CHAPTER III.
MANAGEMENT OF THE CROP.
SOIL.
Almost any soil will do for the cauliflower, providing it is moist and fertile. The requirements of this vegetable as to soil are practically the same as those for the cabbage, except, that as the cauliflower will stand less drouth, it should generally have a heavier and richer soil, and rather more room. A soil which produces cabbages with large and rather soft heads is likely to be good for cauliflowers; that is, it contains more vegetable matter than the right amount for producing hard heads of cabbage. Muck will answer for cauliflowers if it is not too wet or too dry; it should like any other soil be treated to a good coat of barn-yard manure—horse manure being preferable on such land, as it promotes fermentation. Small quantities of lime may also be applied for the same reason.
The best soil is generally a strong sandy loam. Light sand or gravel is the poorest; and unless made very rich and artificially watered, it is useless to attempt to grow cauliflowers on such a soil in ordinary seasons. Heavy clay is less suitable for cauliflower than for cabbage, chiefly because on such a soil the plants are apt to be small and late. In a warm climate a heavier soil is required than in a cool one. The ground should, if possible, be fresh sod-land (preferably pasture) or at most one year removed from the sod. It is unsafe to plant cauliflowers after cauliflowers, or any other plant of the cabbage tribe, though it is sometimes successfully done. Newly cleared land, or land fresh from the sod, is even more desirable for cauliflowers than for cabbages. On new land the crop is not only less subject to disease and the attacks of insects, but its growth is likely to be more satisfactory, even without manure, or with only a moderate amount, than it is on old land, however well manured.
FERTILIZERS.
The cauliflower is a gross feeder, and land intended for this crop can hardly be made too rich. Barn-yard manure is usually employed, and there is nothing better for general use. Commercial fertilizers—potash, soda and phosphates—are also good, especially to promote heading. The wild plant from which the cauliflower is derived being a native of the sea-shore, common salt seems particularly adapted to it. Kelp, or sea-weed, is used with advantage where it can be obtained.
If barn-yard manure is not too coarse, plowing it under in moderate amount will, in addition to its fertilizing effect, help to keep the land moist. Where the cabbage maggot is troublesome the use of fresh stable manure is thought to promote the attack of that insect, and therefore only well rotted manure is recommended. Of course a larger amount of manure may be safely applied if it is well rotted than if it is coarse and strawy. Liquid manure is used by many growers, being applied a few weeks before planting, and from time to time during the season. Water-closet contents, diluted or composted, and applied either in the liquid or powdered form, is one of the best of fertilizers for the cauliflower, but it should not be used too freely, or too late in the season. All coarse or concentrated fertilizers should be applied at least two weeks before the time for transplanting, and such as are applied on the surface should be well mixed with the soil.
