Spinacia oleracea
Spinach plays an important part in the economy of the dinner table.
There are unfortunate beings who cannot eat it, for they describe it as
bitter, sooty, and nauseous. Probably an equal number of persons
entertain a very high opinion as to
its value. The rest of mankind
proclaim it a wholesome, savoury, and acceptable vegetable. Spinach will
grow anywhere and anyhow; but some little management is needed to keep
up a constant supply of large, dark green leaves, that when properly
cooked will be rich in flavour as the result of good cultivation. To
produce first-class Spinach a well-tilled rich loam is needed, but a
capital sample may be grown on clay that has been some time in
cultivation.
Summer Spinach.--The early sowings of Round or Summer Spinach should
be in a sheltered situation, but not directly shaded. Sow in drills
twelve to fifteen inches apart, and one inch deep, beginning in January,
although the first sowing may fail, and continue to sow about every
fortnight until the middle of May. The earliest sowing should be on dry
ground, but the later sowings will do well on damp soil with a little
shade from the midday sun. It is important to thin the crop early, as it
should not be in the least drawn. This is the only essential point in
securing a fine growth, for if the plant cannot spread from the
beginning it will never become luxuriant, and will soon run up to seed.
Thin at first to six inches, and if large enough for use, send the
thinnings into the house. Before the leaves overlap thin finally to
twelve inches. Every plant will cover the space, and it will suffice to
take the largest leaves, two or three only from each plant, and thus a
basket may be filled in a few minutes with really fine Spinach.
As the heat of the summer increases, the crop will be inclined to bolt.
The starved plant will bolt first; the plant in rich moist soil, with
plenty of room to spread, will be more leisurely about it, and will give
time for the production of a succession crop to take its place. The
sowings from May to July should be small and numerous, and on rich moist
land, to be aided, if needful, with water. In many gardens there is a
sufficient variety of vegetables after the middle of June to render it
unnecessary to keep up the supplies of Spinach, and it is best to
dispense with it, if possible, during July and August.
Winter Spinach.--The sowing of Winter Spinach should commence in
July, and be continued until the end of September, subject to the
capabilities of the place. In gardens near towns, where the land is at
all heavy, it is generally useless to sow after August, as the autumnal
fogs are likely to destroy a plant that is only just out of the
seed-leaf. But in favoured localities, with a warm soil and a soft air,
seed may be sown up to the very end of the year with but little risk of
loss. The winter crops are sometimes sown broadcast, but drilling is to
be preferred, and the rows may be twelve to fifteen inches apart. Thin
at first to three inches, and afterwards to six inches, and leave them
at this distance, for Winter Spinach may be a little crowded with
advantage, because the weather and the black bot will now and then
remove a plant. Should ground vermin claim attention, the best way to
proceed will be to scratch shallow furrows very near the plants, taking
care not to injure them. This may be done with the hoe, but if time can
be spared it will be better to do it with a short pointed stick, having
at hand, as the work progresses, a vessel into which to throw the grubs
as they come to light when the earth is disturbed. Where small birds are
in sufficient numbers, they will observe the disturbance of the earth,
and diligently search for the grubs at hours when the cultivator is no
longer on the search himself.
The July sowings will be useful in the autumn and throughout the winter,
as the weather may determine; the later sowings will be useful in
spring. Plants may be drawn where they can be spared to make room for
the remainder, but leaves only should be taken when the plant is large
enough to supply them. When symptoms of bolting become visible in the
spring, cut the plants over at the collar, and at once prepare the
ground for another crop.
New Zealand Spinach (Tetragonia expansa).--Gardeners are only too
well acquainted with the difficulty of maintaining an unbroken supply of
true Spinach during the burning summer months. But the weather which
makes it almost impossible to produce a satisfactory crop of Spinacia
oleracea brings New Zealand Spinach to perfection. The latter is prized
by some persons because it lacks the peculiar bitterness of the former.
The plant is rather tender, and therefore to obtain an early supply the
seed must be raised in heat. It may be sown in pots or pans at the end
of March or beginning of April. Transfer the seedlings to small pots
immediately they are large enough, and gradually harden in preparation
for removal to the open ground towards the end of May. They should be
put into light soil in a sunny position, and be allowed three or four
feet apart each way. It is not unusual to grow them on a heap of
discarded potting soil, where they can ramble without restraint. The
growth is rapid, and there must be no stint of water in dry weather. In
five or six weeks the first lot of tender shoots will be ready for
pinching off. Those who do not care to incur trouble under glass may sow
in the open in the early part of May, and thin the plants to the
distance named.
Perpetual Spinach, or Spinach Beet (Beta Cicla).--A valuable plant
for producing a regular supply of leaves which make an excellent Spinach
at a period of the year when the ordinary Summer Spinach is past its
prime. Although it is a true Beet, the roots are worthless, and there
should be liberal treatment to insure an abundant growth of leaves. Seed
may be sown from March to the end of July or beginning of August, in
rows one foot apart. Thin the plants to a distance of six or eight
inches in the rows. When the leaves are ready for gathering, they must
be removed, whether wanted or not, to promote continuous growth.
Orache is frequently used as a substitute for Spinach where the
ordinary variety fails. Seed should be sown during the spring months,
and as the plant frequently attains a height of five feet allow a
distance of at least three feet in each direction for development. Red
Orache is useful for growing in ornamental borders, but it is not so
suitable for culinary purposes as the white variety. The leaves only are
eaten.
