As asparagus in its wild state is usually found growing in light and
sandy soils along or near the seashore, it has long been supposed that
it could not be cultivated in other localities and soils. While it is
true that asparagus succeeds
best in a sandy, rich, and friable loam,
naturally underdrained and yet not too dry, there is not another
vegetable which accommodates itself more readily to as varying soils and
conditions. There is hardly a State in the United States in which at
present asparagus is not grown more or less extensively and profitably,
and the most famous asparagus districts of France and Germany are
situated at great distances from the seashore.
The question of what soil to use is, as a rule, already settled; we have
to use the soil we have. Any good garden soil is suitable for asparagus,
and if it is not in the most favorable condition, under existing
circumstances, it can easily be made so. The soil should be free from
roots, stones, or any material that will not readily disintegrate, or
that will interfere with the growth of the spears, and with the knife in
cutting. Fruit or other trees, or high shrubs, must not be allowed in
the asparagus bed, because of the shade they throw over the beds, and
because their roots make heavy drafts upon the soil. Nor should high
trees, hedges, hills, or buildings be so near as to shade the beds,
because all the sunshine obtainable is needed to bring the spears
quickly to the surface. Whenever practicable the asparagus bed should be
protected from cold winds, and so slope that the full benefit of the
sunshine will be obtained during the whole day. Brinckmeier, in his
"Braunschweiger Spargelbuch," gives the following three rules for
guidance in selecting a location for asparagus beds:
"1. One should choose, in reference to ground characteristics, open,
free-lying land, protected to the north and east [which, for American
conditions, should be north and west], of gradual slope, free from trees
or shrubbery.
"2. The field should be exposed to the rays of the sun all day long;
therefore, a southern exposure is desirable, or, if that is not
obtainable, a southwesterly or southeasterly slope, because either east,
west, or north exposure will cause shade during a greater or less
portion of the day.
"3. Standing, stagnant ground water, which cannot be drawn off by
drainage, is to be avoided, the requirements of the plants indicating a
somewhat damp subsoil, but not too high ground water."
For commercial purposes on a large scale, and when the trucker has the
choice of location, a well-drained, light, deep, sandy loam, with a
light clay subsoil, is to be preferred to any other. Heavy clay soil, or
land with a hard-pan subsoil, or, in fact, any soil that is cold and
wet, is totally unfit for profitable asparagus growing, unless it is
thoroughly underdrained and made lighter by a plentiful addition of sand
and muck.
Freedom from weeds is very desirable, even more so than great
fertility, for the latter can be produced by heavy manuring, which the
future cultivation will require; and to the end that weeds may be few,
it is well that for a year or two previous to planting the land should
have been occupied by some hoed crop, such as potatoes, beets, cabbage,
etc. Land on which corn has been growing for two or three years is in
excellent condition for an asparagus field, provided it has been heavily
manured one year previous to the planting of the roots.
