This standard winter vegetable may be stored either indoors or out. In the former case a good way is to put the trimmed heads in slotted or open vegetable barrels. Or the plants may be taken up roots and all, the loose outer leaves trimmed off, and three or four heads tied together by the roots and suspended from nails in the cellar rafters. In this way they will keep well without occupying any floor space, which is needed for other things, such as root crops and fruits. For this purpose, ordinary corn ties made of stout cord, with a wire clamp at one end which saves the trouble of tying and untying the string, may be utilized to good advantage. Cabbage to be stored out of doors may be kept either with the roots on, or in the form of trimmed heads. The method of packing is shown in the accompanying cut. It is well to store at least part of the crop out of doors, as this will keep in perfect condition until late spring, when it will be much more fresh and crisp than that which has been stored indoors.
Fig. 29 - Well matured cabbage can easily be kept through the winter in an outside trench or pit. The heads are packed as shown, covered with straw or marsh hay, and as freezing weather approaches, gradually cover with soil. It is important not to put the soil on at first, as this will cause them to heat and spoil.
