Trees, Fruits and Flowers of Minnesota, 1916 Part 33

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.

While pruning look out for rabbit and mouse injury. If good trees have been injured do some bridge grafting as soon as you can. This means connecting the healthy bark above the wound with the healthy bark below.

Small twigs cut from the same tree, that are long enough to span the wound, are cut wedge shaped on both ends, and these ends put under the healthy bark. If possible cover the wounded area with earth. If too high up tie the scions in place and cover all cut surfaces with grafting wax and cloth. Several scions should be put in if the tree is large.

_Second: Spraying._ Three sprayings are needed on every bearing apple tree in Minnesota.

First spray: When the center of buds show pink. Don't wait too long.

Second spray: When the petals have fallen.

Third spray: Ten to fifteen days after the second.

Use lime-sulphur and a.r.s.enate of lead each time. It is important to do this at the right time, in the right way, and with the right materials.

Right is the word and not left-undone. Further particulars will be found on the page devoted to spraying topics.

_Third: Cultivation._ Follow the plan that is best suited to location.

This may mean sod, part sod and cultivation, cultivation and mulch, mulch only, or cultivation and cover crop. Doubtless the last is the best in most instances.

_Fourth: Thinning._ The thinning of apples in Minnesota has not been received with as much consideration as its importance demands. More attention will be given to this topic in subsequent issues.

HOME GARDEN.

What about the farm and home garden for 1916? Is the garden to receive the undivided attention of one or more members of each family, so that all members and guests may share its fruits? Let's make the home garden the best spot on every Minnesota farm in 1916. A conservative estimate of the actual value of the products from a half-acre garden is fifty dollars. In Minnesota there are over 150,000 farms. This would mean a total value of over $7,000,000. This does not include the value of the products of the village and city gardens. Careful estimates made in this state show that it costs about fifteen dollars for man and horse labor to take care of a garden of about three-fourths of an acre. Now for a BIG GARDEN MOVEMENT this year--for all the year. Not a big beginning kept up until the little weeds become big weeds. Is anyone going to allow weeds to outdo him?

NOTES ON PLANT PESTS.

Prepared by Section of Insect Pests, A. G. RUGGLES, and by Section of Plant Diseases, E. C. STAKMAN, University Farm.

Buy spray materials as soon as possible. The orchardist will probably notice very little difference in the price of his spraying materials, like a.r.s.enate of lead and lime-sulphur, as compared with last year; but those who still think that Paris green is the only good stomach insecticide, will be astounded by this year's price. At the present time, in one pound lots, the retailer cannot sell Paris green for less than 50c per pound--over twice what it was last year. In large quant.i.ties, it is doubtful if it can be purchased for less than 45c per pound. Fortunately a.r.s.enate of lead, a better stomach insecticide than Paris green, has not advanced materially in price, the powdered form being obtained for about 25c per pound. One and one-half pounds of this powder is used in fifty gallons of spray mixture. In our experiments, we have found a.r.s.enate of lead superior to Paris green as a remedy for potato bugs and all orchard insects. It is not necessary, therefore, to allow any injurious biting insect to live simply because Paris green is high in price. a.r.s.enate of lead, if properly applied at the right time, will keep any of these insects in check.

A dormant wash does little good in controlling scab. Hence, on account of the high price of spraying compounds, do not spray when unnecessary.

Many diseases of nursery stock are controlled by spraying. Begin spraying as soon as leaf buds unfold, with lime-sulphur 1-40 or Bordeaux mixture 4-4-50.

Copper-sulphate has also advanced 15c or 16c per pound. Lime-sulphur has not advanced materially; therefore, plan to use lime-sulphur or some of the made-up (paste) Bordeaux instead of Bordeaux mixture, whenever possible. _Potatoes can not be sprayed with lime-sulphur._

The aphis problem is usually a very serious one, because they are such persistent little breeders. The trees or shrubs most affected are roses, s...o...b..ll, currant, apple, plum and elm. The eggs of the plant lice pa.s.s the winter on the bark or buds of these plants and hatch as the buds begin to swell. Spray with the lime-sulphur (1-9) at this time. As soon as the leaves appear, spray with nicotine-sulphate as per directions on the container.

If plum pocket was bad last year, the trees should be thoroughly pruned.

Then spray with copper-sulphate, one pound to nine gallons of water, or lime-sulphur, one gallon with nine gallons of water, before the buds open. Follow with one to forty lime-sulphur or other spray as for brown rot. Control methods for plum pocket are not well worked out, so these methods cannot be depended upon entirely.

