FRUIT GROWING.

By P.H. FOSTER.

In the first place, if you contemplate appropriating a portion of your

land for the raising of fruits, you should have the orchard so situated

that no large animals can run at large on the grounds. Prepare your soil

in the most thorough manner; underdrain, if necessary, to carry off

surplus water; dig deep, large holes; fill in the bottom with debris;

in the very bottom put a few leaves, clam and oyster shells, etc., then

sods; above and below the roots put a good garden or field soil; do not

give the trees fresh manure at the time of setting, but the following

fall manure highly with any kind on top of the ground; dig it in the

following spring; keep the soil frequently worked during the summer,

and, if convenient, mulch with hay, straw, or leaves.

Now you are on the road to progress, provided you have made no mistake

in the selection of your trees. The purposes for which you intend your

fruit is highly important. You should well consider at the outset if

for family or market use. This is a business which requires a long look

ahead, for it is said, "He who plants pears looks ahead for his heirs."

Caution should be used in procuring your stock; little should be planted

that is not fairly tested on the Island, purchased of parties who can be

fully relied upon to give you what you want. Do not buy your stock of

parties who carry labels in their pockets to make to order what you want

out of the same bundle of trees.

Now, having your trees set out in a proper manner, of such varieties

as you desire, the next important step is to bring the trees into

usefulness. My plan is to use bone--fine bone--very freely about every

three years. Another important matter is that of trimming. "Fire

purifies," and the knife regulates the grand balance or equilibrium

between roots and tops. In most cases the top outgrows the roots, the

consequence of which is an ultimate weakness of the tree. It is thrown

into excessive fruiting, disease, and premature decay. To avoid this

result, use the knife when required. Thin out the inside branches when

small, and if the tree does not make a satisfactory growth, cut back

half way to the ground.

We will suppose that you have got your trees growing nicely, and they

have begun to bear fruit. There are other important steps to be taken,

which will be of little cost to you. Provide a wind-break for the

orchard. Evergreens answer the purpose, being a protection against the

wind. Having this matter attended to, there are other enemies with which

we must contend. I refer to the apple and peach tree borers. The former

will live in the tree for three years, if unmolested; the latter, one

year only. They are very easily destroyed by looking over the trees and

taking them out with a knife; or maybe prevented from touching the trees

by wrapping a piece of felt paper, 8 inches wide, around the tree near

the ground, the bottom being covered with dirt and the top tied tightly

above. The pear is not generally disturbed by these insects--only the

apple, peach, and quince. We have another insect very destructive to the

plum, peach, cherry, and apple--the _curcutio_, or plum weavel. This

season for the first time in twenty years we have gathered a small

crop of that very desirable plum, the Purple Favorite. We simply threw

air-slaked lime over the trees nearly every morning for from four to six

weeks, from the time the tree was out of bloom. Peach trees should be

treated in the same manner. Another method of fighting this insect is to

spread a sheet under the tree, and with a blow jar off the little Turk

and secure him on the sheet. But I consider the lime procedure the less

trouble and more effective. The tent caterpillar, which is easily seen,

should be destroyed at once. We have yet another insect to contend with

which infests the apple and pear, commonly called the Coddling Moth,

and the larva, the apple-worm (_Garpocapsa pomonella_). The loss by the

ravaaes of this insect alone to the fruit growers of the United States

fan hardly be estimated, as in many cases the whole crop is rendered

worthless. Such a vast destruction of two of the most valuable fruits

the world produces should stimulate scientists in this age of progress

to discover an effectual remedy against such a gigantic evil.

I have never yet discovered nor tried an effectual remedy against this

insect. The nearest I have approached his extermination is in the

following manner: After it has entered the fruit and accomplished its

damage, the time arrives when it has to leave the fruit and hide itself

in a quiet, secure position to undergo the transition from the larva to

the pupa state, which requires, in the early part of the season, eight

or ten days; after this time the miller is hatched and is again ready to

besiege the fruit with its sting. The insect, being two-brooded in this

climate at least, if not disturbed, has an aggregating force to do

mischief the second time. The progeny for the succeeding year have alone

to depend on the security of this second generation of larvæ. As they

may often be found in bark of apple trees during winter, my plan of

destruction is, about the first of July to take woolen rags long enough

to wrap around the trees, and say four inches wide. Each week I look

over the trees, and destroy the worms secreted under the rags and

wherever I find them until the fruit is off the trees. I have all the

green fruit, of every kind, carefully picked up as soon as it falls,

thereby destroying many of the curculio as well as the apple-worms.

One word upon the grape--the insect part of the question. The

_Phylloxera vastatrix_, or grape-vine louse, is already at work on Long

Island. It is found very difficult to raise many of our fine, new grapes

with us in consequence of the depredations of this very minute insect,

it being almost too small to be seen by the naked eye. There has lately

been discovered a remedy which is entirely chemical and as yet but

little disseminated. Very soon, no doubt, a discovery will be made that

will stay the progress of this destructive enemy.

We should plant aplenty of cherry and small fruit trees to yield feed

for birds. In return they will assist us in our efforts to preserve a

bountiful supply of this health producing element.
