Sweet Corn

Sweet Corn

Corn, Maize, Sweetcorn

Plant in blocks (4+ rows) not single rows for proper wind pollination. Direct sow after last frost 1" deep, 9–12" apart. Needs consistent moisture especially during tasseling/silking. Pick 18–24 days after silk appears, when silk browns. Use immediately after harvest — sugars convert to starch rapidly.
