是一个沉重的喂食者. 直接播种，1-1.5″ deep, 5-10″ apart on a row spacing of 30-36″ apart. For best results, plant in blocks or 3-4 rows, instead of 1 long row. Isolate different corn varieties by a distance of 100-150′ or by maturity. Keep soil moist and weed free. After corn is a foot tall, we like to add Bradfield fertilizer at the rate of 5 lbs per 100′ row, right on row just before tilling or cultivating soil. If you use a chemical fertilizer, do not put it on row or you may burn plants. HARVEST: When kernels are full, but still in the milky stage, pick ears from plants. Husk and use fresh, can, dry or freeze for later use. You will need 1/4 LB (500 seeds) per 100′ of row or about 10 pounds per (25,000 seeds) acre.
