The beds are prepared, the cucumber lashes turn green, but there are no fruits ... What if the cucumbers do not grow? The reasons can lie in many factors - from the correct preparation of seeds for sowing to meeting the requirements for growing this crop.
Often the cause of a poor harvest of cucumbers is the wrong pre-sowing seed preparation... Untreated grains go through several stages before sowing:
From the cucumber seeds collected with your own hand, you must choose the year before last. Seeds that are only 6-8 months old sprout worse, and the lashes are less productive, with a large amount barren flowers.
Even at the planning stage of the garden, they think over which varieties and hybrids of cucumbers where to plant. There is a rule that is better to adhere: do not have cucumbers pollinated by bees nearby, and parthenocarpic... In the case of such a neighborhood, it will not be possible to obtain the expected yield from both species. Parthenocarpic hybrids can be sown outdoors, but it is better not to place bee-pollinated varieties in a greenhouse.
If cucumber seeds, prepared or purchased already processed, still do not germinate, perhaps a mistake was made in the sowing process:
It happens that cucumber beds delight the eye with an abundance of greenery, under which there are very few fruits. Cucumbers do not bear fruit well if the cultivation technique is violated.
If you want to grow an early harvest of cucumbers, you need to properly transplant the young bushes. The roots of this culture get sick at the slightest injury. If the seedlings were in a common container, the cucumbers will take root for a long time or even wither away. Moving plants over 30 days of age is also unfavorable even when they are in separate cups.
There are several reasons why the culture forms few ovaries:
Gardeners control the thickening of cucumbers not only by the distance between the holes, but also by the number of plants in the nest. Usually two shoots are left per hole.
When placing holes in open ground, you should adhere to the following planting schemes for cucumbers of your choice:
A bountiful harvest is always obtained from cucumbers on trellises.
The cucumber plot is prepared in the fall, enriching the soil with humus or manure:
In early spring, they also arrange ridges for cucumbers from manure, which melts and gives off the heat necessary for the bushes.
Cucumbers almost every year are affected by the characteristic diseases... Therefore, the bed is treated without waiting for the manifestation of infection. Folk remedies for the protection of cucumbers are used weekly, and fungicides - three times, before the formation of the ovary:
Formation contributes to the emergence of new fruitful side lashes of cucumbers:
Biologically, cucumbers form new ovaries when those that have already begun to grow are harvested. Therefore, for a bountiful harvest, greens are plucked daily or every other day.
Many barren flowers create plants from the seeds of last year's harvest or those that were not warmed up before sowing, were stored in a cold room. Empty flowers are also formed when planting densely or in shade. Summer cold snaps also inhibit the formation of female-type flowers. In addition, fewer years of pollinating insects are observed on cloudy days. For a generous collection of greens, fruit formation stimulants are also used.
Cucumbers are fed from the seedling stage with complex mineral fertilizers in 10-15 days. For bushes in the fruiting phase, nutritious feeding is especially necessary. Zelentsy develop over 5-7 days, and the lash supplies them with all the necessary substances from the soil. It will be useful to feed adult plants with solutions of mullein, wood ash, yeast, herbal infusion, bread leaven. After fertilization, the bed with cucumbers is watered abundantly. Foliar dressing is also used.
Plants themselves signal a lack of nutrients.
| Signs of mineral deficiency | What element is not enough |
|---|---|
| Leaves grow smaller and pale | Nitrogen |
| Leaves become vertical | Phosphorus |
| Brown border on leaves | Potassium |
| Leaves take on a marbled color | Magnesium |
Fertilizing, you can not overfeed cucumbers with nitrogen. Then luxurious whips with several ovaries will grow.
When watering, care must be taken not to form puddles around the root section of the cucumber stem. This threatens with rotting and death of the bush. If there is no rain, water it every other day or daily, then covering the exposed root part of the lash with earth. The water warms up in the sun and is used for irrigation in the evening.
Indoors, cucumbers bear fruit better, but the culture needs to create the necessary conditions:
It is more expedient to use vertical planes, tying whips to supports and forming a cucumber bush. With this arrangement at 1 m2 plant 4-5 bushes. As soon as the first ovaries appeared, the culture is fed. Cucumbers especially need potassium and phosphorus during this period. It is more convenient to use special balanced complexes of well-known companies, modern organomineral fertilizers or long-known diammophoska, ammophoska, nitrophosphate. Organic dressings cannot be applied more than three times per season.
There is a situation when there are a lot of ovaries, but the cucumbers do not grow. The reason is most often in the fluctuations of night and day temperatures. If the thermometer reads below 12 ° C, the growth and development of the cucumber whip stops. In cloudy cool weather, airing is carried out in the warmest part of the day. Abundant watering is also suspended. Indoor humidity should not exceed 75-80%, so as not to create comfortable conditions for the spread of diseases and pests.
Observing agricultural techniques and creating comfortable conditions for the cucumbers in the greenhouse, they get a good harvest. On open plantings, pay attention to regular watering and feeding. It is important to purchase quality seeds suitable for the area.
