Spinach is a cool-weather crop that requires a light soil heavily manured with decayed stable manure for best results. The seeds should be planted in very early spring or in September, in rows fifteen inches apart, and the plants thinned to stand four inches apart. Nitrate of soda as recommended for kohlrabi is good for this crop. Spinach (New Zealand).—Although called spinach, this is an entirely different plant and belongs to another family. It luxuriates during hot weather and will supply the table plentifully with “greens” throughout the summer. Seeds should be planted during April or May in rows two feet apart, the plants later being thinned to one foot. When the plants attain a foot in height picking may begin, using the tender shoot-tips, or leaves, as required. The thinnings, of course, are also available for cooking. Squash.—Cultivate the same as cucumber. The bush varieties should be planted four feet apart each way, and the vining kinds from six to eight feet. There are several different types of squash. The summer kinds are represented by the _Pattypan_ and _Crookneck_ types, and the winter varieties by the _Hubbard_. They are subject to much the same insect pests and diseases as the cucumber and muskmelon. Sweet Potatoes are not very well adapted for Northern gardens, although they are grown to a considerable extent in parts of New Jersey. They succeed best in a rich, sandy soil. The “sets” are usually planted on slightly raised, broad ridges about four feet apart. They are spaced from twelve to eighteen inches apart along the ridges. The production of “sets” is usually effected by placing small potatoes in a hotbed and covering them with sand. This causes them to sprout, and when the shoots are six or eight inches in length they are pulled off with roots attached and planted as described. _Yellow Jersey_ is a good variety for Northern planting. Swiss Chard.—See under Chard. Tomato.—This plant adapts itself to a great variety of soils, and will succeed almost anywhere if it receives warmth and sunshine. It is seldom worth while for any one without greenhouse facilities, unless he wishes to have the experience, to raise tomatoes from seed. Young plants can be obtained at a low cost at planting-time from seedsmen who have every convenience for raising them cheaply. The distance apart between the plants when they are set out in the garden depends on the method of training adopted. The truck farmers and market gardeners seldom go to the trouble of staking their plants. They are simply set out in the field three or four feet apart each way and allowed to grow naturally. This results in the spoiling of some of the fruit through coming in contact with the soil. The home gardener can usually afford the time and trouble required to stake his tomatoes, and receives his reward in the shape of more fruit of better quality.
