Sea kale

Definition and stakes

Ida D. Bennett,  The Busy Woman's Garden Book

“ Sea Kale, less well known than the annual kale, is a hardy perennial that is cultivated somewhat like asparagus, the seed being sown in the spring in rows three to four feet apart. The seedlings give a crop the third year but quicker results come from planting root cuttings or offsets. The Sea Kale has a very long tap-root and should be grown in rich mellow soil that has been ploughed or dug very deep. As soon as shoots show above the ground blanch with boards, earth, sand or anything that will exclude light until ready for use. ”

“ Sea Kale is the easiest thing in the world to force; the only point of importance is to have strong roots to begin with. Any place such as Mushroom-houses, cellars, pits, or old sheds, where it is possible to maintain a temperature of 45° to 55°, may be utilised for the purpose. Put the plants thickly into pots or boxes, or plant them in a bed, and it is essential to exclude light to insure blanching. By these simple means a regular supply may be obtained until the permanent beds in the open ground come into use. ”

“ Sea-kale is planted in beds in the same manner as asparagus, when the plants are a year old. The first year the plants will require little care, except cutting down their flower stems whenever they appear; but the second year, each plant must be covered with river-sand, and then have a sea-kale pot turned over it, on which must be heaped stable dung fifteen or twenty inches high, in order that the heat may make the young shoots grow rapidly, and thus make them tender and succulent. ”
