On my Pommier de Paradis stock, Apples may be planted eighteen inches apart each way, and when they begin to touch each other may have each alternate tree removed, leaving the plantation at three feet apart each way. At this distance they will do to stand many years. I had nearly 1,000 sorts in the season of 1868 in fruit, many of them bearing six to twelve Apples, the trees being twelve inches by eighteen inches apart, and most of them only one foot to one and a half in height. The great thing with this stock is that all the large Apples, which are generally strong growers and slow bearers, bear abundantly in two or three years, and produce fine handsome fruit, generally better flavored than when from the Crab or Doucin stock. The management of these trees is very easy and simple - that is, if any of them should have an inclination to grow too luxuriant, merely lift them out of the ground, tread down the place firmly, and then place the tree on the part so hardened, covering its roots with a few inches of the surrounding soil, thus raising the tree on a little mound, which will prevent the roots striking too deep into the cold crude soil; and as a consequence, the wood will be well ripened and a fruitful tree be formed.
Little pruning is necessary; a few over-luxuriant shoots pinched back slightly once in summer, and a neat and thin regulation of its branches in autumn and winter, is all that is required. Avoid too much summer pinching and pruning, otherwise your trees will become ugly little stunted scrubs, with their skins so tight that the life is strangled in its ascent, and deformed abortions will be all you will have. Be generous to your trees; do not overpinch, overprune or overload them, and they will repay you with interest.-Scott's Orchardist.
