Seakale.--The readiest way of propagating this useful vegetable is by
off-sets, but it may be raised from seed sown in March or April in
rows 1 ft. apart. Thin out the young plants to 6 in. in the rows, and
transplant in February or March into well-trenched, deep, rich soil in
rows 2 ft. apart and the plants 15 in. asunder. Keep the plants to one
crown, or shoot, and remove all flower-shoots as they appear. In
dry weather give a liberal quantity of liquid manure. Cropping may
commence after the roots have been planted two years.
