Exposures for the Cherry. 217 
presses the frujting function. Usually these trees will ultimately 
bear when their exuberant growth declines. They can be 
thrown into fruit sooner by root pruning, digging a trench 
around about eight feet from the tree, and severing the roots thus 
encountered, or by summer pruning of twig ends. Because of 
this overgrowth, growers give such soil to the apple or the pear 
rather than the cherry. Sometimes the non-bearing of the 
cherry is inexplicable. Though everything seems to be rght, 
and the blooms are profuse, the fruit will not stick. Some 
think it is due to lack of association oi different varieties and 
cross fertilization. It is held at Vacaville that keeping bees in 
the vicinity of cherry orchards has increased the bearing. 
EXPOSURES FOR THE CHERRY, 
Exposures for the cherry are chosen both with reference to 
protection from frost injury and to early ripening of the fruit. 
The cherry blooms early; it is almost as venturesome as the 
almond. In protected situations, guarded from cold northerly 
winds, and open to sunshine on the south and southeast, the 
fruit advances to maturity very rapidly. In Vaca Valley about 
a month of good weather alter the biossoming will ripen an 
early cherry. The pioneer cherry growers of Vaca Valley went 
there from their old homes in Napa Valley, because they could 
gather and market cherries in their new locations before the 
same varieties were ripe in Napa. They chose places protected 
on the north and west by steep hills. ‘The two things to secure 
are, apparently, protection from the sweep of cold winds and 
elevation above the deposit of cold air, which occurs in depressed 
places. 
In localities where fruit ripens late, as near the coast, there 
is no need to seek forcing conditions, for the extra early varieties 
should not be planted except for family use. Early varieties 
are comparatively poor in quality, and will not sell profitably, as 
they will reach the market alongside of better later sorts from 
earlier districts. The place for the cherry in the later districts 
is on the most proper soil, according to the requirements which 
have been laid down, avoiding, however, so far as possible, wind- 
swept spots, and seeking amelioration of direct ocean influences 
by elevation or intervention of hills and windbreaks. 
PROPAGATION AND PLANTING THE CHERRY. 
In the chapter on propagation is given a successful method 
of growing cherry seedlings. California cherry trees are al- 
most exclusively propagated by budding on seedlings of the 
Black Mazzard. ' 
The planting of the cherry is covered by the general con- 
siderations already given for the planting of orchards. The
