To store carrots properly, you can refrigerate them, or store them in a root cellar. Canning, freezing and dehydrating are also proper storage methods. Carrots stay the longest if canned.
Carrots store longer in the fridge if kept above 32 degrees Fahrenheit. Prep them by brushing off the soil, making sure not to wash the soil as it helps slow decay. Dry the carrots in the sun for less than half a day. Then cut the tops off next to the root, and put them in a plastic bags with holes in them.
To store them in a root cellar, you need to pack them in slightly damp sawdust or sand in containers or Rubbermaid tubs. Drill holes on the lids, and check on them once in a while. You can store them up to six months using this method as long as the temperature is just above 32 degrees Fahrenheit and 95 percent humidity.
Carrots retain their vitamins the most if frozen, but this can be expensive as it requires a lot of electricity to keep the freezer cold. Canning is tedious, and the carrots lose a lot of vitamins, but if properly canned, they stay good for several years.
Dehydrated or dried carrots take less space compared to other storage methods, and you store the powder in airtight glass jars with metal lids.
