Maintaining Your Root Cellar
A well-constructed root cellar will not need a lot of maintenance. If your root cellar is new, you will want to check the temperature and humidity every day just to make sure everything is where it should be. This way, you can then open or close vents as needed or add moisture if it is too dry. You will want to check your produce on a regular basis as well and remove any fruits and vegetables that are rotting or molding. This will help stop the problem from spreading to the rest of your stored items.
Once a year your root cellar should be thoroughly cleaned and aired out to help prevent plant disease or any insect infestations. Choose a dry day late in the summer when the shelves are nearly empty. Open the doors for two or three days to air the place, remove all the containers and shelves, wash them thoroughly with a bleach and water solution, and let them dry in the sun for a few days. If your cellar has a dirt floor, rake it to remove any debris; if it is cement, make sure you sweep and wash it well. Whitewash the walls as well. Your root cellar is now ready for a new season of fresh foods!
