I pulled all my green tomatoes in Mid October right before it frosted real hard. I put them in a box wrapped in newspaper and put them in the basement. I have done this for several years now and this method works pretty good for preserving and saving the green tomatoes for use later.
This photo is of a few of my tomatoes that I am still pulling out of the box this week for use. Some are a bit wrinkled but they sure taste much better than those store-bought plastic tasting tomatoes that you get at the store this time of year.
A few tips if you try this wintering over idea. Check the tomatoes frequently to remove any overripe or spoiling tomatoes from your storage box or bag. I normally just cut off the bad part if any and use the remaining tomato in making sauces or condiments. Also make sure you keep the box or bag in a cool, dry and dark basement or area for storage. I found this works best. This year I used long, low boxes which I found worked out very well for the tomatoes to be stored. If you stack tomatoes on top of each other they tend to spoil faster in my opinion. Use newspaper to wrap them separately as this helps extend the wintering over process.
It truly is enjoyable to eat my own fresh tomatoes in January from last year’s garden. I plan to expand on this wintered over tomato idea again this year.
