AGE OF TREES FOR PLANTING.--This depends so much upon the views of planters, that the nurseryman cannot always control the period at which he shall clear a block of trees. Peaches should always be removed at one year from the bud. Plums and dwarf pears will be ready to go off at two years from the bud or graft; so with apples and cherries. But many persons, purchasers and sellers, prefer larger trees, and they recommend that the trees should remain one, two, or even three years longer in the nursery. Others, a new school of planters, prefer to set out the maiden tree, in most of the species above named, except some very feebly growing varieties, that will scarcely have attained sufficient size to risk in the orchard. The nurseryman should beware of keeping his trees too long on his hands; they may become unprofitable stock, and are sure to require much more labor in the digging and handling. The purchaser is his own master, and his tastes and wishes must be consulted; if he wants large trees, by all means, let him be indulged; he will have to pay in proportion, he will have more wood for his money, more weight to carry, or more transportation to pay for, more labor in planting, and vastly increased risk of the life of his trees; but, let him be indulged with his five year old trees, while his neighbor, for a smaller sum invested, with less freight, less wood, less labor, and infinitely less risk, will plant his maiden trees, and five years hence will market more fruit. The risk of transplanting large or old trees from the nursery, may be greatly diminished, and their value will be vastly enhanced, by judicious root pruning in the nursery-row. This may be done by digging, on either side, on alternate years, and cutting off the straggling roots, and particularly those that run deeply; this will be followed by the production of a multitude of fibrous roots that put the tree into a good condition for transplanting. In the great nurseries of the West, there is a peculiar plow, which is used for root pruning the nursery rows.
