What to Do with Green Tomatoes: From Harvest to Ripening

Growing your tomatoes in metal raised garden beds gives you an advantage. Because these metal beds, to some extent, are easier to manage late-season harvests and keep the soil inside warmer.
In this guide, we will discuss practical strategies to handle green tomatoes after frost, harvesting skills, and efficient indoor ripening methods.
When to Pick Green Tomatoes Before Frost

Green tomatoes are highly vulnerable to cold damage, especially during sudden overnight freezes. Once nighttime temperatures consistently fall below 45°F, you should begin checking the plants regularly. Firm, glossy, and nearly full-sized tomatoes are considered mature green and are suitable for indoor ripening. In contrast, very small, hard, and deep-green fruits are classified as immature green tomatoes. These will not ripen well indoors but can still be used in cooking.
You would be surprised at how many plants thrive when grown on trellises. It is way easier to harvest when the fruit is hanging down and within reach - no more kneeling or rummaging through leaves on the ground! It is just such a practical way to garden!
Ripening & Storing Green Tomatoes

Frost often leaves gardeners with more green tomatoes than expected. Fortunately, there are several proven ways to ripen or store them so they don’t go to waste.
The first step is to check the condition of each fruit before deciding how to use it. Tomatoes that remain firm, and unblemished are generally still usable. While, fruits that appear soft, translucent, or mushy have likely sustained freeze damage and should be discarded. Below are the most reliable methods for handling your late-season harvest.
Best Methods to Ripen Green Tomatoes After Frost
If frost arrives before your tomatoes fully ripen, bringing them indoors is one of the best solutions. Many gardeners search for how to ripen green tomatoes indoors, and the process is simpler than you might think.
- Use a paper bag or cardboard box: Place mature green tomatoes in a breathable container such as a paper bag or cardboard box. This helps trap ethylene gas, which speeds up ripening.
- Add a banana or apple for faster ripening: Bananas and apples naturally release ethylene gas. Pairing them with your tomatoes is considered one of the best methods to ripen green tomatoes after frost.
- Avoid direct sunlight: Contrary to popular belief, sunlight does not help ripen green tomatoes indoors. Instead, store them in a cool, dry area with good ventilation.
- Ideal temperature: Keep tomatoes at 55–70°F. Lower temperatures slow ripening, while warmer temperatures may cause uneven softening.
Regularly check for any signs of rot and remove spoiling tomatoes to keep the rest in good condition.
Tips for Consistent Ripening

- Control temperature and humidity: A stable environment prevents moisture buildup and reduces the risk of mold.
- Spread tomatoes in a single layer: Air circulation is essential. Avoid stacking tomatoes, especially if they vary in maturity.
- Inspect tomatoes frequently: Check every few days for soft spots or mold. Removing affected fruit prevents spoilage from spreading.
These natural ripening methods are useful when you have a large harvest or want tomatoes to ripen slowly for extended use.
