Many vegetables will keep for months in cold storage, if you can provide the right conditions. Here are some tips to store them. Store only fully mature vegetables. Immature fruits and vegetables will rot quickly. Hold off harvesting as long as possible, especially with root vegetables that can withstand some frost. Do not store vegetables that have been bruised or nicked or that show the slightest sign of rot. Be careful when handling them. Remove all excess soil. Don’t wash the vegetables, just let them dry and brush off the soil. You can wash them well before using them. Thoroughly clean your storage area before each use.
