Cut off the tops (they will suck water and nutrients out of the carrot). Put in a loose, perforated plastic bag, preferably twisted shut, in the crisper/vegetable drawer of your fridge. To be extra certain they will not dry out, you can add a damp towel to the bag, or place them in closed container with plenty of moisture. Alternatively, you can store the carrots in a covered container filled with water.
(Kale, Swiss chard, Bok choy, Beet greens) Remove any bands, twist ties, etc. from the stems. Greens should be stored in a loose, perforated plastic bag, preferably twisted shut, in the crisper/vegetable drawer of your fridge.
POTATOES & BEETS
store in cool, dark and dry place, such as, a box in a dark corner of the pantry; a paper bag also works well. Do not wash them before storing, or make sure to let them dry out (if still wet from washing) before storing.
