their growth is checked. When such a wound does occur, or if a wound
is made by cutting off a branch, the cambium sets to work to repair
the damage by pushing out a new growth which tends to cover the wound.
We can help this by covering the wound and keeping the air from it to
prevent its drying and to keep disease from attacking it before it is
healed.


HOW THE WORK OF THE STEM MAY BE INTERFERED WITH

If there are any peach trees near by, examine the trunks close to the
ground, even pulling away the soil for a few inches. You will very
likely find a mass of gummy substance oozing from the tree. Pull this
away and in it and in the wood under it will be found one or more
yellowish white worms. These are tree borers. They will be found in
almost all peach trees. They interfere with the work of the stem and
in many cases kill the trees. These worms may be kept somewhat in
check by keeping papers wrapped about the lower part of the tree. But
the surest way to keep them in check is to dig them out, spring and
fall, with a knife and wire.

Borers attack the other fruit trees and also ornamental trees and
shrubs.

Rabbits sometimes gnaw the bark from trees during severe winters.

Careless workmen sometimes injure the bark of trees by allowing plows
and mowing machines or other tools which they are using among them to
come in contact with the trees and injure the bark.
