Why are cucumbers bitter?

Cucumbers are a commonly enjoyed fruit, however their bitter taste can often be off-putting. So why are they bitter? Firstly, because of the presence of cucurbitacins, a naturally occurring toxin found in bitter cucumbers. Cucumbers become bitter due to too much nitrogen and moisture in the soil, varieties of cucumber that are subject to infection from viruses and mildews, or being exposed to too much heat and light. However, cucurbitacins can be neutralized by selecting young cucumbers and suffocating them. The overall advantages of bitter cucumbers are that they are an excellent source of dietary fibers, vitamins, and minerals, with potential health-promoting and healing benefits, as well as medicinal uses.

Each gardener seeks to get a high-quality crop, but sometimes everything can go wrong. Even with good care, cucumber fruits have a bitter taste. Do you know what this may be connected with? If you are also perplexed by such a problem, then study the information below about the reasons why cucumbers grow bitter.

Why do bitter cucumbers grow

Outwardly, one cannot distinguish bitter fruits. They have the same rich color and aroma. An unpleasant taste is felt when a person has already tasted a cucumber. Because of this, you can spoil any dish with just one ingredient. There is a way out – to cut off the peel, but after all, inside it are the very useful trace elements that are so necessary for a person. It remains only to determine the reason why the cucumbers are bitter, and eliminate it.

Cucumber Harvest

The manifestation of this taste is a consequence of the high content in the fruit of a special substance called cucurbitacin. A lot of it is in greenery, which is the protection of immature cucumbers from pests. Cucurbitacin is present in all types of these vegetables, but when its concentration rises, an unpleasant taste begins to be felt. The reason why cucumbers are bitter can even be a sharp change in weather conditions or damage to the lashes of the plant. The general factors that provoke this phenomenon are:

  • insufficient humidity inside the greenhouse;
  • cold water when watering;
  • low content of potassium and nitrogen in the soil;
  • excess of sunshine;
  • lack or excess of soil moisture;
  • the use of seeds from the back of the cucumber;
  • lack of regular watering.

Greenhouse varieties of cucumbers

This type of vegetables can be attributed to moody. Its homeland is the tropical forests of India, where the fruits are located under other plants. It turns out that for growing cucumbers can not be placed in direct sunlight. Gardeners are trying to arrange greenhouses or beds just where there will be more. This is wrong, because cucumber fruits do not like dry, hot weather. Although they are not intended for nighttime temperature drops. As a result of the effects of such differences, the vegetable is subjected to stress, and responds to it with the production of cucurbitacin.

As for the reasons why cucumbers are bitter in the greenhouse, several specific ones can be distinguished:

  1. Damage and entanglement of the lashes of the plant. In greenhouse conditions, they are limited by the frame of the building, because of which they can not grow freely. In addition, the crop is often harvested sloppy, which also leads to damage to the lashes..
  2. Too much sun entering through the walls of the greenhouse. In this case, it is recommended to whiten them with chalk..
  3. Ventilating the building in conditions of different humidity and temperature inside and outside.
  4. Insufficient humidity in the greenhouse. To eliminate this drawback, it is recommended to moisten the paths and walls of the building.
  5. Wrong temperature at different periods of cucumber growth. During fruiting, it should be above 28 degrees, and at the initial stage – above 18 at night and 20 in the afternoon.
  6. Lack of nutrition from the soil. Cucumbers need different trace elements in the complex. It should include potassium, nitrogen and phosphorus. The lack or excess of one of them is the reason why cucumbers in the greenhouse are bitter.

Greenhouse Cucumbers

Outdoor Cucumbers

The same factors as those listed above can provoke the appearance of bitterness in cucumbers outside the greenhouse. Along with them, there are several characteristic reasons for the appearance of such a taste:

  1. Sunlight, which cucumbers in open ground receive in abundance, so more often hothouses get bitterness.
  2. Uneven irrigation or cold water. It is typical for country plantings when gardeners spend their future crops with rare rides.
  3. Temperature differences. Heat during the day and cold at night have a stronger effect on open cucumbers than on greenhouse.
  4. Sowing seeds on low beds. These soil layers are more susceptible to temperature extremes and worse warmed up..
  5. The location of the beds near raspberries, blackberries, strawberries. These plants are considered to be aggressors who take all useful substances from the soil along with water.

Why are homemade cucumbers bitter?

Another special reason why cucumbers begin to be bitter is their variety. Scientists have found that some species are more likely to produce cucurbitacin, even with the slightest environmental change. Such varieties include Murom, Vyaznikovsky, Nezhinsky. To remedy this situation, breeders bred special types of cucumbers. They are called hybrids. Due to the content of specific genes, they are able to resist the production of cucurbitacin. You can find out about their presence by marking on the package. Although more often the reasons why the cucumbers are bitter are the factors described below.

Lack of moisture

Cucumbers are plants stenobionts that are accustomed to relatively stable environmental conditions. The slightest deviations of such an important factor as humidity from the “golden mean” cause them to have a bad reaction in the form of increased production of cucurbitacin. Like wild Indian tropical liana, it is used to moderately moist, warm and loose soil.

 

Excess water

Excess liquid during irrigation acts like a lack of moisture, and the cucumber acquires a bitter taste. The reason for this also lies in the historical roots of the plant, which is used to the temperate conditions of the Indian rainforest. If the rainy season is in your area, be aware that bitterness appears due to excessive moisture in the soil. To avoid excess water, it is recommended to water the cucumbers once every 2 weeks at the initial stage of growth and daily, when the flowering period has already begun.

Wrong watering

Non-compliance with irrigation rules includes not only the amount of water described in the previous paragraph. The temperature of the liquid also affects cucumbers. Water should not be too cold, because this vegetable does not like sudden changes. Only warm, settled liquid is suitable for cucumbers. You need to do this in good weather, because in the rain watering will lead to an excess of moisture.

Lack of fertilizer in cucumbers

The last reason why fresh cucumbers are bitter is the lack of nutrients in the soil. Cucumbers grow very quickly, and in large quantities, as a result of which microelements may not be enough. For this reason, gardeners should carefully consider fertilizing the soil with fertilizers. The main thing is not to use fresh manure. It contains too much nitrogen, and this will lead to bitterness. Fertilizers are applied only according to the instructions, but at the same time regularly, i.e. no less and no more, because an overabundance of nutrients also negatively affects.

Why salted cucumbers are bitter?

If cucumbers in the harvest give bitterness even under perfect agricultural conditions, it’s possible that you have chosen a variety with a high cucurbitacin content. Among these stand out:

  • Vyaznikovsky;
  • Murom;
  • Intolerable;
  • Donskoy;
  • Nezhensky.

    Why do cucumbers have a naturally bitter taste? Is it due to their specific genetic makeup, growing conditions, or is it a result of harvesting practices? I’ve always been curious about the science behind their flavor.
