The field and garden vegetables of America

Soil and Planting.—"A rich, sandy, alluvial soil, impregnated with salt, is naturally best adapted to the growth of Asparagus; and, in such soil, its cultivation is an easy matter. Soils of a different character must be made rich by the application of fertilizing material, and light and friable by trenching. Sand, in wet, heavy, clayey soil, is of permanent benefit.

"The market-gardeners near London are aware of this; for, highly as they manure their ground for crops generally, they procure sand, or sandy mud, from certain parts of the Thames, for Asparagus plantations, where the soil is too heavy.

"The ground should be thoroughly trenched to the depth of two and a half or three feet: and, in order to make it rich, a large quantity of manure should be incorporated, as well at the bottom as near the surface,—using either sandy mud; the scourings of ditches made into compost; rock-weed, or kelp, where they can be procured; decayed leaves, or leaf-mould; the remains of hot-beds, good peat, or almost any other manure not in too crude a state.

"Where the soil is not so deep, and the subsoil coarse and rather gravelly, the ground is not trenched so deep; the bottom of the trench being merely dug over. Above this, however, a large quantity of manure is applied; and by this, with good after-management,—chiefly consisting in making the soil fine and light for the shoots to push through,—excellent crops are produced.

"The ground should be divided into beds either three or five feet wide, with an alley or path of two feet in width between. The reason for having some of the beds so much narrower than the others is, that the narrow ones are sooner heated by the sun's rays, and consequently an earlier production is induced.

"The distance between the rows in the beds may be regulated as follows: When the beds are three feet wide, two rows should be transplanted along them: each row should be a foot from the edge of the bed, and they will consequently be a foot apart. In beds that are five feet wide, three rows should be transplanted, also lengthwise,—one along the middle, and one on each side, a foot from the edge of the bed. The distance from plant to plant in the rows should not be less than one foot; at this distance, good-sized heads will be produced: but, if very large heads are desired for exhibition or competition, the plants should be fifteen, or even eighteen, inches asunder.

"The transplanting may be performed either in April or May. The three-feet beds should be traced out to run east and west, or so as to present the side of the bed to the direct action of the sun's rays when they are most powerful. Asparagus, in beds so formed, pushes earlier in the season than it does in beds running north and south. For all except the earliest beds, the direction is immaterial; and they may run east and west, or north and south, as may be most convenient.

"In proceeding to transplant, the beds, and paths, or alleys, should be marked off at the required distance. A stout stake should be driven at each corner of the beds, and from these the distances for the rows should be measured. There are various ways of transplanting. Some stretch a line, and cut out a trench only deep enough to allow the roots to be laid out without doubling; and they are spread out like a fan perpendicularly against the side of the cut, the crown of the plant being kept two inches below the surface of the ground. Some dig out a trench, and form little hillocks of fine soil, over which the roots are spread, extending like the sticks of an umbrella. Others make a ridge, astride which they set the plants, spreading their roots on each side of the ridge; and, again, some take off a portion of the soil on the bed, and, after the surface has been raked smooth, the roots of the plants are spread out nearly at right angles on the level.

"The first method is the most expeditious, and is generally practised in setting extensive plantations: but, whatever plan be preferred, the crowns of the plants should all be on the same level; otherwise those that are too high would be liable to be injured by the knife in cutting."

During the summer, nothing will be necessary but to keep the plants clear of weeds; and, in doing this, the hoe should be dispensed with as much as possible, to avoid injuring the roots. In the autumn, when the tops have completely withered, they should be cut down nearly level with the surface of the ground, and burned. The beds should then be lightly dug over, and three or four inches of rich loam, intermixed with well-digested compost, and salt at the rate of two quarts to the square rod, should be applied; which will leave the crowns of the roots about five inches below the surface.
