Winter Injury 
^^’eather conditions have killed and injure.1 more fruit trees than all other causes com- 
hmed. Wc consider the most dangerous season of the } ear to he in very early spring when we 
have bright, warm sunny days, followed by frosty nights, the warm rays of the run starts the 
sap on the south sides of the trees. These clear days of February and early March are followed 
by frosty nights, the frost clinging to the hark chills the freshly risen sap, which soon becomes 
sour, often bursting the bark on the south sides of the trees and causing a gum-like substance 
to issue forth. This is soured sap, caused by tha.ving and freezing and may he prevented to 
some extent by shading the south sides of the yo mg trees with a board or shake. These should 
he 5 inches Avide, 3 1-2 feet high, 1-2 to 1 in h thick, sharpened at one end and driven into 
the ground about 6 inches from the tree, alwa ,s on the south side so as to keep the sun rays 
from starting the sap prematurely. These protectors should be used for the first three years, 
after which the bark on the trees will have bee .me thicker and will better rvithstand the sud¬ 
den changes of temperature. The protectors may he removed during the summer months, or 
after danger of frosts is over. Sweet Cherry, Apricots and Peaches are the most easily affected. 
However, no harm will be done if the protectors are used on all young fruit trees. 
The Oregon Agricultural College advises a liberal coat of whitewash as a protection for 
orchard trees through the winter. This may be applied on the larger limbs as well as the body, 
hut in young trees would suggest that you also use the board or shakes in order to keep the sun 
off of the south sides, for we are certain that the premature action of the sap, caused by the sun 
is the start of the damage caused by the freezing that follows. By using both the whitewash 
and the boards, one would have double protection.
