If the stems are thickened culture next to the stem, then it is a consequence of nitrogen deficiency. In such a case, necessary to use nitrogen or organic fertilizing agents (mullein, herbal tincture or bird droppings).
If the cucumber fruit purchased arcuate shape, it may be due to uneven watering the soil. To prevent such a defect, it is necessary to closely monitor the watering regime.
The bitterness of the fruits of this culture provokes kukurbitatsin. This substance belongs to a class of glycosides and synthesized, when the plant is under stress due to temperature surges, drought, etc. To avoid this problem, it is desirable to grow varieties that do not have a genetic propensity to bitterness.
If at the end of the growing season on the plant foliage has turned yellow, then this process is natural. However, if the cucumbers grow very slowly dry out ahead of time and are covered with yellow spots, then this is a consequence of lack of nitrogen. To solve this problem you need 3 liters of water dissolve 2 tsp nitrophosphate. Under one bush need poured 200-300 ml of solution.
Sometimes on cucumbers do not form ovaries. This may be due to such reasons:
- No pollination. If you put pcheloopyljaemogo variety in the greenhouse, then the beneficial insects will not be able to reach it.
- Hot weather.
- Increased concentration of nitrogen. This substance accelerates the development of the greenery, and a negative impact on fruiting.

In this case, you need otgresti soil near the stem and root neck visually inspect for damage. If there are signs of rot or dark spots, then the culture was struck by the disease. For the salvation of cucumbers need to bend shoots and fill them with earth. Within a few days, they take root.
If there are no problems with the root system and the plant parts wither, then it may be a sign of the development of Verticillium wilt. To combat this viral pathology is necessary to eliminate the affected part, but the rest of the hole must be filled with a solution of manganese.
If the cucumber sheets having small holes, it may be a sign of sunburn. This is due to the fact that during the night because of the temperature difference on polyethylene condensate formed in the greenhouse. Day of this moisture falls on the sheets and leave them for burns, working on the principle of the magnifying glass. To prevent this, you need every day to inspect the greenhouse construction and promptly remove the accumulated water droplets.
