Rich soil and steady feeding β corn is one of the hungriest garden crops. Skimp and you get small, poor ears.
Keep it well watered, especially as the silks appear β that's when the kernels fill. Drought = gappy cobs.
Pick when a punctured kernel runs milky, about 3 weeks after silks brown. Sweetness fades fast, so eat it fresh.
