First, consider what elements are needed for cucumbers:
Before sowing, it is advisable to warm the cucumber seeds in a hot saline solution for 3 hours. When planting seeds in open ground, they need to go through a hardening procedure. After processing, the seeds are placed in a refrigerator for 3 days and then germinated.
We recommend that you read an article on how to plant tomatoes for seedlings, you can find it here https://tytdacha.ru/sad-i-ogorod/ovoshhi/kak-sazhat-pomidory-na-rassadu/
You need to know that cucumbers do not always tolerate transplanting well, therefore, when growing a plant by the seedling method, one or two seeds are laid out in a separate pot or glass. The composition of the soil for seedlings must include peat, sod land, sawdust and humus. If two shoots sprout in the pots, the weaker one should be removed. Planting seedlings in open ground is carried out after the appearance of several dark green leaves on the bush. This usually occurs 25 days after sowing.
With good growth of cucumber seedlings both indoors and outdoors, you can take your time with the first feeding. Fertilizers require weak and lifeless sprouts. The main rule of the first feeding: cucumbers must receive a sufficient amount of nitrogen.
Top dressing is carried out when the first leaf is formed in the plant. Cow dung or chicken droppings are poured with water, stirred and left in a dark place for fermentation. Ammonium nitrate, superphosphate, potassium sulfate are added to the resulting solution for better efficiency. The plant is fertilized a week after the preparation of the solution. This is done in the morning, after abundant watering of the soil. The mixture is introduced into the grooves in close proximity to the plant.
Weak growing seedlings in the greenhouse are fed every 10 days. They use organic and later mineral fertilizers.
When inflorescences and fruits appear, cucumbers need fertilizing based on magnesium and potassium. In addition to chicken manure and cow manure, potash fertilizers and mineral fertilizers are used. During active ripening of fruits, seedlings are sprayed with an aqueous mixture, which includes boric acid.
It is a valuable complex fertilizer in terms of the amount of useful microelements it contains. The beds can be simply sprinkled with dry ash, or even better, water the plants with a solution prepared on its basis. For its preparation, the ash is stirred in a large amount of water.
This fertilizer is literally under everyone's feet. For its preparation, fresh grass, weeds, tops of plants, fallen fruits are used. For fermentation, the compost is placed in a barrel, filling it by two-thirds, and topped up with water. The barrel must be covered with a lid. In warm weather, the liquid compost will be ready after a few days. The resulting mixture can be fed not only cucumbers, but also other plants in the beds.
There are ready-made yeast-based products on sale. But you can prepare such a top dressing yourself. A bag of dry yeast is diluted with water with the addition of a few tablespoons of sugar for better fermentation. Such feeding should not be carried out often, it is carried out a maximum of twice per season. After it, the cucumbers grow well.
It is important to remember that when choosing any top dressing, it is better to make small doses, as well as alternate them with each other.
Having set yourself the task of growing delicious cucumbers and even in large quantities, you cannot follow the principle "the more the better." With sufficient air humidity and timely watering, cucumbers will actively bear fruit even with infrequent feeding (for example, 2 per season). An excess of applied fertilizers, non-compliance with the norms may even turn out to be detrimental.

Cucumbers will grow well and give a large harvest only if the soil is fertile. Moreover, it is better to plant them the next year after mineral, and especially organic fertilizers have been introduced into the soil. Manure must be used as an organic fertilizer, they do not like humus and can stop growing and dry up immediately after the first fruits ripen and no, even the most caring care will help them.
Organic matter as fertilizer is most suitable, since the root system of cucumbers is superficial and its assimilating properties are not very good, but at the same time, in a short growing season, the plant needs to create a multiple leaf system and give many fruits. Therefore, fertilizers are necessary so that they are absorbed by the plant easily and in sufficient quantities. With such sensitivity to soil fertility and fertilization, the soil must be prepared in advance. Two thirds of the total amount of necessary fertilizers must be applied for digging, the rest - before planting while loosening the soil or simultaneously with planting seedlings.
Seedlings grown on a windowsill require good nutrition. Only in this case, the plant will actively develop, and subsequently bring good harvests throughout the summer season.
Important! From the very beginning, he needs to provide a nutritional complex in the form of mineral elements and organics.
There are several basic nutrients that need to be given to a plant for healthy growth and full fruiting.
If there is a lack of any nutrients, the plant has corresponding signs that can be easily noticed:
Ash - an excellent organic fertilizer, the exact chemical composition of which is difficult to determine in advance. The fact is that it depends on the type and age of the burned plant. However, the ash invariably contains calcium, which is so necessary for the growth of cucumbers.
Ash is introduced only 5-6 times during the growth period of cucumbers. The first time this is done at the very beginning of the formation of the plant, when 2-3 leaves appear on the stem, the next time - at the beginning of flowering, and only then, as the fruits grow, with intervals of 14 days between dressings.
Ash can be used in two forms:
Sprinkle dry ash on the soil before watering the plants. To prepare the ash infusion, pour 10 tbsp. ash 5 liters of water and leave for 8-10 days, stirring the composition regularly.
It is very important that the ash is woody, free from debris or plastic
Before planting plants, it is necessary to prepare the soil in advance (2-3 weeks). This preparation should start with weed control, because cucumber does not tolerate contaminated soils. Weeds can be controlled both with the help of herbicides (Roundup, Tornado, Lontrel), and mechanically, removing the roots and rhizomes of weeds during the digging of the soil.
Then, for each square meter of soil, 8-15 kg of enriched peat substrate must be applied as an organic fertilizer (for example, "Our dacha Garden land", "Our dacha Vegetable bed", "4 seasons Harvest bed") - to increase soil fertility and improve physical and mechanical properties of the soil.
Why such a fertilizer? Fresh manure for application under cucumbers is not suitable, because can cause root burns and nitrate nitrogen poisoning. To ensure a full-fledged balanced diet, it is also necessary to add 40-50 g of superphosphate and 30 g of potassium sulfate for each meter for digging.
After applying and digging the soil to destroy weeds, it is necessary to carry out 2-3 loosening.
As a rule, seedlings of early and early ripening varieties of cucumbers are grown in greenhouse conditions. The dates for planting a cucumber are early May, but if you have the opportunity to cover the seedlings with an additional film blanket, you can start transplanting in early or mid-April. In this case, the temperature in the greenhouse should not fall below 20-22 0 С, and the soil is arranged under a manure-steam bed.
If you did not renew the substrate in the greenhouse, add a little chopped straw or sawdust and about 15-20 grams of ammonium nitrate to the places where the cucumber seedlings are planted, and then dig up the soil.
Cucumber seedlings are placed in holes 8-10 cm deep so that the soil does not cover the seedling stem. 2-3 days after planting, the plant must be tied up. To do this, a wire or a strong cord is pulled parallel to the row at a height of 20 cm. Seedlings are tied to it.
If the rows in the greenhouse are not equipped with supports for branching cucumbers, such ropes must be pulled in 20-30 cm increments to a height of 2 meters. Do this in advance so that you do not accidentally injure the seedlings while carrying out work during the growth process.
It is necessary to properly care for the seedlings of cucumbers in the greenhouse according to the following scheme:
As a rule, self-pollinating varieties of cucumber hybrids are planted in greenhouses and greenhouses, therefore, the cultivation and care technology must fully comply with the instructions attached to the seeds you purchased.
