Good ways to store fresh carrots at home include placing them in water or sand. To keep carrots at least one month in the refrigerator, first remove their greens. Place the carrots in a container, fill it with water, and cover it. Change the water every four to five days.
To keep carrots for up to six months, put unwashed carrots in a container covered with sand, and store them in a cool, airy location. In addition, growers can keep carrots in the ground as long as the plants are covered by mulch. Pull the carrots when the ground starts freezing.
