How to Ripen Green Tomatoes in Just 7 Days



By Benedict Vanheems, 2 September 2024

As summer fades and cooler days creep in, many gardeners face a familiar dilemma: Will my tomatoes ripen in time? Don’t worry—whether you’re looking to ripen tomatoes on the vine or indoors, this guide has you covered. Plus, I’ll share two delicious ways to transform green tomatoes into culinary delights!


Ripening Tomatoes On the Vine

Tomatoes ripen best on the vine, where they develop their fullest flavor. With summer drawing to a close, it’s essential to give your plants every advantage to finish ripening their fruits.

Maximize Sunlight and Heat

  • Trim Shade: Remove overhanging branches or shading that blocks sunlight.
  • Clean Greenhouse Glass: Let in as much light as possible to help plants thrive.
  • Trap Heat: Close greenhouse doors, windows, and vents on cooler days to maintain warmth.

Focus Plant Energy

  • Stop New Growth: Pinch off flowers and excess foliage on indeterminate (vining) varieties about 6–8 weeks before the first frost. This encourages the plant to direct its energy toward ripening existing fruits.
  • Feed Regularly: Use an organic liquid fertilizer rich in potassium every two weeks to support ripening.

Keep tomatoes on the vine as long as possible, but once temperatures drop below 55°F (13°C) consistently, it’s time to bring them indoors.


Ripening Tomatoes Off the Vine

Ripening tomatoes indoors is easy if you know what to look for:

  • Light Green Tomatoes: These are likely to ripen if they’ve reached full size.
  • Dark Green Tomatoes: These are less likely to ripen but can still be used in recipes.
  • Blushing Tomatoes: These fruits are already releasing ethylene gas, which accelerates ripening.

Ripen Like a Pro

  1. On the Counter: Place tomatoes in a bowl at room temperature. Warmth—not sunlight—is the key to ripening.
  2. With Bananas: Add a ripe banana or apple to the bowl or enclose them with your tomatoes in a paper bag. The ethylene gas emitted by these fruits will speed up the process.

Avoid refrigeration—it halts ripening and diminishes flavor.
