Why do my sweet bell peppers taste bitter? Is there any way to improve the flavor?
If your supposedly “sweet” peppers taste bitter, the most likely culprit is lack of water. Pepper plants need to be consistently moist. Drought-stressed peppers go into survival mode, hastily ripening fruits and seeds without putting much energy into flavor. The resulting peppers are thin-walled and bitter.
Keep your plants well watered, especially after they’ve started setting fruit, and even more especially during the hottest months. In addition to not getting enough water, some other possible causes of bitter peppers are:
- Temperature: Even though peppers are warm-season veggies, they still suffer when temperatures soar over 90° F. In addition to watering, be sure to mulch your plants to keep the soil cooler than the stems. It might also help to provide a bit of light shade during the hottest months, to prevent sunburn.
