Dwarf Apple Trees.

DR. O.M. HUESTIS, MINNEAPOLIS.

I have here a sample of McIntosh Red grown on a standard tree--a beautiful apple and well colored. Here I have the same variety grown on one of my dwarf trees, not quite as well colored.

Now, the dwarf tree that bore these apples has been planted two years; this is the second year of its growth in my own ground at Mound, on Lake Minnetonka.

I have sixty dwarf trees, five of which have been in eight years, and they have borne six crops of apples. The last ones I got two years ago, and they were two years old when I got them. I planted five of these dwarf trees at the same time that I planted forty standards. The dwarfs have borne more fruit than the standards up to date. Of course, they have only been in eight years. The standards are Wealthy, d.u.c.h.ess, Northwestern Greening and one or two Hibernal and some crabs; the dwarf stock is the Doucin. It is not the Paradise stock, which is grown in England largely and some in France and Germany. My trees are a little higher than my head, and I keep them pruned in a certain way. One of my older trees the second year had ninety-six apples on it. It was a Yellow Transparent, and they came to maturity very well. Several of my trees are about four feet high. I had from twenty-five to fifty apples on them, and they all ripened nicely. The Red Astrachan and the Gravenstein and one Alexander had a few apples on them, and I notice that they are well loaded with fruit buds for another year, which will be the third year planted.

The care of these trees is probably a little more difficult than that of the standard tree, or, at least, I give them special care. I have attempted to bud into some of these, but in my experience they do not take the bud very well. I can take a bud from one of the dwarfs and put it on a standard, and it will grow all right, but I can't take a bud from a standard and put it on a dwarf as successfully. I judge it is because it isn't as rapid growing as the Hibernal, for instance, would be. I notice the Hibernal is the best to take a bud because it is a rapid growing tree and an excellent one on which to graft.

If I wanted to plant an orchard of forty or fifty acres I would plant standard trees and would put the dwarf between the rows, probably twelve feet apart. Mine are about ten feet apart, some of them a little more, but I have two rows eight feet apart each way, nine in each row, which forms a double hedge. I expect them to grow four feet high. I will prune them just as I wish to make a beautiful double hedge between two cottages.

In pruning those that have been in eight years I have tried to use the renewal system as we use it on grapes sometimes. I take out some of the older branches and fruit spurs that have borne two or three years. They must be thinned out. I counted twenty apples on a branch a foot long. I let them grow until they are large enough to stew and then take some off and use them, when apple sauce is appreciated. I thin them every year and get a nice lot of good fruit each year.

I have noticed for two years that I have about ninety-eight per cent. of perfect apples, not a blotch nor a worm. I spray them all, first the dormant spray and then just as the blossoms are falling, and then one other spraying in two weeks and another spray three weeks later.

Mr. Ludlow: Do you mulch the ground?

Dr. Huestis: Well, I dig up the ground a little in the spring. The roots are very near the surface, not very penetrating, and I cultivate around the roots, but I am careful not to cut them. Every fall I put a good mulch of leaves and hay around them. I have been a little fearful they would winter-kill. I wouldn't lose one of them for ten dollars, and I think it well to mulch them, leaving a little s.p.a.ce at the base.

Mr. Andrews: Are the roots exposed in some cases?

Dr. Huestis: Yes, I noticed on two of the older trees, those that have been in eight years and have borne six crops, you can see the roots on one side, the top is exposed a little, and I think it would be well to put a little dirt on those another year. The stock of these dwarf trees is slow growing with a rapid growing top, and that is what dwarfs them.

I have transplanted one tree three times, which would make four plantings in eight years, and that tree bore almost as much fruit last year as any of them. In another case once transplanted I think the tree is better than the others that were left.

[Ill.u.s.tration: Dwarf Yellow Transparent, bearing 96 apples, third year from planting at Dr. Huestis'.]

As I said before, if I was planting an orchard I would put dwarf trees between, and by the time they had borne three or four crops, and you were expecting a crop of fruit from the standard trees--about seven years from the time you put them in--I would put the dwarf trees as fillers, costing about forty cents apiece, and by the time they are bearing nicely your friends would have seen those, and I believe would want them at the time you want to take them out. I believe I could sell any of mine for three or four dollars apiece. I think that would be one way of disposing of them after you wanted to take them out of the standard orchard on account of room. That is just a thought of mine.

