Growing notes

Sweet corn needs steady, even moisture — about 1 to 1.5 inches of water per week — and is especially thirsty during two windows: when it's putting up tall growth, and from tasseling through ear fill. Water deeply at the base rather than overhead to keep the foliage dry and reduce disease, soaking the root zone two or three times a week rather than a daily sprinkle. Drought stress at pollination causes missing kernels and stunted ears, the most common cause of a poor harvest. Mulch around the block to hold moisture and even out the supply. In sandy soil that drains fast, water more often; in heavy clay, water deeply but less frequently to avoid waterlogging.
