BROAD AND LONG-PODDED (Faba vulgaris). Cultivation: As early as possible in the autumn, deeply trench a piece of ground, and work in a heavy dressing of manure, leaving the surface of the soil in ridges, to become well aërated by winter frosts. Where desired, a piece of ground on a warm, protected border, can also be deeply dug in November, and a few rows of Mazagans sown to stand the winter. When up, draw a ridge of soil on either side the rows, and in frosty weather strew a few handfuls of bracken, or other light, dry litter, over them. Not much is, however, gained by this winter sowing. Early in January, level the ridges with a fork, working the whole of the surface soil over, and towards the end of the month, make the first sowing, choosing Mazagan and other early varieties. Mark out two rows, 9in. asunder, leave a space of 30in., then another two rows, and so on throughout the piece sown. If preferred, they may be sown in single rows at intervals of 1½ft. The drills should be about 3in. deep, and the seed from 7in. to 9in. apart in the rows. Where the double-row system is adopted, arrange the seed for the plants to come alternately. In March, get in the main sowing of the Broad and later Long-podded kinds, in the manner already described; another sowing for late use may be made in April. When the plants are about 6in. high, earth up as recommended for those sown in the autumn. As soon as a good crop is set, pinch out the tops of the plants, to assist the maturation of the Beans, and prevent the attacks of the fly. Figs. 209, 210, and 211 are excellent representations of the flowering plant, pods, and seed of the Broad Bean.
Sorts. For early use: Early Mazagan, Long-pod, Marshall's Early Prolific, and Seville Long-pod. For late use: Carter's Mammoth Long-pod, and Broad Windsor (white variety). These are all distinct and good varieties.
FIG. 212. FRUITING PLANT OF DWARF OR FRENCH BEAN (PHASEOLUS VULGARIS).
DWARF OR FRENCH KIDNEY BEANS (Phaseolus vulgaris). Cultivation: This class (see Fig. 212) also requires a rich and deeply trenched rather light soil. A very important point is to get the ground into a good condition, by frequently forking it over; and, as the seeds are not sown till the beginning of May, there is plenty of time for the work. The finer the soil is, and the more it is aërated, the better will it suit the crop. From the beginning of May till the end of June, at intervals, draw out drills about 2ft. apart, and 3in. deep, and in these place the Beans tolerably thick, as generally they are not all certain to grow. As soon as up, carefully thin them, and slightly earth up to prevent the wind blowing them about. They should not, however, be earthed higher than the seed leaves, or they will probably rot off in wet weather. Keep free from weeds, and maintain a sharp look out for slugs. In dry weather, water occasionally, giving good drenchings, and not mere sprinklings, which do more harm than good. A good mulching of half-rotted manure is very beneficial, as it prevents evaporation to a great extent, besides affording some amount of nourishment to the plants. Great care must be taken to pick off the Beans as soon as large enough for use, or they will exhaust the plants. Where seeds are needed, a number of plants should be left for the purpose, and these should be some of the best, to prevent deterioration, or loss of the true variety.
Forcing. French Beans require more heat than can be obtained in either a frame or an ordinary greenhouse; and, although easy enough to grow in a structure suited to their requirements, yet, if such does not exist, they are almost sure to fail. A good heat, from 60deg. to 70deg., with abundance of moisture, is necessary for successful results. Plenty of light is also most essential. A position such as that of a cucumber house is generally a suitable one; but the plants must not be placed under the cucumbers. Successional sowings in pots or boxes must be made, from the end of August till March, to keep up a supply. For soil, use good maiden loam, with a little well-rotted manure added. Use 8in. pots, sowing five or six beans in each. The first sowing should be placed in a frame and kept well watered, bringing into heat in October; but the subsequent sowings should be placed directly in the house. Keep the soil moist, and the plants free from aphides and other insect pests, and give air at every favourable opportunity. The plants should be as near the light as possible, and kept from falling about by tying or placing small pieces of Birch wood round them. In dull weather, it will be found that the blooms will not set so freely as when the sun shines brightly; therefore, every care should be taken to secure both heat and ventilation when sunshine prevails. When the pots get full of roots, and the plants are bearing fruit freely, a little liquid manure is of great assistance; at no time must the plants get dry enough to flag. Allow plenty of room for the full development of foliage, and maintain a minimum temperature of 60deg., with plenty of moisture.
Sorts. These are very numerous, among the best being Black Negro, Canadian Wonder, Canterbury, Fulmer's Forcing, Golden Dun, Newington Wonder, Osborn's Early Forcing, Sion House, and Sir Joseph Paxton.
RUNNERS OR CLIMBING KIDNEY BEANS (Phaseolus multiflorus). Cultivation: Being tall growers, these need a greater space than the Dwarf French varieties, and they also require support. Rich soil is indispensable for them, and liberal supplies of water on light soils and in dry weather. A good overhead syringing from time to time is also advantageous. Trench and heavily manure a piece of ground in autumn, leaving it in ridges for the winter. In March, level the ridges down, and well work the ground, to render it friable and in good condition. The plants being extremely tender, it is not safe to sow before the end of April or the first week in May. It is preferable to sow in rows, which should be from 6ft. to 12ft. apart, and crop the ground between with other vegetables. Earth up and stake them as soon as ready, to prevent injury from rough wind. A good plan, which may be adopted to obtain early produce, is to raise the seeds in boxes in a cold frame, getting them ready for planting out in the middle of May. Plant at the same distances, and treat afterwards as recommended for those sown out of doors.
If preferred, they can be grown on the ground without stakes. Under this treatment, they must have their tops pinched off when about 18in. high, continuing this pinching from time to time as necessary. If this plan is adopted, the rows need only be 3ft. apart, the ground not being otherwise cropped. In dry seasons and on light soils, there is an advantage attached to this method, namely, that those on sticks are liable to injury from drought, while the foliage of those pinched back keeps the soil moist underneath.
