Harvesting: Corn is ready about 3 weeks after the silks appear. Harvest when the silks are brown, but not dried, and the husks are dark green; ears should be plump, and rounded rather than pointed at the tip. To test for ripeness, gently pull back the husk and pop a kernel; the liquid should be whitish; if it is still clear, ears are not quite ready.
