The Climbing French Bean is especially useful for producing crops under glass in spring and autumn, and the plants do well when grown in narrow borders with the vines trained close to the roof-glass by means of wire or string to which the growth readily clings. The general treatment may be much the same as that recommended for the Dwarf varieties, special care being taken with regard to watering and the giving of air. During the autumn months atmospheric moisture must be cautiously regulated or much of the foliage will damp off, while in spring a humid atmosphere should be maintained and systematic watering practised. Cucumber, Melon, and Tomato beds from which the crops have been cleared may often be used to advantage for raising a crop of Climbing Beans, and generally these beds are in excellent condition for the plants without the addition of manure.
==Haricot Bean==
Although in France the term =Haricot= is given to all types of Beans, except those of the English Broad Bean, in this country the word =Haricot= is generally applied only to the dried seeds of certain Dwarf and Climbing Beans, notably those which are white. Almost any variety, however, may be used as =Haricots=, but the most popular are those which produce self-coloured seeds, such as white, green, and the various shades of brown. Seed should be sown early in May and the plants treated as advised for French Beans. The pods should not be removed from the plants until the seeds are thoroughly ripe. If ripening cannot be completed in the open, pull up the plants and hang them in a shed until the seeds are quite dry.
==Runner Bean==
==Phaseolus multiflorus==
Runner beans need generous cultivation and will amply repay for the most liberal treatment. The main point to be borne in mind is that the plant possesses the most extensive root-system of any garden vegetable. Deep digging and liberal manuring are therefore essential where the production of the finest crops is aimed at. If possible the whole of the ground to be allotted to Runners should be deeply tilled and well manured in autumn or winter. But where this is inconvenient, trenching must be carried out in March or early April. Remove the soil to a depth of two feet, and the trench may be two feet wide for a double row of Beans. Thoroughly break up the subsoil, half-fill the trench with well-rotted manure, and restore the surface soil to within a few inches of the level.
