Celeriac is a form of celery, or at least is a very near relation to the real celery, and requires about the same soil preparation and the same conditions and tillage. Celeriac is frequently sown where it is to stand, but as the seed is as slow to sprout as celery, this is not really a wise plan. Sown in a seed-bed and transplanted, the crop gives far better results. In celeriac it is not the stalk but the enlarged, tuber-like root which is eaten, and the plant requires no blanching. It may be eaten raw in a salad, or cooked, as you like. Good roots should be from three to four inches in diameter and they may be kept through winter by packing in sand or moss as many other vegetables may be kept. Celeriac is sown in the same quantities as celery seed, the rows being only far enough apart to allow of cultivation, and the plants from six to eight inches apart in the rows. Being of a dwarf nature the close planting does not cause the plant to over-shade itself. FOOTNOTES: [7] NOTE.—Fullerton says that the narrow-leaved, deeply serrated plant called endive in this country, in France is the chicory or succory known to all Americans as a roadside weed with beautiful blue flowers like a very open aster. CHAPTER XIX. PULSE CROPS. Peas and beans are the pulse plants, and although they are cousins they are widely different in their requirements. In this respect peas and beans resemble children, who though in the same family, do not always thrive under the same conditions or do best with the same treatment. Both these crops are leguminous, and, therefore, capable of storing the nitrogen from the air in their roots, and thus enriching the soil where they grow, yet it is often necessary to apply nitrogen to secure a quick start for early crops. This is especially true where the soil has not before been used to grow leguminous crops. The more we study plants the more we learn about children and the more likely are we to recognize the close relation between all forms of life. PEAS.
