The cauliflower is one of the minor vegetables which is now attracting more than ordinary attention in this country, and being grown with remarkable success and profit in a few localities which have been found to be particularly adapted to it. With most of our gardeners, however, it is still considered a very uncertain and unprofitable crop. This is due not only to the peculiar requirements of the cauliflower as to soil and climate, but also to the want of familiarity on the part of most American gardeners with modern varieties and with methods of cultivation adapted to our climate. For a number of years, while engaged in market gardening and fruit growing in Western Michigan, the writer made a specialty of raising cauliflowers for the Grand Rapids and Chicago markets, planting from three to five acres a year. During this time most of the varieties offered by American seedsmen were tested, and the best methods of cultivation sought. On the whole, the cauliflower crop was found more profitable than any other, with the possible exception of peaches. There were partial failures, but these were due to causes which might have been foreseen and prevented. The experience gained at that time, and subsequent observation, have convinced the author that there are many parts of the country in which the climate and soil are adapted to this vegetable, but where its cultivation is yet practically unknown. The requirements for success with cauliflower will be found to be simple but imperative. A few direct experiments may be needed after one has gained the general information herein set forth, to enable one to determine whether it is best to continue or abandon its cultivation in his own locality. I have endeavored to treat the subject in a manner adapted to the diversity of conditions found within the limits of the United States. With no vegetable is it more important to have fixed rules for one's guidance than with the cauliflower; but these rules must of necessity be of the most restricted application; in fact, they require to be adjusted to almost each individual case. So, while I have not omitted to give minute, practical directions where they seemed necessary, I have endeavored to call attention to the circumstances under which they are to be employed, and must here caution the grower against following them too implicitly under different circumstances. This remark applies particularly to the selection of varieties and the dates of planting. Under the head of "Management of the Crop" will be found the most important information of general application, while in the chapter on "Cauliflower Regions" are given numerous records of experience from growers in all parts of the country, which will be found of special value for each locality.
