As temperatures dip at night, the ripening process of your garden tomatoes slows. Cold is clearly not their environment. Maybe some of your tomatoes fell off the vine as a result of a bit too much trimming. Not to worry! When tomatoes are brought inside, they may be coaxed to ripen from green to red. To ripen, tomatoes need warmth rather than sunlight. Thus, keep your tomatoes warm (an indoor temperature of approximately 70o F is ideal) to transform them from green to red.
4 Methods To Ripen Green Tomatoes Indoors
Then, choose ripe fruits that are full—or almost full—size and softened a little with a flush of color on the blossom end. It’s better not to wash them after they’re inside, unless you’re hoping to rescue a fruit after losing the plants to illness (be sure to dry thoroughly). Alternatively, wait until you’re ready to eat them before washing them, since any moisture left on the tomato might turn to mold.
Then attempt the following techniques to make green tomatoes red:
1. Paper Bag Method
Put a few green tomatoes in a paper bag, seal it, and keep in a warm place to ripen. By enclosing tomatoes together, the ethylene they generate will encourage ripening. You can add a ripe banana or apple as well to speed things up. When a tomato is ripe, take it out of the bag and eat it immediately away. Check the bag daily for mold or rot and remove any spoiled pieces.
2. Box Method
If you want to ripen multiple green tomatoes, try using a cardboard box. Put them in the box so that they do not touch. You may also include a ripe banana. Close the box and, as with the bag-ripening method, check daily for mold and rot, or full ripening, and remove those tomatoes.
3. The Windowsill Approach
If your tomatoes have already begun to mature, give this a try. Just place them on the window sill of a window that receives sunshine. Check on their development on a daily basis. You can also remove tomatoes you have ripening in a bag or box once they start showing signs of color and continue their ripening on the windowsill.
4. Hanging Upside Down Method
Some gardeners remove the whole plant – roots, fruits, and all – and hang it upside down in an indoor setting. According to the notion, the plant will devote all of its available energy to the fruit while it is still alive. Before hanging, brush off as much dirt as possible, and then monitor the progress everyday.
Keep in mind the following:
- Tomatoes ripen best when a portion of the stem is left on.
- Fruit should ripen in 7-14 days or less using these procedures.
- Green tomatoes that have not yet matured will not ripen after being harvested.
- These techniques do not improve taste. No tomato will ever taste as good as a field-ripened tomato. Nonetheless, it is preferable than letting them go to waste.
- Throughout the indoor ripening phase, keep tomatoes at room temperature. Do not refrigerate them, as this will ruin their flavor.
Will hard green tomatoes ripen when picked?
If you see a hint of red on your green tomatoes, selecting them separately and bringing them indoors may be the best way to get them to mature. Like many fruits, tomatoes continue to ripen once they’ve been picked.
Can you ripen green tomatoes off the vine?
Tomatoes Can Ripen Off the Vine? Green tomatoes may be ripened inside as long as they are maintained at normal temperature. Tomatoes begin to ripen on the vine and continue to ripen after being harvested because they release a gas called ethylene.
Why are my big green tomatoes not turning red?
As temperatures exceed 85°F, the plants stop producing lycopene and carotene, the two pigments responsible for the color of ripe tomatoes. If your area has hot temperatures for an extended period of time, the ripening process might stop and you could end up with tomatoes that are yellowish-green or orange.
Can you pick green tomatoes and let them ripen the sun?
Tomatoes and other ripening fruits, such as bananas, apples, and avocados, depend on ethylene gas to ripen, not sunshine, which is why Cunningham advises keeping green tomatoes in a limited, temperature-controlled space after picked so they can continue to grow.
