As summer winds down, many gardeners are left with green tomatoes stubbornly clinging to their vines. But don’t worry! With a few smart techniques, you can ripen those tomatoes quickly, either on or off the vine, or find creative ways to enjoy the ones that stay green.
Ripening Tomatoes On the Vine
To encourage your tomatoes to ripen on the vine before the first frost, try these techniques:
- Feed Regularly
- Use an organic liquid fertilizer rich in potassium every two weeks to promote ripening and strengthen plants.
- Trap Heat
- In cooler weather, close greenhouse doors and vents to retain warmth.
- Remove summer shading if your plants need more sunlight, but monitor for heatwaves to avoid overheating.
- Focus the Plant’s Energy
- About six to eight weeks before the first frost, pinch off flowers that won’t have time to mature into fruit.
- Prune the tops of indeterminate plants and remove unnecessary side shoots to stop vegetative growth.
- Optimize Light and Warmth
- Cut back overhanging branches or anything shading your plants.
- Clean greenhouse glass to let in maximum light.
- Harvest Strategically
- Leave tomatoes on the vine as long as temperatures stay above 55°F (13°C).
- Once temperatures drop consistently below this, harvest all fruits to ripen indoors.
Ripening Tomatoes Off the Vine
Green tomatoes can ripen indoors under the right conditions. Here’s how:
- Assess Ripeness
- Tomatoes showing a hint of color (blushing) are most likely to ripen.
- Fully green tomatoes with no color change are less likely to ripen successfully.
- Countertop Ripening
- Place blushing tomatoes in a bowl at room temperature. They don’t need direct sunlight—warmth is the key.
- Use Ethylene Gas
- Speed up the ripening process by pairing tomatoes with ethylene-producing fruits like bananas or apples.
- Place the tomatoes and a ripe banana in a paper bag or enclosed space, leaving room for air circulation to prevent sweating.
- Avoid Refrigeration
- Never refrigerate tomatoes while they’re ripening; cold temperatures will halt the ripening process.
