
from the wild and potted or planted out in the cold frame. To compensate
for the loss of roots, the tops are carefully cut back, making the first
steps in shaping up the plant so that it begins to attain the form you
desire. The following year they will probably be fit to plant in their
permanent containers. These should be shallow with holes in the bottom
for drainage.
