Ordinarily climatic and soil adaptation are prime factors in successful horticulture--much more than in any other branch of agriculture. Each fruit has a restricted climatic range, and in most cases the number of soil types on which a given fruit can be made a commercial success is likewise limited. Thus, in general, apples and pears require heavier soils than peaches. Success in commercial apple growing requires even greater discrimination, since different varieties of apples demand different soil conditions. Thus Baldwins are grown the most successfully where a northern climate is modified by proximity to the Great Lakes. Rhode Island Greenings will succeed on soils too heavy for many other varieties. The York Imperial has not yet achieved a great commercial success save on one type of soil. Some varieties of apples are much more restricted in their adaptation than others. Thus, while the King is quite restricted, the Ben Davis has a fairly wide cultural adaptation. No one should plant an orchard until he has made a thorough study of his soil and climatic conditions and has received the highest possible expert assistance in choosing the varieties best adapted to his conditions. There is an increasing tendency to specialize in vegetable growing. The production of celery, onions, muskmelons, watermelons, cabbages, cauliflowers, tomatoes and sweet corn, to mention only some of the most striking examples, are becoming more and more localized. Even where vegetables and flowers are grown under glass, not only is each house devoted to a single species, but, notably in the case of roses, growers are restricting themselves more and more to a few varieties. This is due to the fact that it is impossible to give in one house, or even in one establishment, the special set of conditions required for the most economic development of each species or variety of plant, just as in the open air the natural conditions are best adapted to a limited number of horticultural products. So much being admitted, it follows that it is folly to attempt to grow plants under unfavorable climatic and soil conditions when competing in the same market with those possessing favorable ones. It is true, of course, that where one man fails another often succeeds, but this is no reason why a man should apply his talents under unfavorable circumstances. In fact, one of the important attributes of most successful men is their ability to recognize and apply their energies under conditions which will give them the most effective return for a given effort. There is no virtue in unnecessary toil. Progress in any enterprise, as progress in the human race, can be accomplished only in reducing the amount of labor required to produce a desired result.
