Buying fresh carrots from the farmer's market is great, but it sucks when they're limp and grody after a day or so. Slow down the process by cutting the greens off the ends of your carrots.

As food blog The Kitchn points out, the greens at the top of carrots will continue to suck the nutrients out of the carrot when you store them. Cutting them off can make them last longer. If you want to squeeze a bit more time out of them, The Kitchn also suggests storing them in a covered, water-filled container. In fact, a non-plastic container will work best.
