Feeding cucumbers in a greenhouse: what fertilizers and when to use correctly

How to feed cucumbers in a greenhouse so that the vegetables in the end are tasty, crispy and enriched with vitamins? To do this, you need to properly feed them throughout their growth. Greenhouse soil does not always have the necessary supply of nutrients, especially little nitrogen. During the introduction of additional nutrition, the stage of development of the cucumber, the appearance and condition of the soil are taken into account.

Home option

To grow cucumbers at home, several conditions must be met. The most important thing is to choose a certain variety that would have enough space on the windowsill.

Another important condition is the right ground. It should contain components such as humus, sawdust, peat. Nitrophoska (30 g), wood ash (200 g), urea (15 g) can serve as the first fertilizer. When sowing, it is not recommended to use fertilizer.

Before the fruiting stage, three top dressings must be carried out:

Two weeks after seed germination (superphosphate and urea are dissolved in 10 liters of water).
Another 10 days after the previous feeding.
The last one is carried out after another 10 days (ash and nitrophoska are suitable).

As soon as the fruiting period begins, fertilizer indoor cucumbers should be accompanied by the introduction of wood ash. How often do you need to re-feed? Then, every two weeks, use standard complex fertilizers bought at the store.

Phased recharge

Now you can find a polycarbonate greenhouse in almost every country house. This material is suitable for growing many crops and makes plant care easy. Polycarbonate does not interfere with the penetration of daylight, retains heat and is easy to assemble. After installing it, another question arises: how can you fertilize cucumbers in a greenhouse?

Feeding cucumbers in a polycarbonate greenhouse should basically have potassium, phosphorus and nitrogen substances. During the growth period, the vegetable needs nitrogen, especially when shoots and ovaries are formed. During fruiting, the need for potassium and phosphorus nutrition increases.

How to properly feed cucumbers in a greenhouse, starting with tillage? To get a rich harvest, you need to prepare the soil. It is necessary to plant cucumber seeds in a well-lit place. Fertilizers for cucumbers in the greenhouse begin to be prepared as early as October, when the site is dug up and covered with manure.

If it was not possible to apply fertilizer in autumn, fresh manure cannot be used in spring, as weak roots of seedlings are burned. Before transplanting, you can use humus or peat. Spring mineral dressing may contain urea, superphosphate and potassium chloride. When planting cucumbers, fertilizer should not be applied immediately, but only after a few days.

How to feed cucumbers in a greenhouse depends on the stage of development. Caring for vegetables during development requires a minimum of three feedings, but the schedule may change to include more feedings. Only no more than once every two weeks.

The scheme for feeding cucumbers in a greenhouse can be represented approximately as follows:

The first dressing of cucumbers after planting in the greenhouse should be before flowering, when the first few leaves appeared. You can use organic or mineral fertilizers, but be sure to contain nitrogen.
The second feeding coincides with the appearance of color and the formation of ovaries. This is about 2 weeks after the last feeding. The fertilizer should already contain less nitrogen, but enough potassium. As a mineral fertilizer after planting, the use of fertilizer obtained from superphosphate, ammonium nitrate and potassium sulfate is suitable. All components are diluted with 10 liters of water.
When the vegetable is actively bearing fruit, it will be the turn to make the next dressing, in about another two weeks.
Additionally, during fruiting in the greenhouse, after another 12 days, the fourth feeding is carried out. Cucumbers in a greenhouse are fed with a composition with phosphorus and potassium. Mineral top dressing from superphosphate, ammonium nitrate and potassium sulfate at this time is taken in slightly large proportions.

How to feed seedlings of cucumbers immediately after planting in a greenhouse? You can pour cucumbers with superphosphate, mullein or ammonium nitrate. Names of ready-made fertilizers that are of better quality: Crystallin A, Potassium sulfate, Humatized fertilizers.

Calcium is essential for fruit growth and he althy development. With its deficiency, there is a high probability of the onset of the process of decay, while the ovaries will fall off, and growth will stop. The fruits turn yellow, change shape, and become bitter in taste. Cucumbers for the second time can be processed with one of the recipes based on eggshells or calcium nitrate 0.2%. Top dressing for cucumbers is applied before flowering.

Feeding cucumbers during the fruiting period should contain potassium, nitrogen and magnesium, and potassium should be more than nitrogen. The best care at this time is accompanied by a fertilizer in the form of potassium nitrate, which removes excess bitterness and activates the growth of fruits.

Feeding during flowering and fruiting cucumbers is especially important. The harvest will depend on the feeding. You can make a solution for watering under the root, for spraying leaves and dry dusting plants. It is allowed to apply both manure, herbal infusion, and urea, superphosphate.

