Cucumbers are considered picky culture, but these plants sometimes give the gardener a lot of trouble. We will tell how to solve common problems when growing cucumbers in the greenhouse and in the open field.
Do you want cucumbers grown by you to be tasty and beautiful? Take note of these tips on how to prevent damage to the fruit.
1. Cucumbers take on an ugly shape.
The main reason for the deformation of the fruit is an imbalance in the nutrition of the plant. If the cucumber is shaped like a pear, this is a sign of potassium deficiency. You can cope with this problem in the following way: dissolve 0.5 l of ash in 10 l of water, let stand, and pour out 1 l of solution for each plant.
If cucumbers thicken near the stem, and from the opposite side, on the contrary, are narrowed, then this signals a lack of nitrogen. In this situation, you need to feed the plants with nitrogen fertilizers (according to the instructions) or organic matter (infusion of grass, solution of mullein or chicken manure).
If you have grown cucumbers "with narrow waist"(the fruit narrows in the middle), then, probably, the reason for the sharp fluctuations in air temperature. As a rule, this happens at the end of summer when growing cucumbers in the open ground. happen, cover the plants at night.
If greenhouses purchase arc shape, the cause of the deformation may be in the uneven moistening of the soil (abundant watering after a strong drought). To avoid this defect, take care of the plants correctly.
The main reason for the deformation of the fruit lies in the unfavorable conditions for growing cucumbers
2. Cucumbers bitter
The bitterness of cucumbers causes cucurbitacin. This glycoside is produced during stressful conditions for plants: droughts, sharp temperature fluctuations, etc. The most reliable way to solve this problem is to grow cucumber varieties that are genetically not bitter. But do not forget about the right care too. Properly water the plants, mulch the soil (this will keep it moist) and avoid temperature fluctuations.
To avoid bitterness when eating, cut the skin off the cucumber
3. Yellow leaves of cucumbers
If at the end of the season the leaves on the borage turn yellow, this is quite a natural process. But if the plants are stunted, yellow and dry early, it means that they do not have enough nitrogen for proper development. Feed green pets with Nitrofos: 2 tsp. Dilute fertilizers in 3 liters of water and add 200-300 ml under each bush.
Also drying out borage may lack moisture.

4. No ovaries
Fruits may not be tied for several reasons:
- Lack of pollination. If you plant bee-pollinated cucumbers in a greenhouse, insects will not be able to reach the plants. Therefore, waiting for the ovaries from such borage is meaningless. In cold and rainy weather, bees usually do not fly, so in such conditions and in unprotected soil the fruit will not be tied.
- Heat. Too high temperature also leads to the absence of fruit ovaries.
- Excess nitrogen. This element stimulates the growth of green mass to the detriment of fruiting. Therefore, fat cucumbers are blooming poorly.
- Fresh seeds. Cucumbers grown from last year’s seeds form many male flowers. It is barren as the appearance of female flowers is delayed.
To come fruiting, it is necessary to sow seeds that were stored for 2-3 years
5. Withering cucumbers
If the fruits and shoots suddenly began to fade, it is possible that the plant damaged root system. This may be due to excessive moisture or rodent invasion.
In such a situation, rake off the ground at the base of the stem and check the root collar. If it rotted and acquired a brown color, it means that the plant became ill with root rot. And if you notice dangling roots, then these are traces of pests. To save the plant, bend down the shoots and sprinkle them with soil. Soon cucumber whip rooted.
If the roots of the plant are whole, but the shoots still wither, most likely, the cucumbers are sick verticillary wilt (this viral disease is also called wilt). In this case, remove diseased plants as soon as possible, until they infect healthy ones, and spill the hole that remains after digging with a pink solution of potassium permanganate.
If the plant is affected by wilt, it will not be possible to save it.
6. Leaves form small holes.
Most often this is a sign sunburnthat occur when growing cucumbers in film greenhouses. The fact is that at night, due to the temperature difference on the film, condensate forms, during the day, drops of moisture fall on the sheet plates and burn them through, heating under the rays of the sun. To avoid this, inspect the greenhouse every morning and blot the accumulated condensate with a rag.
Do not water cucumbers when the bright sun shines.
Care for cucumbers correctly and do not forget about dressing. Then you will be able to grow an unprecedented harvest of tasty fruits.
