PROF. IHoRNBER'S SUGGESTIONS

plant that has or has had crown
gall. If, however. the tree is found
to have it and it appears vigorous,
| would treat with lime by apply
ing from one-half bushel to one
bushel of air slack lime to the soil
around each tree, and give the tree
a chance to outgrow the difficulty.
If the disease girdles the tree, then
the only thing to do is to remove
the tree and before replanting the
soil should be treated to one bushel
to one-half a bushel of air slack
lime.
Imperfect Observation-Disclosures
feet polarization causes a great
many cherries and, for that matter,
stone fruits of all kinds to drop
from the trees after the fruit is
nicely formed. This difficulty is
due to lack of sufficient pollen COM
ing in contact with the flowers when
they are in blossom. 1t may be
due to weather conditions, to lacI
of insects or the trees themselves not
producing sufficient pollen.
Treatment-The only remedy for
this consists in top budding other
varieties in the bearing trees or
planting two or three varieties that
blossom at the same time rather
than one variety. There is nothing
that can be done when the fruit
starts to drop as it is then too late.
Shot Hole Fungi-The shot hole
fungi is fungus disease showing
up in several different forms upon
most of the stone fruits. In this
particular case it was on the sweet
cherry and showed very nicely how
the disease spreads from tree to
tree as it progresses from year to
year. The early and most common
stage of this disease is the Kidding
Of the leaves as if they had been
shot with bird shot. The second
stage shows the second year on
trees with small yellow foliage and
poor growth upon these particular
limbs effected, and the third year
the tree usually starts to die back.
After the tree starts to die, the gum
usually commences to ooze from it
and unless it is in very vigorous
condition generally, there is very
little chance to save the tree.
Treatment-The treatment of the
disease when it first appears, con-
sists of spraying with ordinary Dor
deaux mixture. This spray should
be applied Immediately after the
fruit Is picked. The second stage
of the disease is best treated by
pruning out diseased parts and then
by thoroughly spraying the tree,
after the leaves have fallen in the
fall, with double strength bordeaux
mixture or very strong lime sulphur.
While the trees may be seriously
effected, it can be entirely cured of
the difficulty by rigid, careful treat
ment.
Foliage too dense-One orchard
examined showed that the trees had
failed to produce any fruit for the
past two or three years, in fact,
the fruit buds and fruiting twigs
had all disappeared from the center
of the tree. The soil seemed to be
in fairly good state of cultivation
and the trees were very vigorous.
The difficulty in this particular case
is that the trees have produced 80
much foliage that the inner
buds and fruiting twigs have been
shaded so completely as to have de-
stroyed them. One of the essen
tials of strong fruit buds is plenty
of sunlight. While most of the
trees are producing few cherries
on the outer limbs, yet the growth
even on the edge would so OCCASION
ally cover these buds that they did
not get a chance to fully develop for
the following years crop.
Treatment Immediately after
the cherries are harvested, the tops
should be cut back and thinned
out. Remove from one-eighth 20