Be sure and look over the apple trees carefully; cut out and burn all cankers. Black rot has been increasing in the state, and since a great deal of early infection may come from cankered limbs, it is important that cutting out and burning be resorted to.

Last year the spring canker worm was just as active in the state as the fall canker worm; therefore, just as soon as possible, trees affected last year should be banded with the tree tanglefoot. The moths come out of the soil the first two weeks in April and at that time attempt to crawl up the trunks of the trees to lay their eggs on the limbs.

When raspberries are uncovered, be sure to cut out and burn all dead canes missed last fall. The gray bark disease and anthracnose, also snowy tree cricket and red-necked cane borer, are controlled in this way.

Plan to keep the young canes covered with a protective spray of resin-Bordeaux mixture. Try it on at least part of the patch. The benefit will not be apparent for a year.

Spray currants and gooseberries as soon as leaf buds begin to unfold, with either Bordeaux mixture 4-4-50 or lime-sulphur 1-40, to prevent powdery mildew and leaf spots.

For further information write to the section concerned. Inquiries will receive prompt attention.

SECRETARY'S CORNER

ANNUAL MEETING OF AMERICAN a.s.sOCIATION OF NURSERYMEN.--Information has reached this office to the effect that this national a.s.sociation will hold its annual meeting in Milwaukee June 28th to 30th. This is so near by that it ought to bring a goodly number of Minnesota nurserymen in attendance. For particulars in regard to the matter address John Hill, 204 Granite Bldg., Rochester, N.Y.

Pa.s.sING OF HANS KNUDSON.--Mr. Knudson, late of Springfield, Minn., was the originator of the Compa.s.s cherry, which has been generally planted throughout the Northwest these recent years. He grew this variety from a seed as a result of a handmade cross between the Miner plum and the sand cherry. Mr. Knudson had other seedlings of similar origin which we thought might be of value, but nothing has been since heard from them. News of his pa.s.sing early in January has just come to this office.

THE MCINTOSH RED.--I think the McIntosh is quite hardy as a top-worked tree; there are two in my old orchard set in 1894, and they have shown no signs of injury. They were grafted on crab whips, but they were planted on a knoll, that while clay was within twelve to fifteen inches of a deep bed of sand. They have been shy bearers, but I think on a clay subsoil, such as I now have, they might prove good bearers. I would not be afraid to risk them as to hardiness.--F. W. Kimball, Waltham, Minn.

REPORTS FOR MINNEAPOLIS MEMBERS.--Every member of the society is ent.i.tled to a copy of the annual report if desired. As there are not as many copies printed, however, as there are members, if every one asked for a copy we should be in trouble at once. Copies are mailed as promptly as possible after receiving membership fee to all members except those living in Minneapolis and those who come in as members of some auxiliary society. Minneapolis members are requested to call at the society office and secure the copy to which they are ent.i.tled, which will then get into their hands in a good deal better shape than though it pa.s.sed through the postoffice. Members of auxiliary societies are ent.i.tled to a copy of the report, but only upon the prepayment of postage, which would be seven cents to points within 150 miles of Minneapolis and ten cents outside that limit.

SCIONS FOR TOP-WORKING.--Stark Bros. Nurseries, of Louisiana, Mo., have sent to us for use in testing on top-worked trees a quant.i.ty of scions of the following varieties: King David, Jonathan, Delicious, Stayman Winesap, York Imperial and Liveland Raspberry. These scions are to be used primarily to fill orders for top-working from members who have selected them as one of the plant premiums, No. 8. There will, however, be a considerable surplus, we believe, and as far as they hold out we shall be glad to send them out to members of the society who have trees for top-working, and know how to graft properly, upon receipt of postage stamps to the amount of postage and packing, which would be approximately ten cents. We are not sure that we can supply all who may ask for them, but to a limited extent we can do so. I would suggest promptness in making application for these scions. Address Secy.

Latham.

WHO IS GROWING MCINTOSH RED APPLE?--Information from an interested member of the society is called for as to what success, if any, has been had in growing the McIntosh Red top-worked on hardy trees here in Minnesota. Scions of this variety have been sent out several years by the society and probably some have already come into fruitage, or perhaps they have been secured from other sources. Replies will be published. Address Secy. Latham.

NO PLANT PREMIUMS AFTER APRIL 1ST.--All members ordering plant premiums have undoubtedly noted this important condition that "all applications for plant premiums must be made prior to April 1st." This condition will be strictly adhered to, and those sending in selections for plant premiums after that date need not feel disappointed if they do not receive them. It is absolutely necessary to make a definite date beyond which no applications will be received in order to work out successfully the problem of distribution which faces us at that time.

