Most often, the problem arises in case of improper care of the crop.
First of all, you need to provide the plants with normal nutrition to avoid the problem. But it is important to follow the norms, not to overdo it. Usually, voids appear with an excess of nitrogen, a deficiency of phosphorus, potassium and calcium.
Therefore, before planting cucumbers, you need to fill the holes with all the necessary means, and then add those substances that are in short supply. Root and foliar feeding are suitable for this.
Insufficient watering, as well as its uneven or irregular implementation, also leads to the problem. As a result, you can forget about a quality harvest.
It is necessary to take into account that watering should be uniform and constant. If you do not water the beds for about 3-4 days, the soil will be too dry, which means that the crop will begin to suffer.
Viral diseases and pests also affect the quality of cucumbers. Therefore, you should periodically inspect the beds.
Growing conditions are also important.
In unfavorable weather conditions, you need to take a more serious approach to caring for seedlings, otherwise you can easily lose fragrant and tasty fruits.
