For this mode of planting we shall suppose the gardens to be laid out like that in fig. 34. in page 71, as in no kitchen-garden whatever, whether large or small, would we introduce standard fruit trees among the kitchen crops; because, as we have already stated (§ 119.), the digging and trenching necessary for the perfection of the latter, prevent the roots of the trees from spreading near the surface of the ground; and being forced to seek their nourishment in the subsoil, they run to wood from excessive moisture, become cankered, and do not produce either abundant crops or well-flavoured fruit. In a small garden of the kind we are treating of, standard trees would shade the ground so much, that, independently of other consequences, they would render it altogether unfit for the culture of culinary vegetables. We therefore propose to have no standards, but only trees trained against the walls, or boundary fences, and on the trellis-work. On the latter, we propose to train gooseberries, currants, and raspberries, and one or two apples and pears; and on the walls, peaches, nectarines, grapes, figs, apricots, cherries, and plums.
