When and what fertilizers to use for feeding cucumbers in the greenhouse


How to feed the cucumbers in the greenhouse so that the vegetables in the end are tasty, crispy and enriched with vitamins? To do this, you need to feed them properly 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. Most importantly, you need to choose a certain variety that would have enough space on the windowsill.

Another important condition is the correct soil. 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 onset of the fruiting stage, it is necessary to carry out three dressings:

  1. Two weeks after germination of seeds (superphosphate and urea are dissolved in 10 liters of water).
  2. Another 10 days after the previous feeding.
  3. The latter is carried out after another 10 days (ash and nitrophoska are suitable).

As soon as the fruiting period begins, fertilizing indoor cucumbers should be accompanied by the introduction of wood ash. How often do you need to recharge? Then, every two weeks, standard compound fertilizers purchased from the store are used.

Phased feeding

Now, in almost every territory of the cottage, you can find a polycarbonate greenhouse. This material is suitable for growing many crops and makes plant maintenance easy. Polycarbonate does not block daylight, keeps you warm and is easy to collect. After installing it, another question arises: how can you fertilize cucumbers in a greenhouse?

Fertilizing cucumbers in a polycarbonate greenhouse should be based on 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 area. Fertilizers for cucumbers in the greenhouse begin to be prepared in October, when the site is dug up and covered with manure.

If fertilization was not possible in the fall, then in the spring fresh manure cannot be used, since the weak roots of the seedlings are burned. Humus or peat can be used before transplanting. Spring mineral dressing may contain urea, superphosphate and potassium chloride. When planting cucumbers, fertilizers 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 at least three feedings, but the schedule may vary and include more feeds. Just not more than once every two weeks.

The scheme for feeding cucumbers in a greenhouse can be represented approximately like this:

  1. The first feeding of cucumbers after planting in the greenhouse should be before flowering, when the first few leaves have appeared. You can use organic or mineral fertilizers, but always with a nitrogen content.
  2. 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.
  3. When the vegetable is actively bearing fruit, it will be time to apply the next top dressing, approximately in another two weeks.
  4. Additionally, during fruiting in the greenhouse, a fourth feeding is carried out after another 12 days. Cucumbers in a greenhouse are fed with a composition with phosphorus and potassium. Mineral dressing of superphosphate, ammonium nitrate and potassium sulfate at this time is taken in slightly larger proportions.

How to feed cucumber seedlings immediately after planting in a greenhouse? You can water the cucumbers with superphosphate, mullein, or ammonium nitrate. Finished fertilizers that are of the best quality: Crystallin A, Potassium sulfate, Humated fertilizers.

Calcium is essential for fruit growth and healthy development. With its deficiency, there is a high probability of the beginning of the decay process, while the ovaries will fall off, and growth will stop. The fruits turn yellow, change shape, and taste bitter. 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.

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

Top dressing is especially important during flowering and fruiting of a cucumber. The crop will depend on feeding. You can make a solution for watering at the root, for spraying leaves and dry dusting of plants. It is allowed to add both manure, herbal infusion, and urea, superphosphate.

Possible problems

If the cucumbers wither and do not bear fruit in the greenhouse, what to do in this case? Watering and feeding cucumbers should be carried out according to the rules and in moderation. Even taking good care of your vegetables does not rule out problems. The fact that cucumbers grow poorly and lack nutrients 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 is an excess of potassium;
  • iron deficiency leads to the fact that vegetables grow poorly, the 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;
  • the lack of nitrogen is indicated by curling of the fruit 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 in the store:

  1. Diammofosk is available in the form of granules that dissolve in water. Water the soil between the beds before flowering. Due to the nitrogen content, the growth of cucumbers is accelerated, and phosphates help to gain strength. Potassium helps to increase the yield.
  2. Among the best fertilizers, Ammofoska is distinguished, which contains all the necessary components. It is recommended to buy for those who have an arid planting zone.
  3. Sulfuric Nitrofoska 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 uniform. Care should be based on soil composition, greenhouse material, planting and growing weather conditions. Not only a deficiency of some nutrients, but also an excess of them can lead to a poor harvest or the death of the plant.

Types of food

When feeding cucumbers in the greenhouse, what fertilizers should be used and when? Natural solutions often contain manure, grasses, bird droppings, ash, and other ingredients that can help save money. Feeding cucumbers in a greenhouse with folk remedies can be carried out with the following compositions:

  1. Mullein, nitrophoska are diluted in water, wood ash, boric acid and manganese sulfate are added. Cucumbers may need this composition in the greenhouse during the beginning of flowering and the formation of ovaries.
  2. Vegetables are fed with wood ash throughout the entire growth period with an interval of 9 days. Can be used dry or infused. For the 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.
  3. A popular recipe with manure, chicken droppings and slurry. Each component must be pre-diluted with water.
  4. Feeding cucumbers in a greenhouse is not complete without fresh or rotted chicken droppings. The over-matured composition is diluted with water 1:10, fresh droppings are diluted with water in a ratio of 1:20. Before processing the soil, you need to water the cucumbers with plain water. Only the space between the beds can be watered with a solution with droppings.
  5. The herb infusion is used for watering 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 one nettle, I also add quinoa and plantain." The herbs are crushed, poured with water and insisted for three days.
  6. Greenhouse feeding of cucumbers is not complete without eggshell, 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 insisted for three days.
  7. You can feed the plant with onion peel infusion. Add 200 g of onion husks 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 a similar solution is calculated.
  8. With your own hands, you can make yeast feeding, which is watered with 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 yeast in water and leave for a day to ferment. You need to add nutrients under the base.

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

  1. The first feeding of cucumbers in the greenhouse, when the first two leaves bloom, may include urea and superphosphate.
  2. During the second feeding, water the plants with a solution of potassium and ammonium nitrate, superphosphate.
  3. 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 your cucumbers in the greenhouse. Useful ingredients are distributed throughout the plant not only during root feeding.

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

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

Fertilizer for cucumbers must be chosen correctly. It is not necessary to 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 encountered. Only in this case you can harvest a good harvest, which will delight you with its quantity and quality.
