Ripening Bananas on the Plant in a Cool Climate

In Kentucky, banana plants in the ground won't ripen fruit before frost. Leave the stalk on as long as possible; harvest when nights approach 40°F. Place the whole hand in a cardboard box with a couple of apples—apples emit ethylene gas that speeds ripening.

Flavor depends on maturity at harvest; they may be starchy or sweet. If unpalatable, compost them—banana peels enrich soil. For reliable fruit, grow bananas in large pots and overwinter indoors (they make dramatic houseplants).

Grandmother's tip: bury banana peels around roses for potassium.
