Bite into a cucumber and, instead of crisp deliciousness, you get a bitter taste. What happened?!!?
Fruit can turn bitter for several different reasons. Unfortunately, once a plant produces bitter tasting fruit, you may as well cut it off at ground level and start again, because most of the fruit it will produce from then on will have the same taste. Also, the chemicals that cause the bitterness can make you sick. In extreme cases, they can even kill you. So, what makes fruit turn bitter and how can it be prevented?
Causes of bitter fruit
The bitterness is caused by chemicals, called cucurbitacins, that are always present in the roots, leaves, and stems of these plants. When the plant becomes overly stressed, it increases the production of cucurbitacins, which then make their way into the fruit. Scientists believe these chemicals are intended to discourage feeding by herbivores (and us). Common causes of stress that leads to bitter fruit include:
Steps to prevent bitter fruit
If your cucumbers have started turning bitter, you can still eat much of the fruit, simply by peeling it and tossing the stem end into the compost pile. If it still tastes bitter, compost it. The chemicals will disperse and break down.
Help your cucumbers, melons, and summer squash stay sweet with proper irrigation and a little sun protection.
