How to Ripen Green Tomatoes
Once night time temperatures start dipping into the low 70s F, you probably aren’t going to get any new fruits forming. To speed up ripening of the existing green tomatoes, pinch off any new flowers.
- Lift the entire plant and hang it in a dry, sheltered location, like the garage. The fruits will continue to ripen and will still have some of the benefits of ripening on the vine. Try and take some roots with the plant, but you can shake off any soil. Don’t hang the plants in direct sunlight or total darkness.
- Ripen inside the house. These will have a tinge of color at the blossom end and feel a little softer than the solid young fruits.
- Place them on a sunny window sill. Although the tomatoes are more stable sitting on their stem side, they will rot less readily if you can place them blossom side down.
- Wrap individual green tomatoes in newspaper and layering in a box, no more than two layers deep. Place the box in a dark, dry spot and check weekly for progress. It usually takes 3-4 weeks for the tomatoes to ripen.
- Placing the green tomatoes in a paper bag with a ripe apple.
