Produce Storage Tips

Tips and Guidelines on How to Store Your Fall CSA Vegetables

Apple Storage:

30-34°F in 90%-95% relative humidity

Before long-term storage sort apples thoroughly to remove any bruised or punctured apples.  As the old saying goes, “One bad apple spoils the bunch”.

Place apples in a plastic bag to maintain proper humidity prior to storing in the refrigerator.  Can also be stored in a humid cellar that maintains a cool temperature below 40°F or in unheated garages if insulated from freezing temperatures by a Styrofoam chest, hay or other insulating material.  Be aware that these are difficult conditions to match in a modern garage or cellar so storage in your refrigerator is the best option.

Apples will begin to deteriorate if exposed to water or freezing temperatures.
