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.
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 space 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.

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.
