+ In mixed plantings with apple, if Pear Psylla is not the chief 
insect pest follow the same general spray schedule as for 
apple. 
+ This spray may be omitted, if Pear Scab and Pear Midge are 
absent. 
§ This spray may be omitted if Psylla infestation is very light. 
Caution — As arsenical sprays are poisonous to humans and 
warm-blooded animals, care should be taken to prevent it 
from coming in contact with leafy vegetables in nearby gar- 
dens or in any way being ingested. 
PRUNING AT TIME OF PLANTING 
The great majority of people do not take proper care of their 
trees after they are set in the ground. This is a great mistake. If 
a tree does not receive the right kind of care, and enough of it 
when young, it will never attain a perfect shape and healthy old 
age. The top of the tree is pruned to restore a near balance be- 
tween the crown and root area. Pruning gives the tree the proper 
framework for future development. 
When pruning small limbs, make the cut slightly above the 
bud, in a diagonal position to shed rain. Also, avoid cut too far 
from bud or too close to bud or on the bud. 
PRUNING APPLES - PEARS - PLUMS - APRICOTS 
These varieties require little pruning when young. Fruit trees 
that are pruned too much when young are usually late in coming 
into bearing. All of the pruning that such plants need is the 
removal of branches that are too close together for the develop- 
ment of a well-balanced top. A slingshot crotch at the top of the 
tree should be eliminated to prevent tree from splitting—remove 
weaker branch, the trunk which continues is shortened by about 
1/3. The lateral branches are shortened only where necessary 
to give the tree a balanced pleasant shape. 
Where there is a whorl, remove branches to make a single 
dominant leader which becomes the new trunk. 
The remaining branches are equally spaced up and down and 
around the trunk. They make wide angles with the trunk which 
will develop strong crotches. 
Also, where there is an oversized branch or bruised branch 
which gives the tree a one-sided appearance, cut them back to the 
size of the other branches. 
; After fruit trees come into bearing, more pruning can be 
given than in the first years after setting. 
PRUNING CHERRY — Of all fruit trees, cherries have the 
greatest amount of vitality when transplanted. Often, a good 
percentage of all unpruned cherry trees are killed, but pruning 
will reduce this great loss considerably. Cherry trees are also 
subjected to losses if planted at the improper time. Fall is a good 
time to plant cherry trees. However, we specially prepare our 
cherry trees to keep the roots well protected from drying during 
the spring. Avoid planting cherry trees in an advanced stage. 
1 year old cherry trees should be reduced to 2/3 their size. 
Zor3 year old cherry trees are puned by thinning out their 
lateral or side branches, to prevent crowded head and develop 
desirable spacing of wide single lateral branches. Cut out lateral
