Harvest: Sweet corn is ready for harvest about 20 days after first silks appear. Husk will be green. Puncture kernel. If the liquid is clear, the corn is immature; if it's milky, it’s ready to pick. The best time of day to pick is right before eating. Or, pick in the early morning when temperatures are cool to prevent buildup of field heat, causing sugars to convert to starch.

Tips: Mulching is useful because adequate moisture is necessary from time of pollination to harvest to make sure ears are well filled.