Possible problems

If cucumbers wither and do not bear fruit in a greenhouse, what to do in this case? Watering and fertilizing cucumbers should be carried out according to the rules and in moderation. Even good care of vegetables does not exclude the appearance of problems. The fact that cucumbers do not grow well and they lack nutritional components can be recognized by their appearance:

if yellow spots appear on the leaves, it is quite possible that there is not enough magnesium or there was an excess of potassium;
iron deficiency causes vegetables to grow poorly, leaves turn white;
if the fruits become uneven, resemble the shape of a pear, then you need to make up for the lack of potassium;
Nitrogen deficiency is indicated by twisting of fruits and thickening of the base;
when cucumbers grow slowly in a greenhouse, and pale spots appear on young leaves, it means that there is not enough calcium - the fruits are small and tasteless.

If the problem cannot be determined by the appearance of the cucumbers, then complex fertilizers are used, which can be bought at the store:

Diammofoska is produced in the form of granules that dissolve in water. Water the soil between the beds in the period before flowering. Due to the nitrogen content, the growth of cucumbers is accelerated, and phosphates help to gain strength. Potassium improves yields.
Ammofoska, which contains all the necessary components, is distinguished among the best fertilizers. Recommend to buy for those who have a dry planting zone.
Sulfur Nitrophoska is produced in granules. Sulfur is an additional component. The composition not only nourishes the plant, but is also able to repel insect pests.

In a greenhouse, feeding of all cultivated plants, including cucumbers, cannot be the same.Care should be based on the composition of the soil, greenhouse material, weather conditions at planting and during growth. Not only a deficiency of some nutrients, but also their overabundance can lead to a poor harvest or plant death.

Meals

When feeding cucumbers in a greenhouse, what fertilizers and when to use? Natural solutions often contain manure, herbs, bird droppings, ashes, and other ingredients that can save you money. Top dressing of cucumbers in the greenhouse with folk remedies can be carried out with the following compositions:

Mullein, nitrophoska are diluted in water, wood ash, boric acid and manganese sulphate are added. Cucumbers in the greenhouse may need this composition during the beginning of flowering and the formation of ovaries.
Wood ash is fed to vegetables throughout their growth with an interval of 9 days. Can be used dry or infused.For infusion, about 200 g of ash is useful, which is poured with warm water and left to infuse for two days. Before watering, the solution is diluted in 10 liters of water.
A popular recipe with manure, chicken manure and slurry. Each component should be pre-diluted with water.
Feeding cucumbers in a greenhouse is not complete without fresh or rotted chicken manure. The rotted composition is diluted with water 1:10, fresh litter is diluted with water in a ratio of 1:20. Before tilling the soil, you need to water the cucumbers with plain water. You can only water the space between the beds with a solution with litter.
Infusion of grass is used to water the beds. Nettle is considered the most useful for its high content of trace elements. Summer residents note the benefits of such dressings: “I use the infusion not only from nettle alone, I additionally add quinoa and plantain.” Herbs are crushed, poured with water and insisted for three days.
Greenhouse feeding of cucumbers is not complete without egg shells, as it contains many trace elements. You can simply crush the shell and sprinkle the beds, or you can make a tincture. The shells of several eggs are crushed, poured with water and infused for three days.
You can feed the plant with an infusion of onion peel. 200 g of onion peel are added to a bucket of water and put on fire. As soon as the water boils, remove from the stove and leave to infuse for 5 hours. For each root, 1 liter of such a solution is calculated.
With your own hands you can make yeast top dressing, which is watered by flowering plants. The composition will compensate for the deficiency of phosphorus, potassium, vitamins and minerals, as a result, the yield and quality of taste increase. You can dissolve the yeast in water and leave for a day to ferment. You need to bring nutrients under the base.

For cucumbers in the greenhouse, mineral top dressing can also be chosen:

The first dressing of cucumbers in the greenhouse, when the first two leaves bloom, may include urea and superphosphate.
During the second feeding, water the plants with a solution of potassium and ammonium nitrate, superphosphate.
During the period when the fruits appear, it is recommended to water the cucumber beds with potassium nitrate or urea diluted in water.

There are two ways to feed cucumbers in a greenhouse. Useful ingredients are distributed throughout the plant, not only during root feeding.

It is useful to use foliar top dressing. A few recipes suitable for spraying the leafy parts of cucumbers:

dilute superphosphate, sulfuric manganese, potassium nitric acid, boric acid and zinc sulfate in water;
useful to use a urea-based solution;
composition of potassium permanganate and boric acid is considered effective.

Fertilizer for cucumbers must be chosen correctly. You should not water and cultivate the soil with any compounds that are at hand. Be sure to take into account the stages of growth and the problems that have arisen. Only in this case can you harvest a good crop that will please you with its quantity and quality.
