Cauliflower
This plant requires a very rich, moist soil. Land that will produce only a fair crop of cabbage is unfit for cauliflower. If the land is very rich and well fertilized it may be reasonably expected that the returns from the crop of cauliflower will more than repay the cost of putting the land in good condition.
Seed.—No more important element enters into the success of the cauliflower crop than the quality of the seed and to the seed alone is often due the difference between success and failure, profit and loss. The best seed that can be secured is the cheapest at any reasonable price, and it should always be obtained from a well-known, reputable seedsman.
Seed-bed.—This should be carefully prepared. The soil should be enriched with a liberal application of commercial fertilizer, or thoroughly decomposed stable manure. After the fertilizer is applied it should be thoroughly worked in to a depth of three or four inches. From a few days to two weeks should elapse before the seed is sown for there is great danger in planting seed too soon after applying commercial fertilizer as the seed is likely to be destroyed by the action of the mineral substance unless it has been dissolved and thoroughly incorporated with the soil. The time between the application of the fertilizer and the sowing of the seed will depend upon the amount of rainfall and it is often better to wet down the seed-bed each day for four or five days before planting and not to depend upon the uncertain rainfall. The rows should be about three inches apart. In six or seven days the young plants should begin to appear and the ground between the drills should be cultivated. Do not allow the soil to dry out as the cauliflower plant from seed to head should never be checked. Neither should the bed be kept too wet, else there is danger of “damping off.” The bed should be carefully watched and if the disease does break out it may be checked by removing the diseased plants, working the soil, scattering dry sand and sulphur along the rows and withholding water until the surface soil becomes dry. It might be pointed out here that about six months must be allowed from the sowing of the seed until the crop matures.
Transplanting.—The plants should not be allowed to remain long in the seed rows. If left too long they will soon crowd and become weak and spindling. When they have reached the height of one inch, they should be pricked off and set in another portion of the bed. They may be set in rows four inches apart with the plants one and a half to two inches apart in the rows. Here they should remain until ready for the field. If care has been exercised all the way through, the plants will be short, stocky and vigorous. By the time they are four or five inches high or when the leaves have lapped they are ready for the field. It is not best to let them get too large, because there is often a delay of a few days in order to obtain good climatic conditions for setting out. If left too long in the seed bed, greater care must be exercised in transplanting, else the plants may suffer a severe check and will button or break irregularly instead of forming smooth well shaped heads.
Soils and Preparation.—Work should be started on the ground at least a month before the plants are set out. The cauliflower is a deep rooted plant, consequently the soil should be prepared deeply. It is not advisable to turn under the good surface soil and to obviate this ground may be plowed shallow and then stirred and opened with a bull-tongue to a depth of seven or eight inches. After this the surface should be cultivated to a depth of two or three inches. Give thorough preparation by frequent cultivation before the fertilizer is applied, preparatory to setting out the plants.
Setting Out.—It is best that the plants be set out either just before or immediately after a rain, but if this can not be done they should be set out late in the evening and watered, giving each plant about a quart of water. A cloudy day is much preferable to a clear one and if the day on which the plants are set out is followed by cloudy weather, so much the better. The ground should be leveled or smoothed over, for which purpose a roller or float may be used. After this the ground may be marked off. Two markers should be constructed, one with the teeth three feet apart, the other with the teeth two feet apart. These may be made of wood after the pattern of an ordinary garden rake. In place of a marker a line may be used or the ground may be checked off with a light hand plow. Only a limited number of plants should be removed from the seed-bed at one time. The leaves should be cut back about one-half or one-third, using for the purpose a large pair of shears. Sprinkle the plants with water as soon as removed from the bed, place in a shallow box or basket and keep them shaded from the sun.
Cultivation and Care.—The field should be frequently cultivated and the ground should be scarified at least every week and after every rainfall. The best tool for cultivating is an ordinary cultivator and the ground should not be worked to a greater depth than two and one-half or three inches. This will preserve a surface mulch of dry earth and prevent loss of moisture by evaporation. As soon as the heads commence to form the leaves should be drawn together at the top and loosely tied near their tips with a piece of cord or twine. Rafia makes a good substitute for twine and is preferable because there is less danger of cutting the leaves. The practice of breaking down the leaves over the head has been tried, but found not quite so satisfactory. If the heads are left uncovered they become yellow through the action of the sun and rain but when the leaves are drawn together and tied, they bleach out pure white, and curd-like.
Gathering.—Cauliflower may be cut before it is mature, but the flavor is not so well developed as it is when the heads are full grown. For winter shipment heads from four to six inches in diameter are of a desirable size and the market will take them fully as well or better than large ones. The field should be picked over at least every two or three days during the season, though heads will remain in good condition for nearly a week if the weather be cold. Examine the head by separating the leaves on the side. As soon as the head is well rounded up in the center and developed so as to force the leaves outward, and assumes a grained appearance, it will be found to be fully matured. The heads should be cut, preferably, when dry. If moist they are likely to decay in transit. The best time of day is the afternoon if they are intended for long distance shipment. About an inch of stem should be left on the head and three rows of leaves. After cutting, the heads should be carefully placed in a wagon and carried to the packing house or on dry pleasant days packing may be done in the field.
Packing.—The package recommended for general use is the ordinary lettuce basket. Before packing, the leaves should be cut back to stubs. Each head should be carefully wrapped in a large sheet of white glazed paper. The baskets should be packed snug and tight without bruising the heads, and only those of uniform size should be placed in each basket. Never place different sizes in the same package and always discard inferior or injured heads; the compost heap is the place for them.—(F. B. 255; Fla. E. S. 59; Tex. E. S. 57; Cornell U. E. S. 292.)
