_Peaches_ and _nectarines_ are the most valuable of our wall fruit trees. They should be grown in tolerably rich soil, but which has been enriched with decayed leaves rather than animal manure; as, when they are manured with dung, they are very apt to produce what are called water shoots or gourmands, that is, strong vigorous shoots without any blossom buds. Peach trees are generally kept in the nursery till they are three or four years old, and they should be removed about the latter end of October, or the beginning of November. They are best trained in the fan manner, that is, with the branches spread out regularly against the wall in the shape of a fan; and, as they always bear their fruit on shoots of a year old, those shoots must be left on in pruning, and the old wood cut out. The pruning should be performed either in November or February; but the trees should never be cut during a severe frost. When the fruit has stoned it is thinned out, and never more than two should be left growing together. Peaches and nectarines are generally grafted close to the ground, so as to make dwarf trees, and they are considered best planted about twenty feet apart, with some kind of plum or cherry, grafted standard high, placed between them. _Apricots_ are trained somewhat horizontally, and they bear not only on the shoots of the last year, but on close spurs formed by the two years' old wood. Apricot trees are very apt to have large limbs die off without any apparent cause; but this may be prevented by covering all the principal limbs in October with hay-bands, and letting them remain on till all danger is over from frost. Apricot trees should be five and twenty feet apart on the wall, as they spread rapidly, and do not bear cutting in. The fruit should be thinned in May, or the beginning of June. _Plum trees_ will bear a little manure being laid on the surface in autumn, and slightly forked in in spring. They are trained horizontally, and they bear on what are called spurs; that is, short rugged-looking little branches, jutting out from shoots two or three years old, and which will continue fruitful for several years. Plum trees, in consequence, require very little pruning; and, in fact, as they are apt to gum when they are wounded, they should be very seldom touched with a knife. _Cherry trees_ resemble plum trees in their culture, and, when grown against a wall, most of the kinds are trained horizontally, and their branches kept six or eight inches apart. The morello cherry is, however, an exception to this rule, as it requires pruning and training, like the peach.
