• Carrots are mature at around 2 ½ months and ½ inch in diameter. You may harvest whenever desired maturity is reached.
• You may leave mature carrots in the soil for storage if the ground will not freeze.
• To store freshly harvested carrots, twist off the tops, scrub off the dirt under cold running water, let dry and seal in airtight plastic bags, and refrigerate. If you simply put fresh carrots in the refrigerator, they'll go limp in a few hours.
• Carrots can be stored in tubs of moist sand for winter use.
