fetal heat. The usual method of
supplying heat is by smudge pots,
but as long as there is an abundance
of Fighter" and cheap wood fuel in
this locality it will be preferable to
use wood fires.
The wood should be got ready In
the early fall and piled just outside
the grove. As soon as the time OF
frost danger approaches a pile of
wood should be placed in the center
of every square of four trees, max
ing about twenty piles Of wood to the
acre. Excepting in sharp freeze
it will not be necessary to light and
burn every pile at the same time,
but in temperature just little be-
low freezing it will bs sufficient to
fire only every other pile. A large
amount OF fuel should be right a.
hand to last through long freeze.
Spraying
There are quite number of pests
which injure the fruit or destroy the
trees, and II the grower has several
trees it will pay him to purchase the
materials and manufacture his own
sprays. In Farmers Bulletin No.
933 on Spraying Citrus Trees, /"
there is full information, but prob
ably we cal do service to those
who have not the time or patience
to do so much reading by quoting
the main; facts and recommendations.
The following are the best sprays:
For killing white flies and. scale
insects, boiled emulsion consisting of
paraf1in oil, gallons; water, l gal
lon; hard soap, pound. Instead of
hard soap e pounds OF fish-oil coap
may be used. Put oil, water and
soap into a kettle and heat to the
boiling point. While hot pump into
another vessel and then back again.
A hand spray pump is the kind to
use (something like bicycle pump),
but don't pump through more than
twice and don't pump after the liquid
has become cool.
For killing red spiders and rust
mites, use lime-sulphrr solution.
This is a mixture every farmer
should know how to make, and he
can call on the farm agent to teach
him how.
Trees to 4 years old require l
to / IL gallons of spray, and trees
ten feet In height require as much
as 10 gallons.
Never spray during rain or when
the leaves are dripping wet, as 1t
would run of and do no good.
Both upper and lower surfaces Of
the leaves and the branches and
trunk must be sprayed thoroughly.
In Florida the government rec
ommends four sprays a year: In
May with / per cent oil emulsion.
This means that the boiled emulsion
formula given above is diluted with
water to meke 200 gallons Of spray
material.
June to July apply lime-sulphur
solution, ! gallon of solution mixed
with SO to rs gallons of water for
spray. g-ss.@..
August Is to October 81, spray
again with / per cent oil emulsion
as above.
November or December spray with
solution as above de-
scrfbed.
The increased yield of the orchard
pays very large profits on the cost
Of the spray material and labor o.
applying It.
Cultivation.
In California before planting an
orange grove the ground Is plowcd,
then levelei for irrigation, and then
plowed again 20 inches deep with a
subsoil plow Mr.. Friedlander tells
me that where he has dynamited the
holes in which he sets the trees 1t
has been a very great advantage.
the trees grow faster and
healthier.
In Florida 1t has been found best
during the rainy season to grow
cover crops or a volunteer growth
Of grass and weeds, and In the dry
seasons with disk and harrow keep
up dust mulch to prevent evapOra-
lion of moisture. No green crop
should be plowed directly under, but
be cut and allowed to wilt On the
ground first:
In Florida on account Of their
light sandy soils they do not use
stable manrres. Here however this
ID probably the best fertilizer, al
;hough it should be supplanted with
fertilizers. No fertilizer
should be placed closer than a foot
II, more from the tree trunk, as It is
Injurious to the crown