TO MEMBERS OF AUXILIARY SOCIETIES.--Occasionally a member of an auxiliary society writes to this office asking for a copy of the annual volume of the society. Members of auxiliary societies are ent.i.tled to this volume, but the State Society does not pay postage on it, the amount received from auxiliary societies for memberships not permitting this expense. Any member of any auxiliary society who wishes to have a copy of the annual volume mailed from this office should send with the application postage at the rate of seven cents if within one hundred fifty miles of Minneapolis, and ten cents to points in the state more than one hundred fifty miles from Minneapolis.

BUY NURSERY STOCK AT HOME.--There are always more or less agents of foreign nurseries, that is nurseries located outside the state, canva.s.sing for orders of nursery stock in our state, and many citizens are also tempted to reply to advertis.e.m.e.nts of outside nurseries who are trying to secure business in Minnesota. It is not my purpose to condemn these outside nurseries nor their methods of doing business, which in most cases undoubtedly are honorable and straight forward. But there is a real advantage in buying nursery stock at home, that is, from nurserymen located in our own state, and especially from nurserymen who are in the immediate vicinity. There is no cla.s.s of goods that one can buy in connection with which there is such opportunity for mistake and fraud as in nursery stock. It is impossible for any but an expert to tell by the appearance of a tree or plant of any kind what the variety is, and either through mistake or purposely it is no uncommon thing for those purchasing trees to be disappointed as to the names of varieties when they come into fruitage or flower. If the nurseries are in our own state, or in our vicinity, it is a very easy matter to get at them, and they will almost uniformly be found willing to make good such blunders, or if they don't and the matter is worth while they can be made to do so. Don't place your orders outside of the state if the things you want can be purchased at home. You will find it a real advantage to act on this counsel. Especially in the case of strawberry plants the element of distance is a very important one as on account of their leafy character they heat and spoil readily. A few plants near home are often worth more to the recipient than a large shipment from abroad.

NURSERYMEN OF MINNESOTA.--The secretary endeavors to keep a correct list of all those engaged in the nursery business in this state.

As far as his personal acquaintance goes of course the list is known to be a correct one, but there are doubtless a number engaged in the nursery business in a small way of whom he does not know personally, and he would be glad to hear from any engaged in the nursery business who are not personally acquainted with him so that their names may be added to this list. The address of the secretary is always to be found on the front cover page of this magazine.

THE SOCIAL ELEMENT AT OUR ANNUAL MEETING.--Those of our members who attended the last annual meeting could not have failed to note the large proportion of ladies in attendance at these meetings, not only at the one managed by the Woman's Auxiliary, but also at every other meeting during the four days session. You may be surprised to learn that approximately one-third of those who registered as purposing to attend the meeting belonged to the gentler s.e.x, and the proportion in attendance was somewhere in that neighborhood. This is one of the delightful features of our annual gathering which is steadily increasing. More and more are the ladies attending our meetings, and in larger number are they becoming members of the a.s.sociation aside from any relation they may sustain as wives or daughters to those who are already members. This movement should be in every way encouraged, and we hope another year to be able to offer still more attractive accommodations in this direction. In planning for a new building for the society, this feature of our work should not by any means be lost sight of. I believe that very few organizations of this kind can boast so large an interest on the part of the ladies in the various branches of its work.

DID YOU SELECT EVERBEARING STRAWBERRIES AS YOUR PREMIUM?--An altogether unexpected demand has been made upon us for the Everbearing Strawberries the society is offering as plant premiums to its members this spring. Probably twice as many plants have been called for as can be furnished in the amount asked for. Under the "right of subst.i.tution"

which the society reserves in the matter of its plant premiums, probably plant premium No. 16 will be subst.i.tuted for Nos. 17 and 18 if matters turn out as now appears, though the number of plants sent will be more than is offered under No. 16. As this everbearing strawberry, originated at the fruit-breeding farm, No. 1017, is a very prolific plant maker, a dozen plants, if the runners are allowed to grow, will make plants enough to set out a bed of them next year, large enough in all probability for family use.

In the matter of June-bearing strawberry No. 3, offered as premium, there is undoubtedly stock enough to fill all orders including those asked for for which money has been sent, and we are in hopes that orders for raspberry No. 4 can be filled in their entirety, though it may be necessary to return money which has been sent for additional plants.
