What Makes Cucumbers Bitter

Cucumber plants contain a compound cucurbitacin, which makes the cucumbers taste bitter. Cucurbitacin is mostly found in the foliage as well as in the fruits. It is nature’s way to deter animals and protecting the fruit from getting eaten.

The more cucurbitacin, the more bitter the taste of the cucumber.

Are Bitter Cucumbers Safe to Eat?

Bitter cucumbers are mostly safe for most people. In some cases, a bitter-tasting cucumber can create mild digestive discomfort, known as a burp.

Some new cucumber cultivars do not contain this cucurbitacin, so they don’t taste bitter and don’t induce any burp. These are called burpless cucumbers.

Usually, the burpless cucumbers produce fruits with thinner skins and fewer seeds. You can eat them without peeling.

How to Remove Bitterness From Cucumber:

Cut the ends off the bitterness usually gets concentrated at the ends. Peel the cucumber to remove the remaining bitterness. The thicker the peel the less bitter will be the remaining fruit.

You can also rub the cucumber ends in a circular motion after cutting with the cut piece. It will produce some foam. Then remove the ends and wash the cucumber. It will reduce the bitterness.

If nothing goes right and it is too bitter to eat compost it. You rarely will have to do this.

Why Do My Cucumbers Taste Bitter This Year?

The cucurbitacin, produced in the cucumber plants protects the plant from animals and pests. Usually, it is concentrated in the roots and leaves and rarely affects the fruit.

But some hostile growing conditions can cause the cucurbitacin to spread in the fruit and resulting in bitter-tasting cucumbers.

This is why the same cucumber plant may produce perfectly fine sweet-tasting cucumbers one year and bitter-tasting ones in the next year.

There can be a few reasons why your cucumbers might be turning bitter.

Warm Weather:

More often than not, bitter cucumbers are the result of extreme heat. When there is a significant increase in temperature, it triggers their maturation process, and the lettuce starts bolting by sending out stalks and flowers. And the leaves will taste bitter.

Lack of Water:

Being a watery fruit, cucumbers need a lot of water to grow and maintain their sweet taste. Lack of water can cause a bitter taste in the fruit.

Lack of Nutrients:

Cucumbers eat a lot. So they also need their nutrients very quickly. A deficiency of nutrients can cause bitter-tasting cucumbers.

  • Make sure the plant is getting at least 6 hours of sunlight. Lack of sunlight can be a cause of bitterness in the fruits.
  • During extreme heat conditions, use shade clothes to filter light to the plants, so they won’t get scorched by the extreme sun.
  • Water well. Especially during a long period of dry weather. An inch per week is good for the cucumber plant.
  • Use mulch to cover the soil. It will keep the soil moist and cooler.
  • Keep the soil fertile. Cucumbers are voracious eaters, so there is always a possibility that the soil nutrients will deplete from time to time. Lack of nutrients can cause bitterness in the fruit. Use a good quality balanced fertilizer or compost to keep the soil enriched with nutrients.
  • Grow cucumbers on raised beds. It will help young plants avoid stress. Too much stress can cause bitterness.

  • Choose burpless or non-bitter varieties of cucumbers for growing.
