Tomato Ripening Stages
  • Immature green: Fruits are neither developed inside nor in actual size.
  • Mature green: Fruits are developed inside with bright green color on the surface and reach in their actual size.
  • Breaker: Break the green color and show tarnish-pink or yellow color at the blossom end of tomatoes around 10% of the fruit surface.  
  • Turning: Up to 30% of the fruit surface turns to tarnish-pink, yellow, orange or other colors according to the tomato varieties.
  • Pink: Up to 60% of the fruit surface turns its color.

Usually, late-season tomatoes can hold various fungus and molds. So, don’t forget to wash your fresh green tomatoes with water or light bleach solution after harvesting. This will help to remove dirt, bugs, funguses and other molds that stick to the tomatoes.

Methods of Ripen Green Tomatoes

You may get many different ways to ripen green tomatoes indoor. Here I discuss some common methods to ripen your tomatoes.

1: Cardboard Box Method Through Wrapping Green Tomatoes in Newspaper

First of all, wash and dry to make your tomatoes sanitize from dirt, bugs and other fungi. Then collect some cardboard boxes as your demand.

Ripening Green Tomatoes in Cardboard Box,  Ripening Green Tomatoes by Wrapping Newspaper

Wrapping each green tomato in black and white newspaper and keep them into a cardboard box. It helps them to separate each other and absorb the extra fruit moisture. Besides it also reduces the chances of fruit rotting. Avoid using any colored newspaper because it contains harmful chemicals that often bleed over into the tomatoes. Don’t make more than two layers of tomatoes in a box.

Keep a semi-ripe banana or an apple inside the box to boost up the ripening process. If you want to ripe your tomatoes faster keep an unripe banana or apple inside the cardboard box.

You can also speed up or slow down the ripening process by simply controlling the room temperature.

For example, it will take around 18-28 days to ripen your mature green tomatoes if you keep them at 55° F room temperature. As well you can ripen them within 7-14 days if the room temperature is 77° F.


2: Paper Bag Method

The paper bag method is another way to ripe your green tomatoes. In this method-

  • Take a brown paper grocery or lunch bag based on your fruit volume.

This is the traditional way to ripen your tomatoes. If you have a handful of tomatoes you can apply this method. 

Ripening Green Tomatoes on Windowsill

In this method, you just keep your tomatoes in a sunny windowsill place them the stem side down. This will protect your tomatoes from the bruise and stop rolling.

You can also put your tomatoes into a net bag and hang them somewhere sunlight is available. Within a few days, they will be ripe.

I don’t encourage this method because your tomatoes may rot or not edible if you keep them on the sunlight for a long time. Tomatoes need warmth, not the light to ripe.


How to Use Immature Green Tomatoes?

Immature green tomatoes don’t develop inside properly once harvest them. Moreover, they don’t even develop a flavor like ripen tomatoes once ripe. Whatever that doesn’t mean they are wastage.

So, set aside your immature green tomatoes and apply different recipes. There are a lot of food recipes of green tomatoes that you can try like fried green tomatoes.


How Long Does It Take to Ripen Green Tomatoes Following the Above Methods?

There are three basic things to consider before counting how long it takes to ripen green tomatoes.

Presence of Ethylene Gas

Tomato produces ethylene gas naturally to ripen them. More ethylene gas means ripen tomatoes faster. So, adding fruits like apple, banana, avocados or some other fruits that release ethylene gas naturally helps the ripening process faster.

Besides, unripe banana or apple produce more ethylene gas than a ripe one. So this also matters how long it takes to ripen your tomatoes. 

Temperature

Tomatoes ripen better when the room temperature remains between 55°-77° F. If the room temperature goes down below 55° F or rise above 77° F then the ripening process will be slower.

Moreover, when the temperature goes lower than 50° F or higher than 86° F in both situations tomatoes stop ripening. 

So, make sure your room temperature is good enough to ripen your green tomatoes.

Tomato Ripening Methods

The duration for ripening your tomatoes also depends on the method you applied for ripening them. Different methods take a different length of time to ripen green tomatoes.

So, based on the above parameters your mature green tomatoes will take around 3-4 weeks to ripen if the temperature remains at 55° F. On the other hand, it will take around 1-2 weeks if the room temperature remains at 77° F.
