We have officially entered the fall season, and here in Massachusetts, we are still experiencing plenty of sunshine and warm days. When Does Corn on the Cob Season End in Massachusetts? I started wondering when the corn on the cob season ends in Massachusetts. There's no official date that the corn on the cob season ends, but the general consensus is that the season wraps up in early October. However, the season can stretch a few weeks into October as long as there hasn't been a hard freeze.
