Planting seeds and growing cucumber seedlings are two very important stages in obtaining a large and high-quality crop. It is necessary to prepare for the works in advance, creating all the necessary conditions for the rapid growth of seedlings and young seedlings. To do this: at the beginning of autumn, select the seeds of the best varieties of cucumber, preserve them correctly, then calibrate them, temper them using various methods, and prepare them step by step for sowing.
Seeds of early early ripening varieties of cucumbers can be planted at home and in greenhouses, and seedlings of medium and late ripening can be planted directly in greenhouses or in open ground.
Basic rules and technology of cultivation
The first, and the main rule for all varieties of cucumbers - seedlings should be grown in warm and humid rooms. In greenhouses or greenhouses such conditions are provided with a film, which is necessary to cover the cucumber seedlings to keep evaporation from the soil cover. In the open ground, seedlings grown from cucumber seeds are planted in the middle of summer, when warm weather has already settled.
Pay attention to the peculiarities of growing cucumber seedlings:
Seedlings develop correctly and quickly only when the conditions of high soil moisture are observed, so make sure that the beds are watered regularly.
Spend a mandatory pinching of the plant after it gives 3 or 4 leaves. This will stimulate the rapid growth of the side shoots of cucumber (see video).
It is better to plant seedlings in well-prepared soil, with organic and chemical fertilizers introduced in advance. For cucumber, the best fertilizers are peat-rich compost added to the substrate in the fall, and mineral fertilizers with which the soil is fertilized in the spring.
When caring for still fragile and unstable seedlings from cucumber seeds, remember that the root system of this plant is located only in the upper layers of the soil (depth of 10-12 cm). Therefore, make sure that the soil does not dry out, otherwise the young shoots will not take root. For more information about the rules and technologies of growing cucumber, see the video:
How to grow strong cucumber seedlings
Regardless of whether cucumbers are grown in greenhouses or in the open field, planting seeds and growing cucumber seedlings should be carried out only taking into account all the growing technologies.
Immediately before sowing you need to properly sort the seeds, dropping them in a saline solution for a few minutes. Floated grains are not suitable for seedlings, while with those that have sunk to the bottom, you can begin to work. If this condition is met, you will provide yourself with a high probability of the germination of cucumbers.
Be sure to dry a healthy planting material at a temperature of from 50 to 550C, but not more than 4 hours, so as not to overdry. The technology of planting seeds in the ground is carried out according to certain schemes, and depends on where it is supposed to grow cucumbers and what temperature conditions will be provided for in the greenhouse or greenhouse.
After full processing of planting material, cucumber seeds are planted in a soil specially prepared for seedlings. For swelling and spitting of the seed, small planting containers or trays are selected. And at home, you can use regular disposable cups.
In order to enhance the growth of seedlings and provide them with protection from viruses and fungal infections, the soil for them should be prepared from the following components:
- Lowland peat - 3 parts;
- Korovyak 0 0.5 parts;
- Sawdust - 1 part.
The mixture will give the result if all the conditions of its preparation are fully met, the main of which is thorough mixing of the components. Then 500 g of potassium, 100 g of nitrogen and 3 kg of phosphorus are added to the substrate (data are given per 1 m3 ground mix).Attention! Remember that in order to grow strong seedlings from seeds, the humidity in the room must be maintained at 70% (not lower).
In the process of growth, pay attention to the fact that the distance between cucumber seedlings on the soil surface does not exceed 5-7 cm. Immediately remove low-growing plants. A week before planting, be sure to adapt the seedlings to seasonal air temperatures. To do this, every day, increase the time of airing and hardening. Such conditions of detention will allow in 5-6 days to take the shoots to the street.
The day before planting, feed the cucumber with mineral fertilizer. You can prepare it by mixing superphosphate, potassium sulphate and ammonium nitrate at the rate of 40:30:10 g to a bucket of water. Strain the solution through gauze. In order for the plant to properly receive all the substances necessary for it, after treatment with fertilizers, the stems and leaves should be washed with running water. This will help the seedlings that have not yet become stronger avoid burns.
If there is an opportunity to additionally cover seedlings from cucumber seeds with a film - plant them in open ground in the beginning or in the middle of May. If this is not possible, focus on the middle or the end of June, when the likelihood of frost on the ground will be minimized.

How to grow seedlings in the open field
The middle of June is the optimal calendar terms for placing cucumber seedlings in open ground. Plants should be planted in the prepared substrate in the second half of the day, a few days after the rain, but only when the weather is consistently warm and windless.
Before work on the bed, ridges are equipped (see video). Cucumber seedlings are determined from the south side of the ridge and lowered into the wells to a depth of the first cotyledon. Immediately after planting the seedlings, the beds must be watered, the next watering the young plant will be needed only in 3-4 days. Water for watering cucumbers should be well settled, and its temperature should be at least 22-250WITH.
Attention! After the second watering, as the soil settles, it is necessary to pour a little sod land with humus to each seedling.
Note that young cucumber seedlings require constant feeding. The power and speed of growth, the duration of the growing season of cucumbers, the period of full ripening and, of course, the yield depend on how correctly and regularly you will fertilize the plant.
The technology for preparing a solution that has proven itself in the cultivation of any cucumber varieties is as follows:
- In a volume tank stir 5 grams of ammonium nitrate and 10 liters of purified water;
- Add 4-5 grams of potassium chloride;
- We mix 10-12 grams of superphosphate.
Such a mixture for fertilizing cucumbers experienced gardeners called "talker". It is ideal for all garden crops, except root crops. Cucumbers, constantly receiving such top dressing, have dense and strong stems, and seedlings have bright dark green fruits and leaves. In addition, the development time of seedlings from seeds, ovaries, and as a final result, yields increase.

Cucumber seedlings grown in greenhouses
As a rule, seedling of cucumbers of early and early ripening varieties is grown in greenhouse conditions. The timing of planting a cucumber is the beginning of May, but if you have the opportunity to cover the shoots with an additional film cover, you can start a transplant at the beginning or middle of April. In this case, the temperature in the greenhouse should not fall below 20-220C, and the soil is arranged under a dung-steam bed.
If you did not update the substrate in the greenhouse, add some chopped straw or sawdust and about 15-20 grams of ammonium nitrate to the cucumber seedlings, and then dig up the soil.
Attention! Cucumbers in the greenhouse are planted in a single line. On the bed between the seedlings aged 30 cm, between the beds - 100-120 cm.
In the hole, a depth of 8-10 cm placed cucumber seedlings so that the ground does not cover the stem of the seedlings. 2-3 days after planting the plant must be tied up. To do this, parallel to the row at a height of 20 cm, the wire is tensioned or a strong cord. To him and tied saplings.
If the rows in the greenhouse are not equipped with supports for the branching of cucumbers, such ropes should be stretched with a step of 20-30 cm to a height of 2 meters. Do this in advance, so that by spending work in the process of growth you will not accidentally injure the seedlings.
Properly care for cucumber seedlings in a greenhouse should be as follows:
- Provides moderate watering, which is carried out only on warm sunny days;
- When cucumber 5 and 6 appear on the leaflet, be sure to feed it with a solution prepared from 10 grams of urea per 10 liters of water. Such food is necessary for seedlings after long overcast or rainy weather;
- Cucumber - one of the few plants that in a greenhouse or greenhouse require regular airing of air.
As a rule, self-pollinating varieties of cucumber hybrids are planted in greenhouses and greenhouses, so the technology of cultivation and care must fully comply with the instructions attached to the seeds you bought.
