Fertilizing cucumbers during flowering and fruiting allows you to achieve better yield results and high quality fruits. For fertilization, ready-made mineral compositions are used, as well as folk recipes.
The value of different types of fertilizers
Timely applied fertilizers allow plants to develop faster, bloom better, form a larger number of ovaries and bear fruit longer. At the same time, it is important that the correct types of dressings are introduced at different stages of growth. It is important to know how to feed cucumbers during flowering and fruiting.
In the presence of these substances in sufficient quantities, cucumbers grow and develop.
- Nitrogenous fertilizers. If cucumbers do not bear fruit in the greenhouse or develop poorly, then this indicates a lack of nitrogenous fertilizers. Also, a narrow tip and a thick stalk will indicate a lack of substance to a cucumber. Large amounts of nitrogen are found in chicken manure, ammonium nitrate, mullein, horse manure, and compost. Ready-made nitrogen fertilizers also help cucumbers to bear fruit.
- Potassium fertilizers. Potassium is another element that cucumbers need during fruiting. With its lack, the fruits are small in size and increased rigidity. Its introduction is carried out at the beginning of the season, before the transfer of plants to a permanent place. The best results are shown by using potassium sulfate. With its use, plants grow stronger and more resistant to adverse conditions.
- Calcium fertilizers. Calcium is especially necessary for plants before flowering and the formation of the ovary. With a shortage of it, the blossoming flowers will begin to dry out and fall off. The easiest way to increase it in the soil is to feed the plants with eggshells.
- Phosphate fertilizers. Phosphorus is responsible for the development of the root system. Its introduction before planting makes the cucumbers in the open field stronger and more resistant to external factors.
For the growth and development of plants, copper, manganese, iron, magnesium are needed. For this reason, feeding of cucumbers during the fruiting period is often carried out with complex compositions.
From universal mixtures containing a large amount of essential substances, there are:
- ammonium nitrate;
- potassium nitrate.
For cucumbers to be strong, resistant to diseases, temperature extremes and bear fruit better, they must be fed regularly. This is especially true for plants in greenhouses.
You need to fertilize plants at certain stages of growth. In total, 3 or 4 dressings are made per season.
- Germination of seedlings. Top dressing during this period is necessary for the growth of strong plants and the development of the root system. In the seedling state, top dressing is applied after picking or 1-2 weeks before planting in the ground. So the plants tolerate the transition to a new place better.
- Bloom. The second feeding is done during the flowering period. Thanks to nutrients, the plant blooms better, forms a larger number of peduncles. In case of unfavorable weather conditions, fertilization helps the cucumbers to bloom.
- Ovary formation and fruiting period. The third feeding is necessary during the fruiting period of cucumbers. It can be produced during fruit setting. With fertilizers, the bushes form more ovaries and begin to bear fruit longer.
- Fruit growth period. The last feeding is done at the beginning of fruiting. It allows the formation of larger fruits with better taste characteristics.
With proper agricultural technology, not all stages of feeding for cucumbers are mandatory. Particular attention should be paid to the flowering and fruiting period.
How to feed cucumbers during flowering
The answer to the question of why cucumbers do not bloom in a greenhouse is a lack of nitrogenous fertilizers. For this reason, in greenhouses, as soon as the first bushes bloom, plants are fed with nitrogen. For plants outdoors, a mineral mixture is perfect.
The simplest recipe consists of a mixture of ammonium nitrate, potassium salt and superphosphate. The components take 30, 10 and 40 grams, respectively. The dry mixture is thoroughly mixed and dissolved in a bucket of water. The nutrient solution is applied in grooves made at a distance of 20 centimeters, parallel to the bushes.
At the beginning and end of flowering, spraying the bushes with boric acid is considered effective. Use ¼ teaspoon of acid per 10 liter bucket. Processing is carried out during the day in calm cloudy weather. On a sunny day, it is better to postpone the procedure to the evening or early morning.
How to feed cucumbers during fruiting
Fertilizing cucumbers during fruiting is associated with the active intake of nutrients from the soil. Their lack leads to poor yields and low taste characteristics of cucumbers. Of particular importance during this period is the provision of plants with potassium, nitrogen and magnesium.
To obtain the best results, fertilizers are applied in two stages:
- in the beginning - to improve the taste;
- at the end - to prolong fruiting.
When the first fruits appear, experts recommend introducing potassium or nitrophosphate into the soil. To prepare potash fertilizer, 30 grams of sulfur is diluted in a 10-liter bucket. When using nitrophoska, 1 tablespoon goes to a bucket.
For cucumbers in soil, treatment with urea is better. For 10 liters of water, 50 grams of urea is diluted. Processing is carried out in the morning. It is better to water with a solution already moistened soil.
During the fruiting period, a good result is given by feeding with ash. Use 1 cup of ground ash per bucket of water. The composition is good for both greenhouse and outdoor plants. All fertilizers are applied at intervals. Therefore, inexperienced gardeners have a question, after how many days the next feeding is allowed. In most situations, 7-14 days are kept between the application of different types of fertilizers. Complex formulations are used according to the scheme indicated on the package.
How to prolong the fruiting of cucumbers in a greenhouse
Experienced gardeners know how to increase the fruiting period of cucumbers. It turns out that you don't really need to do anything for this, it is enough to apply certain types of fertilizers at the correct periods of time. Greenhouse vegetables are best suited for a second harvest.
For a good harvest and re-flowering, cucumbers require feeding with several types of fertilizers.
- Ash solution. To prepare it, use 1 glass of ash in a bucket of water.
- Urea. The solution is prepared at the rate of 12 g of urea per 12 liters of water.
- Soda. To prepare a soda solution, you will need 1 bucket of water and 30 grams of soda.
- Infusion of rotten hay. To prepare the hay, it must be overheated for at least 2 two days.
In addition to the timely application of fertilizers, warm weather and sufficient lighting can accelerate the formation of re-ovary.
Signs of a fertilizer shortage
In order for vegetables to grow actively and have long-term fruiting, they need timely fertilization. Lack of nutrition leads to a slowdown in the growth of fruits, a decrease in the number of ovaries, and a change in the color of the leaf plate.
The fact that there is not enough fertilizer on open beds or in a greenhouse is indicated by a number of factors:
- narrowing of the tips of the fruit with thick stalks;
- reduction in the size of sheet plates;
- the presence of a whitish bloom on the fruit;
- yellowing of the leaves;
- purple color at the leaves.
One or more of these factors indicate that the plant requires a fertilizer containing nitrogen, potassium, or phosphorus.
Timely application of fertilizers allows you to improve the quality of the ovary, accelerate ripening, and get better yield indicators than when grown without fertilizing. As an experienced gardener notes: "I fed greenhouse cucumbers with chicken droppings, shells, ash and was able to achieve a double harvest." With the right choice of fertilizers, such a result is possible for everyone.
