The age-old question that has puzzled gardeners and tomato enthusiasts for centuries: will picked green tomatoes turn red? The answer, much like the process of ripening tomatoes itself, is complex and multifaceted. In this article, we will delve into the world of tomato ripening, exploring the science behind the process, the factors that influence it, and the techniques you can use to coax your green tomatoes into turning a lovely shade of red.
Understanding Tomato Ripening
Tomato ripening is a natural process that occurs as the fruit matures. It is triggered by a series of complex biochemical reactions that involve the breakdown of chlorophyll, the production of ethylene gas, and the accumulation of lycopene, the pigment responsible for the red color of tomatoes. Ripening is not just a matter of color change, but also involves a transformation of the tomato’s texture, flavor, and nutritional content.
The Role of Ethylene Gas
Ethylene gas plays a crucial role in the ripening process. As tomatoes mature, they begin to produce ethylene, which triggers a cascade of reactions that lead to ripening. Ethylene promotes the breakdown of cell walls, the production of enzymes, and the accumulation of pigments, all of which contribute to the characteristic changes associated with ripening. Tomatoes that are picked before they are fully ripe will continue to produce ethylene, which can stimulate ripening after they are harvested.
The Importance of Light and Temperature
Light and temperature are also important factors that influence the ripening process. Tomatoes need light to produce the energy they need to ripen, and temperatures between 65°F and 75°F (18°C and 24°C) are ideal for ripening. Temperatures that are too high or too low can slow down or even halt the ripening process. For example, temperatures above 85°F (29°C) can cause tomatoes to become mealy and overripe, while temperatures below 55°F (13°C) can prevent them from ripening altogether.
Can Picked Green Tomatoes Turn Red?
Now, to answer the question on everyone’s mind: can picked green tomatoes turn red? The answer is yes, but it’s not a guarantee. The likelihood of a green tomato turning red depends on the stage of maturity at which it was picked, as well as the conditions under which it is stored. Tomatoes that are picked when they are mature but still green have a higher chance of turning red than those that are picked when they are immature.
Factors That Influence Ripening After Harvest
Several factors can influence the ripening of picked green tomatoes, including:
The stage of maturity at which they were picked
The storage conditions, including temperature, humidity, and light
The presence of ethylene gas
The variety of tomato

Will Picked Green Tomatoes Turn Red?
Picked green tomatoes can turn red, but it depends on their stage of maturity and the conditions they are stored in. Tomatoes produce ethylene gas as they ripen, which stimulates the production of lycopene and carotene, the pigments responsible for the red, yellow, and orange colors of ripe tomatoes. If green tomatoes are picked when they are mature but not yet ripe, they will likely turn red off the vine. However, if they are picked too early, they may not have the necessary sugars and acids to ripen properly.
The key to ripening picked green tomatoes is to provide them with the right conditions. Store them at room temperature, away from direct sunlight, and do not refrigerate them. You can also try placing them in a paper bag with an apple or banana, as these fruits emit ethylene gas, which can help stimulate ripening. Check on the tomatoes regularly, and once they start to turn red, you can move them to the refrigerator to slow down the ripening process. With the right care, picked green tomatoes can turn red and be just as delicious as those that ripen on the vine.
How Long Does it Take for Green Tomatoes to Turn Red?
The time it takes for green tomatoes to turn red can vary depending on several factors, including the variety of tomato, the stage of maturity when picked, and the storage conditions. On average, it can take anywhere from a few days to a week or more for green tomatoes to ripen. Some tomato varieties, such as cherry and patio tomatoes, may ripen more quickly, while larger varieties like beefsteak and Roma tomatoes may take longer. It’s also important to note that tomatoes will continue to ripen after they are picked, but the process can be slowed down or speeded up depending on the storage conditions.
To check if your green tomatoes are ripe, look for a few key signs. A ripe tomato will be slightly soft to the touch, but still firm enough to hold its shape. The skin will be a deep red color, and the stem end will come off easily. You can also check the color of the tomato by cutting into it slightly – a ripe tomato will have a juicy, red interior. If your tomatoes are not yet ripe, be patient and continue to store them in a cool, dry place. With time and the right conditions, they should eventually turn red and be ready to eat.
Can I Ripen Green Tomatoes in the Refrigerator?
While it’s possible to store green tomatoes in the refrigerator, it’s not the best place to ripen them. Refrigeration slows down the ripening process by inhibiting the production of ethylene gas, which is necessary for ripening. If you store green tomatoes in the refrigerator, they may not ripen at all, or they may ripen more slowly than they would at room temperature. However, if you have already picked green tomatoes and want to keep them fresh for a longer period, you can store them in the refrigerator to slow down the ripening process.
