Protecting Pepper Plants from Early Frost and Ripening Fruit

Introduction

When frost threatens but peppers are still producing, quick action can save both plants and fruit.

Frost Protection for Peppers

Cover plants with blankets or row covers when temperatures dip to 34–37°F. These temps are above freezing (32°F), so covers provide enough protection. Peppers can sometimes survive brief 29°F nights, but fruit may be damaged.

Harvesting Before Frost

Pick all mature peppers before a freeze. Green peppers will not ripen well off the plant.

Ripening Peppers Off the Plant

For nearly ripe fruit, pull the entire plant and hang it upside down in a garage or basement. Peppers will continue to ripen on the plant.

Conclusion

Cover plants for light frosts, harvest all you can, and hang whole plants to ripen remaining fruit indoors.
