How To Keep Sweet Bell Peppers from Tasting Bitter

Peppers need lots of water when ripening to keep from tasting bitter.

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:

  • Ripening: Peppers grow sweeter as they ripen and turn from green to red, orange, yellow, or purple. For the sweetest peppers, be sure they’re fully ripe before picking.
  • Watering bell pepper plant.

  • Variety: Some varieties of peppers are sweeter than others. Red and orange peppers tend to be sweeter than purple or brown ones. And, if bell peppers consistently don’t grow well in your garden, there are plenty of other types of sweet peppers (with elongated shapes but similar flavor) that may do better.
  • Nutrition: Feed peppers once a month with a balanced, slow-release organic fertilizer or compost. Some growers also swear by epsom salts as a boost to pepper growth and flavor.
  • Soil pH: Like most garden veggies, peppers prefer slightly acidic soil with a pH of 5.5 to 7.0. Conduct a soil test to be sure your soil is providing the best growing conditions.
  • 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.

    I have fragrant plants that I buy at a nursery but not long after I have them home the fragrance disappears no matter how many new blooms come on line. What causes the loss of fragrance? Can anything be done to bring back the fragrance?

    Thanks
