The yellow color of the fruit of the cucumber is a sign of its maturity, so this phenomenon is normal. For salads and for salting, we use immature greens. However, in the event that the ovary on the cucumbers turns yellow, not everything is in order with the plant, and certain measures must be taken. We will consider ways to combat this ailment later in the article. The ovaries of a cucumber turn yellow for several reasons.
Most often this happens due to a lack of nutrients when the plant cannot get all the components it needs. Usually, you just need to fertilize the plant with preparations containing various kinds of mineral substances. The ovaries of a cucumber turn yellow most often if there is a lack of elements such as phosphorus and potassium in the soil.
The second factor leading to a similar result may be too abundant fruiting. In this case, the cause is even easier to eliminate. You just need to pinch off the extra ovaries. This will allow the plant to form a new, healthy and appropriate color.
Another reason why the ovaries of cucumbers turn yellow can be called the fact that the flowers were not pollinated. If the bed is small, additional pollination can be done with a brush, gently transferring pollen from male plants to the female pestle. Large plantations are best pollinated by attracting bees in any way.
The ovaries of the cucumber also turn yellow due to the low temperature at night. The fact is that the
fruits of this plant grow precisely in the dark period of time of the day. Therefore, the air at night should warm up at least 18 degrees above zero. With large temperature fluctuations, cucumbers are best protected with a film or some modern non-woven covering material.
Infection with some diseases and insect attack can also be an answer to the question of why the ovaries of cucumbers turn yellow. Damage to plants by infections such as root rot, powdery mildew, peronosporosis, fusarium wilt , etc., can lead to a similar result. In order to protect plants from such diseases, it is necessary to observe some important rules. Firstly, in no case should you plant cucumbers in the same place from year to year. Secondly, maximum attention should be paid to plants - watering, weeding, feeding and loosening on time. The likelihood of disease of strong cucumbers is much less than weakened.
Well, the most common reason is insufficient watering. The ovaries of a cucumber turn yellow if the plants lack nutrients as a result of a lack of water. It is almost impossible to eat such fruits in food, since they have a pronounced bitter aftertaste. This is due primarily to the fact that
cucumber juice is saturated with potassium, cucurbitacins, iodine and magnesium.
There can only be one conclusion from the foregoing - take care of the plants correctly. Do not forget about timely watering and top dressing. At the first signs of a disease, use appropriate medications. Timely loosening will open the air to the roots, which will prevent their decay. Only in this case can you get healthy bushes with strong, green, tasty crispy fruits.
