Caring for cucumbers in a polycarbonate greenhouse does not require special knowledge and skills of the gardener. Such a greenhouse option is the most suitable for solving problems of growing plants. The construction will allow to obtain a high yield of cucumbers due to its design and optimal temperature conditions. Vegetable belongs to the heat-loving plants, he does not like a sharp temperature drop. Polycarbonate also retains heat well in the daytime as well as at night.
How to water and tie cucumbers
After 3-4 leaves appear on the plant, it is transplanted into the greenhouse. From this point on it is necessary to carefully care for the fruits. Cucumber absorbs a lot of moisture, so it requires proper and regular watering.
The main rule to remember is to use room temperature water. Cold water adversely affects plant growth and development. All processes slow down.
With systematic improper watering on leaflets can be a variety of diseases. Water should not fall on top of the plant. Watering is carried out strictly under the root. Otherwise, the spread of disease is guaranteed. To obtain a high yield, it is necessary to maintain a suitable moisture content in a polycarbonate greenhouse — no more than 90%. This will require up to 5 liters of water under each bush.
The peculiarity of the structure of the plant prompted the person how best to tie cucumbers.
Gardeners are advised to install trellis, designed specifically for this purpose. They allow you to grow fruits in an upright position.
In the greenhouse there is more space, and the plant develops better. Sometimes it reaches 2 m in height. The design of the trellis may be different. Their main task is to create support for cucumbers and facilitate harvesting. Also important factor is the preservation of the integrity of the plant during the care. If the fruits ripen on the ground, they are inconvenient to pick and water.
The importance of weeding and feeding
Any living organism must breathe. No exception and cucumbers. The owner of the greenhouse is obliged to regularly weed the plant and loosen the ground. However, this should be done very carefully, because the roots of cucumbers are rather fragile and vulnerable. Any wrong movement - and part of the bush with color and young shoots is broken. We should not forget about the systematic airing of the polycarbonate greenhouse. In warm or hot weather, its vents for the day should be left open.
The plant constantly needs useful substances that would give it the power to grow and produce healthy fruits. It is necessary to feed cucumbers at least 5 times a season. An essential component of their nutrition are organic materials:
Without them, cucumbers can go to wasteland. Fertilizer is added to water in the ratio of 1 l of organic matter and 10 l of water. If you do not respect the proportions, you can harm the plant. For example, the leaves begin to turn yellow from a large amount of vitamins. In the first days of landing in the ground, it is desirable to introduce nitrogen compounds. Such fertilizers include phosphorus. Nitrogen-potassium substances are added during fruiting. Sometimes gardeners resort to the use of minerals. In a bucket of water, 5 g of saltpeter, 5 g of potassium salt and 10 g of superphosphate are mixed. All fertilizers are applied only at the root.
How to deal with pests and diseases of cucumbers
Care for cultivated plants should be carefully, systematically checking the condition of their leaves, developing fruits and flowers. Otherwise, you can not notice the dangerous infections, among which the most dangerous:
- root rot;
- powdery mildew;
- gray rot;
- brown spot.
The most common disease is powdery mildew. If white leaves are visible on the leaves, it means that the plant has become infected.Attention! To save cucumbers, you need to take 1 kg of manure, 1 tbsp. urea and dilute them in a bucket. Spray the entire surface of the plant in the morning.
No less dangerous to defeat cucumber root rot.
The causes of its occurrence are characterized by temperature changes in the greenhouse, irrigation with cold water, planting seedlings each year in the same soil.
To determine the presence of the disease is very simple. On the stem are noticeable:
- color change from natural green to yellow.
To combat the disease in 0.5 liters of water is diluted with 1 tsp. copper sulfate, copper oxychloride, 3 tbsp. chalk or lime. The resulting mixture is applied to damaged areas.
Gray rot occurs on the leaves, stalks of cucumbers. Mostly infection occurs due to improper airing of the greenhouse, cold watering. To get rid of the disease, should be mixed with 1 tsp. copper sulphate 1 glass ash.
It is important to remember that after processing, it is necessary to remove all infected shoots and burn them. If brown spot is found on the plant, which is manifested by reddish formations with liquid, it is necessary to immediately stop watering for 5 days. At this time, conduct rapid resuscitation borage. Otherwise he will die. In a bucket of water, add 30 g of foundation or bordeaux substance.
In addition to diseases, plants can be damaged by insects.
One of them is the greenhouse whitefly. Sitting on the leaves, it releases a substance that allows the development of harmful soot fungi.
To prevent whitefly, weed should be removed in time, properly watered, and special glue insect traps should be installed. Only careful care and care gardener will bring a good harvest.
Timely and proper prevention of diseases, the emergence of pests will increase its quality and duration of fruiting.
