Harvesting: For best flavor and texture, harvest carrots any time before, and until they reach their optimal size. Peak harvest period lasts about 3 weeks, longer in the fall. Late summer-sown carrots are sweetened after having been kissed by light frost; however, harvest before soil freezes, which may destroy the crop. In USDA zone 5 or warmer, carrots can be left in the ground for storage provided they are heavily mulched; harvest as needed on days the ground is not frozen.
