How Long Do Tomatoes Last?

Using this method, tomatoes can stay fresh and firm for two to four months, depending on the variety and how well they were stored.
Some gardeners have even reported tomatoes still looking good into the fifth month.
The best part is when you take them out, they still taste like real, sun-ripened tomatoes.
A Few Tips to Keep in Mind
Make sure the wood ash you use is completely dry and comes from clean, untreated wood. Ash from painted or treated materials can be toxic and should be avoided.
Only store firm, ripe tomatoes without any cracks or blemishes. One bad tomato can spoil the whole batch, so inspect them well.
Specially, keep the box in a cool, dry, and dark spot like a pantry or cellar. Check every few weeks, and if the ash feels damp, swap it out for fresh, dry ash to keep the tomatoes well protected
