Why do jalapeno peppers crack?

Jalapeño peppers crack primarily due to uneven watering and rapid changes in temperature. When the plant experiences drought stress followed by heavy watering, the rapid uptake of water can cause the fruit to expand too quickly, leading to cracks. Additionally, environmental factors like high humidity and excessive heat can contribute to this issue. Proper watering practices and consistent environmental conditions can help reduce cracking in jalapeño peppers.
