If sown in hot-beds, care must be taken to harden the cabbage sprouts by gradual exposure to the air before transplanting, so as not to cause any serious delay in growth. In field-grown cabbage, likely to be used in part at least for stock feeding, the plants should stand from 24 to 30 inches apart, in rows not less than 30 inches apart. This gives room for the heads to increase in size and weight. Under these conditions an acre will produce from 7500 to 9000 plants. But on small areas, where the crop is intended for market, the plants may be crowded somewhat, to keep down the size and to secure an average weight of four to six pounds each. In this way an acre will bear 10,000 plants. Cabbage should be cultivated once in a week or ten days until the heads touch in the rows. If your cabbage is uniform in size, has few outside leaves, very little stump or core when cut open, closely packed leaves lapping in the centre, freedom from disease or insect injury, and is true to name and type, you should secure the uniform price of five cents a head in good markets. Cabbage suffers from many diseases and insects, and the gardener needs to be on the watch constantly if he is not to lose his crop after all his labor. The cabbage worm makes its appearance early, and should be destroyed at once; while for club-root, black rot, etc., rotation is our only usual remedy.[6] Different varieties thrive better in different localities. You must experiment in a small way, or find out what your neighbors have done, keeping a record of the sort that does best under your conditions, and then plant only that. Near New York City the Bergen Drumhead does wonderfully well, but in some western parts of the country it has less success. The Newark Flat Dutch, on the other hand, for an early cabbage, does well both east and west. For a late season variety the Premium Flat Dutch is excellent. To show the possibilities of profit in cabbage, Professor Bailey, in his “Vegetable Gardening,” quotes from an expert cabbage grower in Green Bay, Wis., as follows:—Assume that you have first-class land worth $200 per acre: Interest and taxes per year will cost, say $15.00 Forty loads manure at $1.00 per load. 40.00 Plowing and fitting the ground 3.00 10,000 plants at $4.00 per thousand 40.00 Setting and watering 5.00 After-cultivation 10.00 Harvesting and marketing 50.00 -------- Total $163.00 8000 heads sold at $3.50 per hundred 280.00 -------- Net profit $117.00
