Quick Ways to Ripen Tomatoes Indoors: Expert Tips by Karat Farms

Introduction


Sometimes, tomatoes need a little extra help ripening, whether due to cooler weather, a sudden frost, or simply being picked early. Fortunately, ripening tomatoes indoors is easy and ensures they reach their full, delicious potential. With a few tried-and-true methods, you can enjoy red, juicy tomatoes right from your home. Here’s a guide to ripening your tomatoes quickly and effectively indoors.


1. The Paper Bag Trick


One of the easiest methods is placing tomatoes in a paper bag. Paper traps ethylene gas—an essential compound that fruits naturally release as they ripen—creating a mini ripening chamber.


  • How to do it: Place tomatoes in a brown paper bag and fold it to close. Keep the bag at room temperature and check daily to ensure the tomatoes don’t over-ripen.

  • Pro Tip: Add a ripe banana or apple to the bag to produce even more ethylene, helping tomatoes ripen faster.

This method works best with tomatoes that are already turning from green to pink.


2. Warm Them Up Near Sunlight


Temperature plays a crucial role in ripening, so a sunny, warm spot works wonders. However, it’s best to avoid direct, harsh sunlight, as this may dry out or damage the tomatoes.

  • How to do it: Place the tomatoes in a shallow bowl or on a clean dish in a warm spot that receives indirect sunlight, such as a windowsill.

  • Pro Tip: Turn the tomatoes every day to ensure they ripen evenly on all sides.

This method is ideal for small batches or individual tomatoes.


3. Use a Cardboard Box for Larger Batches


If you have a significant number of tomatoes to ripen, the cardboard box method offers a convenient solution. It’s similar to the paper bag trick but better suited to larger quantities.


  • How to do it: Line the bottom of a cardboard box with newspaper, arrange tomatoes in a single layer, and cover with another layer of newspaper. Close the box and store it in a warm, dry spot.

  • Pro Tip: Check the tomatoes every couple of days to make sure they’re ripening without signs of spoilage.


This approach keeps tomatoes safe and lets you ripen a big batch at once.


4. Hang the Entire Vine Upside Down


If frost or weather conditions require you to harvest tomatoes before they’re fully ripe, consider hanging the entire vine upside down. This unique method helps tomatoes ripen naturally, similar to how they would on the plant.


  • How to do it: Pull up the entire plant, remove excess dirt, and hang it upside down in a cool, dry location, like a basement or garage.

  • Pro Tip: This method works best if the tomatoes have started to turn slightly red before picking.



Great for green tomatoes still on the vine, this method offers a natural way to ripen them slowly.


5. Place in a Fruit Bowl with Ethylene-Producing Fruits


This is one of the simplest ways to ripen tomatoes indoors and works particularly well with just a few tomatoes. Other fruits like apples and bananas release ethylene gas, which speeds up the ripening process.


  • How to do it: Place the tomatoes in a bowl with ripe bananas or apples and leave them in a warm, dry spot.

  • Pro Tip: Avoid overcrowding the bowl, as this can lead to bruising and potential rotting.

This method is perfect for a few tomatoes that need an extra boost in ripening.



Ripening tomatoes indoors is an easy way to get the most out of your garden’s harvest, even if weather conditions or timing didn’t align. With these methods, you can enjoy ripe, delicious tomatoes that are just as flavorful as those ripened on the vine. Try one or mix a few methods to find what works best for your setup.
