Green Side Up's Richard Hentschel covers common storage of root crops right in the garden and places to store hard rind, or winter, squashes in the home until you can prepare them for the family. Carrots and other root crops do just fine if left in the garden and harvested as needed. Winter squashes prefer storage temperatures between 50 and 55 degrees. They do just fine even 10 degrees warmer, but they may not last as long that way. Cooler, they can last for 4 or more months.
