Trees, Fruits and Flowers of Minnesota Part 32

BEWARE BLIGHT CURES.--Almost every year orchardists are persuaded to try some new, so-called "blight cure" or preventative, only to find later that they have wasted time and money in the experiment.

Government regulations regarding fake remedies of this character are more strict than formerly, but there are still some agents trying to dupe the public into buying their wares.

Blight, which is often referred to as apple blight, fire blight, or pear blight, is caused by bacteria which live in the sap of the tree, and the principle followed by the blight-doctor is to introduce something into the sap which will prevent the working of the bacteria. The remedies are applied in various ways. Sometimes the trunk is painted with a mixture of some kind, or holes are bored into the trunk and these filled with a powder. The orchardist is sometimes furnished with a box of nails as the first "course" and instructed to drive these into the roots of the trees.

It is evident that anything introduced into the sap that is strong enough to kill the bacteria living there will likewise damage the cell tissue of the tree, and result in more harm than benefit. One powder that has been brought to the attention of the Experiment Station, sells for $3.00 per pound, and is administered in teaspoonful "doses." Such a preparation as this is probably harmless, but is a waste of time and money. It would have no effect on the tree or the blight.

Some of the agents not only claim that their remedies will cure blight, but, due to ignorance or other causes, they also claim that trees treated will be immune from attacks of certain insects.

Orchardists may rest a.s.sured that up to the present time, no real preventative or cure has been found for blight, and that the only way it can be controlled is by cutting it out.--Colorado Agricultural College.

IN MEMORIAM--MRS. E. CROSS.

Mrs. Erasmus Cross, of Sauk Rapids, and a member of the Minnesota State Horticultural Society since 1888 (27 years), pa.s.sed away at that place on Tuesday, December 28th. On December 16th Mrs. Cross sustained a painful injury by falling on the floor and breaking her hip. Owing to her advanced age, eighty-two years, the limb could not be set without the use of chloroform, which could not be given on account of weakness of the heart. Death finally released her from her suffering.

[Ill.u.s.tration: The late Mrs. E. Cross, daughter and grandaughters.]

Mrs. Jane Cross was always very enthusiastic about the Horticultural Society and the good it was doing, not only for this but other states.

The ills of her age had prevented her from attending the meetings these late years, though she often did so in earlier years, but she always sent her fee through the writer, and eagerly awaited her return from the meeting to hear of its stimulating success. Mr. Cross died about six years ago. Two sons, James, of St. Paul, and Robert, of Sauk Rapids, and two daughters, Mrs. Annie Nicholson, of Hamline, and Mrs. Emma Sovereign, of Sauk Rapids, mourn her loss. Our society has lost a most loyal friend.--Mrs. Jennie Stager, Sauk Rapids.

Notes from Prof. Alway's interesting and instructive talk on "Maintaining the fertility of our gardens."

Requisites for proper plant growth are warmth, ventilation, root room, the absence of harmful alkalies or animals that destroy the beneficial bacteria in the soil, water and plant food.

By far the most important requisite for growth is water. More plants and crops fail because of the lack of a proper amount of it than from any other cause.

Plenty of fresh air is needed by the plants, as they derive a portion of their food from it.

They adapt themselves largely to conditions as to root-room, a plant thriving in a pot, but spreading to much greater root s.p.a.ce when grown in the open with plenty of room. The more restricted the root s.p.a.ce, the more food and water it will require.

The fourth requisite for growth does not concern us as there are no alkali lands in the counties near the Twin Cities, and the harmful minute animals that destroy the beneficial bacteria in the soil are as a rule found only in greenhouses.

The best fertilizer for the garden is the thorough use of the hose.

Each year stable manures become harder to obtain, but the fertility of the garden can be maintained by the use of commercial fertilizers, which are more concentrated foods and are much easier to work with.

The perfect plant food consists of nitrogen, phosphorus and potash. We can obtain these in separate form and use as we need them.

Nitrogen comes in the form of a salt, called nitrate of soda, and in dried blood. The nitrate of soda is very soluble in water and is taken up at once by the plant. It can be scattered upon the ground near but not touching the plant, as in the latter case it would burn it. It can also be dissolved in water--a tablespoonful to a pail--and the ground, but not the plant, watered. Dried blood is slower in action and requires warmth, so should not be used early in the season. Nitrogen promotes quick and luxuriant growth of leaves and stems and is good to use when a green growth of any kind is wished.

In bone meal we find the phosphorus necessary to aid in the development of fine and many flowers, to expand root growth and to hasten maturity.

