Start with tomatoes that are ready to finish

Yes, some green tomatoes can ripen after picking. The best candidates have reached their normal size and changed from deep green to a lighter, whitish green. Fruit already showing its first blush of color is also worth bringing inside. Small, immature fruit is less dependable. Iowa State Extension

For gardeners in Galion and nearby communities, the useful question is less “How many green tomatoes are left?” and more “Which ones are far enough along to save?”

Harvest before frost

Watch your local forecast rather than relying on a particular calendar date. Bring the remaining harvest indoors before frost reaches the plants. University of Minnesota Extension recommends harvesting the fruit before the first frost. Growing tomatoes

Choose sound fruit from healthy plants. Remove stems so they cannot puncture neighboring tomatoes. If fruit needs washing, let it dry completely before putting it away. Iowa State Extension

Give them a simple indoor setup

Arrange larger green tomatoes in a single layer with space between them. A shallow tray or box makes it easy to see what you have. Choose a location around 65–70°F, away from direct sunlight; a dark location works. Oregon State Extension recommends this approach for finishing larger green tomatoes indoors.

Check the tray every few days

Remove spoiled fruit and take out tomatoes as they ripen. Mature-green tomatoes may ripen in roughly two weeks at 65–70°F, but timing varies. To encourage ripening, place suitable fruit in a ventilated bag or box with a ripe tomato. Avoid treating a predicted number of days as a guarantee. Iowa State Extension

Make the last harvest count

A final tomato harvest doesn’t have to be an all-or-nothing project. Start with the strongest candidates, give them a manageable place indoors, and keep checking their progress.
