=Cultivation.=--Thorough horse cultivation between the rows should be supplemented by a hand-hoe between the plants in the rows. The cultivation must be good and continuous until the heads begin to form. =Diseases and Insects Enemies.=--Club root has been mentioned. It is a fungous trouble. The best remedy is new ground. The black flea on very young plants can be conquered with air-slacked lime or wood ashes. The cut worm is troublesome only in spring; not with late cabbage. The root maggot is sometimes very destructive, both with cabbage and cauliflower. New ground is the most satisfactory remedy. Green aphides or lice often follow lack of strength in the cabbage. Pyrethrum powder, air-slacked lime, kerosene emulsion, etc., are used as remedies for lice. The pyrethrum may be used dry or in water, at the rate of a tablespoonful to two gallons. The green cabbage worm, one of the worst of all enemies, can be pretty effectually checked by means of air-slaked lime dusted over the leaves. Other caterpillars yield to the same treatment. =Bursting.=--Bursting of cabbage heads is caused by a second growth, the result, perhaps, of continued wet weather, or warm weather following cold weather. The best remedy is to cut part of the feeding roots, either by close cultivation or with a hoe. =Selling.=--Cabbage prices vary between extremes that are far separated. Early cabbage usually sells at a good profit. Summer and autumn prices may be low. Winter and spring prices are almost always fair, and occasionally extra. Pennsylvania farmers sometimes ship to wholesalers in the cities and sometimes sell at public sale in the open field, in the autumn, just as the crop stands. The latter plan is an excellent one, where auction prices warrant it. It avoids the cost and risk of storage, as each buyer removes and stores his purchase. =Storage.=--Cabbage will bear much freezing without injury. The art of winter storage is to put it where it will have the fewest changes of temperature, and where it will be cool and damp without being wet. The most common practice is to cover two or three rows of inverted heads, with roots attached, with from 6 to 12 inches of soil, making provision for good drainage by ditches on both sides of the wedge-shaped heap.

This was the first Home-grown Cabbage in Philadelphia Markets.] This system may be modified so as to include six or more rows of inverted cabbage, the heap being flat instead of wedge-shaped on top. It does not turn water so well, but in practice is usually satisfactory. A good plan is to use about 6 inches of soil, and to add straw or litter as the cold increases. Under a steady low temperature it is no trouble to keep cabbage through the winter, but it is hard to provide against the many changes of our variable climate.