It works slowly, so can be applied to the ground about a plant early in the season, and will be available in the ground the following year if enough is used. Equal parts of nitrate and bone meal can be used at the rate of one to two pounds to every one hundred square feet.

Potash is almost off the market, as a result of the war, the main supply being imported from Germany. It can be obtained from hardwood ashes, and every bit of these should be saved for the garden and stored in a dry place where they will not become leached out by the action of water.

_April Spraying._--s...o...b..ll bushes and others that have been troubled with aphides, or plant lice, the previous year should receive a thorough spraying of Black Leaf No. 40 (an extract of forty per cent. nicotine) before the leaf buds expand. For this early spraying, two tablespoonsful of the extract can be used to every gallon of water. It will stick to the branches better if some soap is dissolved in it. This spray will kill most of the eggs of these pests, which will be found near the leaf buds. When the leaves open another spraying should be given to kill all those that escaped the first treatment. For spraying after the leaves open use one tablespoonful to each gallon of water.

BEE-KEEPER'S COLUMN.

Conducted by FRANCIS JAGER, Professor of Apiculture, University Farm, St. Paul.

Bees are kept both for profit and for pleasure. The old fas.h.i.+oned beekeeper with his hybrid bees, kept in immovable hives, logs or boxes, did not derive much profit from his bees. He kept them mostly for pastime. During the last fifteen years men with new methods of management and modern equipment have been rapidly superseding the picturesque old beekeepers. Modern beekeeping courses are now taught in connection with our inst.i.tutions of learning, and young men full of energy and ambition are beginning to realize that beekeeping is offering one of the few opportunities to make a comfortable living with a comparatively small expense. Older beekeepers, both on the farm and professional men, also are beginning to study beekeeping. They attend short courses, subscribe to scientific bee papers and study bee literature. With increased study and knowledge the whole status of the beekeeping industry is just now undergoing a rapid change. Professional beekeepers, men who devote their whole time to beekeeping, are increasing, and more amateurs are turning to professional beekeeping every year. Organizations of beekeepers now exist in nearly every state.

Their object is to spread knowledge among their members and to secure better prices for their product by co-operative marketing. Contrary to fears of more conservative beekeepers the demand for a first cla.s.s article of honey is increasing more rapidly than the supply. A national organization of beekeepers and bee societies is taking up just now national problems in connection with their industry and has succeeded in making the government interested in this "infant industry." An appropriation of $200,000 has just been allowed by the agricultural committee of the Congress to develop beekeeping in localities where help is needed. The state of Minnesota allows an annual appropriation for beekeeping interests of $10,000, divided among the following branches: Bee inspection department, which takes charge of bee diseases, $2,000; state fair exhibits for premiums and maintenance of a bee and honey building in connection with our State Fair, $1,500. The Division of Bee Culture at the University Farm, which has charge of teaching, demonstration, extension work, research, queen rearing, correspondence, statistics and model apiaries, $6,500. Minnesota beekeepers should be grateful to those men who have helped them to raise their industry from a mere nothing, until we have become the acknowledged leaders in beekeeping among all the states of the Union. They, however, are rapidly following, nearly all states now have efficient bee inspection laws, and twelve universities have followed our lead and have included beekeeping in their curriculum.

But we must not be satisfied with what we have accomplished. Out of $14,000,000 worth of honey which this state produces (by figuring) only $1,000,000 worth are gathered every year, and beekeeping in the state must grow to fourteen times its present proportions before it will be anywhere near its possibilities.

ORCHARD NOTES.

Conducted monthly by R. S. MACKINTOSH, Horticulturist, Extension Division, University Farm, St. Paul.

Minnesota orchardists are preparing for a full crop of apples this year.

From the experiences of last year with apple scab and codling moth, more thorough spraying is to be done. Senator Dunlap stated an experience he had in spraying that should be carefully considered by all apple men.

Nine rows of trees were sprayed on Monday or Tuesday. Owing to bad weather the other rows could not be sprayed until Friday or Sat.u.r.day.

What was the result? He had 175 barrels of No. 1 fruit from first part and only seventeen barrels of No. 2 in rows sprayed later. Some are planning their orchard work for the season along the following lines:

_First: Pruning._ To be done during the mild weather in March and April.

Thin out all dead wood, interlocking branches, water-sprouts and shorten others. Pruning is to get the tree into better form to sustain a large load of fruit, to open the center to permit sunlight to get in to color fruit, and to permit of better spraying. There are too many trees in Minnesota that have never been touched by knife or saw. Such trees need attention, but the pruning should not be too severe at any one time.

Begin this year to do a little pruning; next year do more; the year after a little more; and after that very little attention will be needed to keep the tree in good condition.
