How to ripen peppers off the plant

Why ripening peppers off the plant is limited

Peppers are generally classified as non-climacteric fruits, meaning they do not produce a significant ethylene surge after harvest and do not ripen further once fully green. The paper bag trick that works for tomatoes does not work for peppers — placing green peppers in a bag with a banana will not accelerate their color change.

However, research described at Garden Myths notes peppers behave as 'semi-climacteric': fruit harvested at or after the breaker stage — when color change has just begun — can complete ripening off the plant. Fully green, unripe peppers will not turn red; peppers showing the first flush of color likely will.

What the 'breaker stage' means

The breaker stage is the point at which a pepper first shows a color change — a hint of yellow, orange, or reddish-brown breaking through the green skin. At this stage, ripening processes inside the fruit are already underway and will continue without the plant.

Peppers harvested at this stage and kept at room temperature (around 70°F / 21°C) will typically complete their color change within 1–2 weeks. Flavor and heat in fruit ripened this way may differ slightly from fully vine-ripened fruit, but the result is usable.

Ripening individual peppers indoors

Place breaker-stage peppers in a single layer in a warm location — a sunny windowsill or a warm countertop at around 70°F works well. Warmth matters more than light; ripening occurs in darkness too.

Do not refrigerate peppers you are trying to ripen. Cold stops the process. Only move peppers to the refrigerator once they have reached the color and firmness you want.

1. Harvest peppers that have just begun to show color change (breaker stage) — avoid fully green fruit.
2. Rinse and dry them, then place in a single layer on a plate or tray.
3. Keep at room temperature, ideally 65–75°F (18–24°C), away from cold drafts.
4. Check every 2–3 days; most will reach full color within 1–2 weeks.
5. Once at desired color and still firm, move to the refrigerator and use within 1–2 weeks.

End-of-season strategy: pulling the whole plant

When frost is forecast and the plant carries green or partially ripe peppers, the most effective approach is to pull the entire plant rather than picking individual fruit. University of Maryland Extension advises pulling the plant just before a killing frost and hanging it upside down in a sheltered indoor space such as a garage.

Store in medium-cool conditions — 45–50°F with high humidity (around 95% RH) — for 2–3 weeks. The remaining fruit continues ripening slowly while still attached to the plant's stored resources. This method works better than placing individual green peppers on a countertop.

1. Check the forecast: act before the first killing frost (below 32°F / 0°C).
2. Pull the entire plant from the soil, roots and all.
3. Shake off loose soil, then hang the plant upside down from a rafter or hook in a garage, shed, or cool basement.
4. Aim for 45–50°F with good air circulation and some humidity — avoid a heated room, which causes shriveling.
5. Check weekly; harvest individual peppers as they ripen over the next 2–3 weeks.

What to do with peppers that stay green

Fully green peppers that show no color change will not ripen further indoors. Rather than discarding them, use them as-is: green jalapeños, green bell peppers, and green cayennes are all edible and flavorful at this stage.

Alternatively, green peppers freeze well. Dice or slice, spread on a tray to freeze individually, then transfer to a sealed bag. Frozen green peppers lose crispness but retain flavor and work well cooked.

Avoid these common mistakes

Do not use the paper bag or banana method — it is ineffective for peppers, which do not respond to ethylene the way tomatoes or avocados do.

Do not try to ripen peppers in the refrigerator. Temperatures below 45°F halt color development and cause chilling injury. Keep ripening peppers at room temperature until they reach your target stage.
