Phaseolus vulgaris
Among summer vegetables Dwarf French Beans are deservedly in high
favour, and are everywhere sown at the earliest moment consistent with
reasonable expectations of their safety. This early sowing is altogether
laudable, for although it occasionally entails the loss of a plantation,
the
aggregate result is advantageous, and a very little protection
suffices to carry the early plant through the late spring frosts. But
those who supply our tables with green delicacies do not all recognise
the importance of late sowings of Dwarf Beans. Here, again, a risk must
be incurred, but the cost is trifling, and when the summer is prolonged
to October the late-sown Beans are highly prized. Even if they produce
plentifully through September there is a great point gained, but that
cannot be secured from the earliest sowings; it is impossible. After
July it is useless to sow Beans, but where the demand is constant, two
or three sowings may be made in this month, choosing the most sheltered
nooks that can be found for them. For late sowings the earliest sorts
should have preference.
Dwarf Beans for main crops require a good though somewhat light soil;
but any fairly productive loam will answer the purpose, and the crop
will yield an ample return for such reasonable digging and dressing as a
careful cultivator will not fail to bestow. At the same time, it is a
matter of some practical importance that the poorest land ever put under
tillage will, in an average season, yield serviceable crops of these
legumes, and on a rich soil of some depth the Dwarf Bean will endure
summer drought better than any other crop in the Kitchen Garden.
Earliness of production is of the highest importance up to a certain
point; but an early crop being provided for, abundance of production
next claims consideration, the heaviest bearers being of course best
adapted for main-crop sowing. As regards the sowing and general culture,
it is too often true that Dwarf Beans are crowded injuriously, even in
gardens that are usually well managed. Nothing is gained by crowding. On
the contrary, loss always ensues when the individual plant, through
deficiency of space, is hindered in its full development.
For early crops which are eventually to come to maturity in the open
ground, the first sowings may be made in the month of April, either in
boxes in a gentle heat, or better still in a frame on a sunny border
without artificial heat. In districts where frost frequently prevails in
May, and on heavy soils where early sowings outdoors are impracticable
in a wet spring, the forwarding of plants under glass is very desirable,
but the actual date for sowing must depend on local conditions. The
tender growth that is produced by a forcing process is not well adapted
for planting out in May; but a plant produced slowly, with plenty of
light and air, will be stout and strong, and if put out with care as
soon as mild weather occurs in May, will make good progress and yield an
early crop. The seed for this purpose should be sown in rather light
turfy soil, as the plants may then be lifted without injury to their
fleshy roots. Careful treatment will be desirable for some time after
they are planted, such as protection from sun and frost, and watering,
if necessary, although the less watering the better, provided the plants
can hold their ground. The plot to which these early sowings are to be
transplanted should be light and rich, and lying towards the sun; open
the lines with the spade or hoe in preference to using the dibber, and
as fast as the roots are dropped into their places with their balls of
earth unbroken, carefully restore the fine soil from the surface. Rough
handling will seriously interfere with the ultimate result, but ordinary
care will insure abundant gatherings of first-class produce at a time
when there are but few in the market. On dry soils a small sowing may be
made about the second week of April on a sheltered south border. Sow in
double rows six inches apart, and allow a distance of two feet between
the double rows. When the seedlings appear give protection if necessary,
and in due course thin the plants to six inches apart in the rows.
Main crops are sown from the last week in April to the middle of June.
The distance for the rows may be from one and a half to two feet apart,
according to the vigour of the variety, the strongest growers requiring
fully two feet, and the distance between the plants may be eight to
twelve inches; therefore it is well to sow the seed two to three inches
apart, and thin out as soon as the rough leaves appear. The ground being
in fairly good condition, it will only be necessary to chop over the
surface, if at all lumpy, and with the hoe draw drills about two inches
deep, which is far better than dibbling, except on very light soil, when
dibbling about three inches deep is quite allowable. Generally speaking,
if the plot be kept clean, the Beans will take care of themselves; but
in droughty weather a heavy watering now and then will be visibly
beneficial, for although the plant bears drought well, it is like other
good things in requiring something to live upon. In exposed situations
and where storms are prevalent, it is an excellent practice to support
the plants with bushy twigs.
Late Crops.--To extend the outdoor supply sowings may be made early in
July. When the ground has become dry and hard, it is advisable to soak
the seed in water for five or six hours; the drills should also be
watered, and, if possible, the ground should be covered with rotten
dung, spent hops, or some other mulchy stuff to promote and sustain
vegetation.
The gathering of the crop should be a matter of discipline. Where it
is done carelessly, there will very soon be none to gather, for the
swelling of a few seeds in neglected pods will cause the plants to cease
bearing. Therefore all the Beans should be gathered when of a proper
size, whether they are wanted or not; this is the only way to insure a
long-continued supply of good quality both as to colour and tenderness.
Autumn, Winter and Spring Supplies.--By successional sowings under
glass a continuous supply of Beans may be obtained through autumn,
winter, and spring. The earliest sowings should be made at fortnightly
intervals, from mid-July to mid-September, in cold frames filled with
well-manured soil. Put in the seeds two inches deep and six inches
apart, in rows one foot apart. Water copiously during the hot months and
give protection when the nights become cold. After mid-September crops
of dwarf-growing varieties should be raised in heated pits, or in pots
placed in a warm temperature. In pits the beds should be one foot deep,
the drills one foot apart, and the plants six inches asunder in the
rows. When pots are used the ten-inch size will be found most
convenient. Only three-parts fill the pots with a good compost, and
insure perfect drainage. Place eight or nine beans one and a half inches
deep in each pot, eventually reducing the number of plants to five. As
the plants progress soil may be added to within an inch and a half of
the rims. Air-giving and watering will need careful management, for the
most robust growth possible is required, but there must be no chill, and
any excess of either moisture or dryness will be immediately injurious.
When a few pods are formed feed the plants with alternate applications
of soot water and liquid manure, commencing with highly diluted doses.
Thoroughly syringe the plants twice daily to combat Red Spider. At night
a temperature of from 55 deg. to 60 deg. must be maintained. In mid-February
sowings may be made in frames in which six inches of fertile soil has
been placed over a good layer of litter or leaves. From these sowings
heavy crops may be secured in spring and early summer before the outdoor
supplies are ready.
Flageolets is the name given to the seeds of certain types of Dwarf
and Climbing Beans when used in a state intermediate between the green
pods (Haricots verts) and the fully ripe seeds (Haricots secs), and
they are strongly to be recommended for culinary purposes. The use of
Bean seeds as Flageolets, although so little known in this country, is
very largely practised abroad, and in the vegetable markets of many
French towns the shelling of the beans from the semi-ripe pods by women,
in readiness for cooking in the manner of green peas, is a very familiar
sight. The seeds of almost all varieties are suitable for use in this
way, irrespective of colour, as this is not developed as would be the
case if the seeds were quite ripe.
