A basement root cellar is something many of us dream of having – the ideal root cellar where we can venture into its chilly depths and gather fresh fruits and vegetables held over from the summer season. The reality is that it isn\u2019t a possibility for most of us. But even if you don\u2019t have the means or the space to build a model of perfect cold storage, the good news is you can create a highly functional system right in your home.<\/p>\n

What You Need for a Basement Root Cellar<\/h2>\n

The magical combination of temperature and humidity for proper basement root cellar storage depends on the particular type of fruit or vegetable you wish to keep in long-term storage. For example, root crops, such as potatoes and carrots, do exceedingly well when kept in an area roughly 32 degrees F with a 90- to 95-percent humidity level. Under these conditions, you can feasibly keep them until the following late spring or early summer. Squashes, including pumpkins, with their durable outer skins, need a slightly warmer temperature ranging between 50 to 55 degrees F and relatively dry conditions at 50- to 60-percent humidity. Given this environment, you can enjoy them well into the winter and sometimes into the spring. Once you know what produce you want to store, you can determine how to go about creating an environment where they\u2019ll keep well.<\/p>\n

Identifying Your Storage Area<\/h2>\n

Begin by looking at the setup of your basement to determine the best location to create a basement root cellar with a small cold-storage room or storage area. You\u2019ll want a place that\u2019s cool and properly ventilated. Be mindful to keep away from heat sources, such as the furnace or hot-water tank. Having a wood-burning or pellet stove in the basement can present a few challenges, though it doesn\u2019t preclude you from successfully storing fruits and vegetables for the long term.<\/p>\n

Ventilation is important in a basement root cellar because it allows fresh air to enter the room, as well as letting ethylene, a naturally occurring gas expelled by the fruits and vegetables during the ripening process, to escape. Without proper ventilation, your produce will break down at a faster rate. If you\u2019re able to locate an area with a window, this is ideal. The window can be covered to block out light and opened on occasion for passive ventilation. You can also install a PVC ventilation pipe through the window opening to allow for consistent passive ventilation, or use a small fan (like you would in a greenhouse) attached to the PVC pipe to pull gases out of the cold storage. If the best storage area in your basement isn\u2019t near a window, the other option is to drill a hole through the wall and insert a ventilation tube.<\/p>\n

Building the Cold-Storage Room<\/h2>\n

Once you\u2019ve determined your location and ventilation options, your next considerations are the walls and insulation. Concrete blocks with rigid foam insulation can create a snug storage space, though you might find it easier to build the walls out of 2×4 lumber with 3\u00bd-inch fiberglass insulation sandwiched in between. Use faced insulation\u2014the kind with the foil paper on one side\u2014if possible; otherwise, add plastic sheeting as a vapor barrier. It\u2019s not necessary to put insulation on the exterior wall (aka the basement wall), but you will want to put it on the ceiling and along the walls dividing the basement root cellar from the rest of the basement.<\/p>\n

Regulating your temperature and humidity can be as easy as opening a window or the vent. Many people take advantage of the cool fall nights to allow cold air to pour into the room, ultimately bringing down the temperature to the desired range. Humidity, which is a challenge in drier regions of the country, can be bolstered by setting a pan of water in the room.<\/p>\n

The ideal temperature and humidity you want to maintain depends on what you want to store. If you\u2019re storing several items, consider what you have the largest amounts of and make that your baseline gauge. Below is a chart of commonly stored fruits and vegetables, their ideal storage conditions, and how long they keep. Use this as a reference point when making your basement root cellar decisions.<\/p>\n

Containing Your Produce<\/h2>\n

Build shelves to hold burlap bags of produce, or create bins to keep everything in place. Here are some additional tips to keep in mind when working with specific produce in a basement root cellar.<\/p>\n