If you do choose to store green tomatoes in the refrigerator, make sure to keep them away from direct sunlight and heat sources. You can also try placing them in a breathable container or bag to maintain humidity and prevent moisture from building up. Check on the tomatoes regularly, and once they start to ripen, you can move them to room temperature to speed up the process. Keep in mind that refrigerated green tomatoes may not be as sweet or flavorful as those that ripen at room temperature, so it’s best to use them in cooked dishes or sauces where the flavor can be enhanced by other ingredients.
How Do I Store Green Tomatoes to Ripen Them?
To store green tomatoes and encourage them to ripen, you’ll want to provide them with the right conditions. Start by storing them at room temperature, away from direct sunlight and heat sources. You can place them on a windowsill or in a cool, dry place, such as a pantry or cupboard. Make sure they are not too crowded, as this can lead to moisture buildup and rot. You can also try placing them in a paper bag or breathable container to maintain humidity and prevent ethylene gas from escaping.
To speed up the ripening process, you can also try adding an ethylene-producing fruit, such as an apple or banana, to the bag or container with the green tomatoes. Check on the tomatoes regularly, and once they start to turn red, you can move them to the refrigerator to slow down the ripening process. Be gentle when handling the tomatoes, as bruising or scratching can damage the skin and prevent them from ripening properly. With the right storage conditions, green tomatoes should ripen within a few days to a week, depending on their variety and stage of maturity.
What are the Best Conditions for Ripening Green Tomatoes?
The best conditions for ripening green tomatoes are at room temperature, away from direct sunlight and heat sources. Tomatoes typically ripen best in temperatures between 65-70°F (18-21°C), with moderate humidity and good air circulation. You can also try placing them in a sunny windowsill, but make sure the temperature doesn’t get too hot, as this can cause the tomatoes to ripen too quickly or become damaged. Avoid storing green tomatoes in areas with drafts or extreme temperatures, as this can prevent them from ripening properly.
To create an ideal ripening environment, you can also try using a ripening box or bag specifically designed for fruits and vegetables. These products typically have breathable materials and absorbent liners to maintain humidity and prevent moisture buildup. You can also add an ethylene-producing fruit, such as an apple or banana, to the box or bag to stimulate ripening. Monitor the temperature and humidity levels, and adjust as needed to ensure the green tomatoes ripen evenly and develop their full flavor and color.
Can I Ripen Green Tomatoes Using Ethylene Gas?
Yes, you can ripen green tomatoes using ethylene gas. Ethylene is a natural plant hormone that stimulates ripening in fruits, including tomatoes. You can buy ethylene-producing products, such as ethylene gas generators or ripening powders, or use fruits that naturally produce ethylene, such as apples or bananas. Place the green tomatoes in a bag or container with the ethylene-producing product, seal it, and keep it at room temperature. The ethylene gas will stimulate the production of lycopene and carotene, causing the tomatoes to turn red and ripen.
However, be cautious when using ethylene gas to ripen green tomatoes, as excessive exposure can lead to over-ripening or spoilage. Start with a low concentration and monitor the tomatoes regularly, removing them from the bag or container once they start to ripen. You can also try using a combination of ethylene gas and other ripening methods, such as storing the tomatoes at room temperature or using a ripening box. Keep in mind that not all green tomatoes will respond to ethylene gas, especially if they were picked too early or are of a variety that is less sensitive to ethylene.
Will Green Tomatoes Ripen if They are Not Yet Mature?
Green tomatoes will not ripen if they are not yet mature. Tomatoes must reach a certain level of maturity before they can ripen, either on or off the vine. If green tomatoes are picked too early, they may not have the necessary sugars and acids to ripen properly. In this case, they may remain green or turn yellow, but they will not develop the full flavor and color of a ripe tomato. If you’re unsure whether your green tomatoes are mature, check for a few key signs, such as a slight softening of the skin, a sweet aroma, or a slight pinkish tint on the underside of the tomato.
If your green tomatoes are not yet mature, you can try storing them at room temperature to see if they will continue to ripen. However, if they do not show any signs of ripening within a week or two, it’s likely that they were picked too early. In this case, you can use them in cooked dishes or sauces, where their flavor and texture can be enhanced by other ingredients. Keep in mind that immature green tomatoes can still be delicious and nutritious, even if they don’t ripen to their full potential. They can be used in a variety of dishes, such as soups, stews, or fried green tomato recipes.