When I got my first ones eight years ago I gave one to a man who lives in North Minneapolis, at 1824 Bryant Avenue North. Any one can see it who lives up in that section. The first year he had twenty-nine apples, and it has borne each year since. The one which I have transplanted and which bore last year is a Bismarck. It is a little better apple, in my mind, than the d.u.c.h.ess. It is a good deal like the d.u.c.h.ess but is a better keeper and has a better flavor than the d.u.c.h.ess.

[Ill.u.s.tration: Dwarf Bismarck, fourth year, at Dr. Huestis']

I would like to read a quotation to show that the dwarf tree is not a late thing. Recommending dwarf trees for gardens, "Corbett's English Garden," published in 1829, says: "I do hope if any gentleman makes a garden he will never suffer it to be disfigured by the folly of a standard tree, which the more vigorous its growth the more mischievous its growth to the garden."

Marshall says, "The fewer standard trees in the garden the better." Also that the dwarfs are less trouble to keep in order and are generally more productive, and that "placed eight or nine feet distant, pruned and kept in easy manner, they make a fine appearance and produce good fruit."

W.C. Drury, highly regarded as a modern English authority, writing in 1900 says: "For the private garden or for market purposes the dwarf, or bush, apple tree is one of the best and most profitable forms that can be planted." He also says: "The bush is one of the best forms of all, as it is of a pleasing shape and as a rule bears good and regular crops."

Mr. Clausen: Don't you have trouble with the mice?

Dr. Huestis: No, sir, have never seen any.

Mr. Clausen: I had an experience a few years ago. My neighbor made a mistake; he was hauling straw around his apple trees, and he happened to take one row of mine. We had no fence between us--and he laid the straw around the trees. I found when I came to examine these trees in the spring they were all girdled around the bottom. I am afraid to mulch.

Dr. Huestis: I never have taken any chances. Ever troubled with the mice at your place, Mr. Weld?

Mr. Weld: A little.

Dr. Huestis: I have never had any trouble with the mice. I always put on a lot of old screen that I take from the cottages that is worn out and put a wire around it so the mice can't get through it. We must protect from mice and rabbits.

Mr. Kellogg: How soon do your dwarf trees pay for themselves?

Dr. Huestis: I don't know. I reckon these four have paid about twelve per cent. on fifteen or twenty dollars this year, and they have right along. They have paid me better so far during the eight years than the standards. That might not apply in eight more years, but for a city lot, a man who has fifty square feet, how many apple trees could he put in that seventeen feet apart? Nine standard trees. In that same plot of fifty feet square he could put in sixty-four dwarfs, and it would be a nice little orchard. I think it is more adapted to the city man. The ordinary farmer would neglect them, and I should hate to see a farmer get them, but I would like to do anything for the man living in the city with only a small plat of land--my vocation being in the city, my avocation being in the country.

Mr. Kellogg: Are those honest representations of the different apples from the dwarf and the standard?

Dr. Heustis: I don't know. Those are a fair sample of those I found in a box on exhibit and are Red McIntosh. They are better colored than mine, most of them are like this (indicating). I find the Yellow Transparent that I have budded on the standard better on the dwarf than on the standard.

Mr. Kellogg: Does it blight any?

Dr. Huestis: No blight; there hasn't ever been a blight. I think that is one reason why I feel I could recommend them quite conscientiously.

Other trees have blighted when the conditions were favorable.

TWENTY-FIVE BY SEVENTY FOOT PLOT WILL PRODUCE ENOUGH VEGETABLES FOR A SMALL FAMILY.--Even the smallest back yard may be made to yield a supply of fresh vegetables for the family table at but slight expense if two or three crops are successively grown to keep the area occupied all the time, according to the garden specialists of the department. People who would discharge a clerk if he did not work the year round will often cultivate a garden at no little trouble and expense and then allow the soil to lie idle from the time the first crop matures until the end of the season. Where a two or three crop system is used in connection with vegetables adapted to small areas, a s.p.a.ce no larger than twenty-five by seventy feet will produce enough fresh vegetables for a small family.

Corn, melons, cuc.u.mbers, and potatoes and other crops which require a large area should not be grown in a garden of this size. Half an acre properly cultivated with a careful crop rotation may easily produce $100 worth of various garden crops in a year.
