There are few special methods
and practices In the management Of
peach orchards which are of sufficient
Importance in some sections to justify
brief reference to them.
The Ohio agricultural experiment
station has called attention to the eff
cacy of slightly mounding up the soil
about the base Of the trees in pre-
venting injury during periods of ex-
cessively low winter temperatures. In
the same connection 1t has been
shown that various other factors re-
iating to the soil may greatly influence
-he amount of damage which peach
trees suffer during such periods.
The winter of 1904 was character
fzed in the Lake Erie peach district Of
Ohio by periods of severe and pro-
ionged cold Great number of peach
srees were killed. The prevailing con-
iitions and their attendant results on
the peach trees are summarized as fol-
lows:
Exceptional causes of susceptibility
20 cold in rare cases OF apparently
healthy, vigorous trees: Low. moist,
rich black soil which favored an ex-
IRENE growth OF soft. poorly ripened
or matured wood; or high culture upon
soil rich In plant food which brought
about similar results.
The unusually deep, hard freezing
Of the earth's crust was due. directly,
TO the continued, steady cold, but was
intensified. in many instances. by a
lack OF humus or vegetable matter in
the soil. which constitutes natures in
sulation OF the surface of the earth
from cold and heat
Providing that the orchards had been
Kept free from fungous disease and
the San Jose scale by timely and thor
ough spraying. no injury OF trees was
found where sable or barnyard ma
nure had been used upon the ground
within the last year or two previous
TO the winter OF 1904; rarely was an
injured tree found standing in sod;
no injury was done where the surface
of the soil beneath the trees had been
covered with even very slight
mulch: little injury was done where
the trees stood in fairly well drained
soil containing n moderate amount OF
fertility and humus: no injury was
found where the trees were under the
grass-mulch methods OF culture =:
no injury was observed In any case
where the stems OF the trees had been
slightly banked or mounded with a
few shovelfuls or forkfuls of soil. peat.
or manure.
Very few trees which. within the
past years. had been affected with leaf.
curl or infested with San Jose scale or
borers remained alive or unInjured;
and very few trees existing upon in.
fertile or exhausted soil. depleted OF
humus. escaped minlured,
The usefulness OF cover crop IN
preventing the washing OF the soil
during the dormant period OF the
trees Is frequently well demonstrated
Moreover In some regions where the
winters are rather severe and there is
very limited snowfall. cover crop
prevents the snow from blowing away.

against the extreme freezing OF the
