Caring for cucumbers in a polycarbonate greenhouse does not require special knowledge and skills from the gardener. This greenhouse option is the most suitable for solving plant growing problems. The structure will allow you to get a high yield of cucumbers due to its design and optimal temperature conditions. The vegetable is a heat-loving plant; it does not like sudden temperature changes. Polycarbonate perfectly retains heat both during the day and at night.
How to water and tie cucumbers
After 3-4 leaves appear on the plant, it is transplanted into a greenhouse. From this moment 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 water at room temperature. Cold water negatively affects the growth and development of the plant. All processes slow down.
With systematic improper watering, various diseases can spread on the leaves. Water should not get on the top of the plant. Watering is carried out strictly at the root. Otherwise, the spread of diseases is guaranteed. To get a high yield, it is necessary to maintain appropriate humidity in the polycarbonate greenhouse - no more than 90%.This will require up to 5 liters of water for each bush.
The peculiarity of the structure of the plant told the person how best to tie cucumbers.
Gardeners advise installing trellises designed specifically for these purposes. They allow you to grow fruits in a vertical position.
There is more space in the greenhouse, and the plant develops better. Sometimes it reaches 2 m in height. The design of the trellises may be different. Their main task is to create support for cucumbers and facilitate harvesting. Also an important factor is maintaining the integrity of the plant during care. If the fruits ripen on the ground, they are inconvenient to pick and water.
The importance of weeding and fertilizing
Any living organism must breathe. Cucumbers are no exception. The owner of the greenhouse is obliged to regularly weed the plant and loosen the soil. However, this must be done very carefully, because the roots of cucumbers are quite fragile and vulnerable. Any wrong movement and part of the bush with flowers and young shoots is broken. We should not forget about systematic ventilation of the polycarbonate greenhouse. In warm or hot weather, its windows should be left open during the day.
The plant constantly needs nutrients that would give it the strength to grow and produce healthy fruits. Feed cucumbers necessary at least 5 times a season. Organic materials are a mandatory component of their diet:
- manure;
- compost;
- ash.
Without them, cucumbers may become barren. Fertilizer is added to water in a ratio of 1 liter of organic matter and 10 liters of water. If you do not comply with the proportions, you can harm the plant. For example, leaves begin to turn yellow from a large amount of vitamins. In the first days of planting, it is advisable to add nitrogen compounds to the soil. Phosphorus is one of these fertilizers.Nitrogen-potassium substances are added during fruiting. Sometimes gardeners resort to using minerals. Mix 5 g of saltpeter, 5 g of potassium salt and 10 g of superphosphate in a bucket of water. All fertilizers are applied only at the roots.
How to deal with pests and diseases of cucumbers
Cultivated plants should be cared for carefully, systematically checking the condition of their leaves, developing fruits, and flowers. Otherwise, you may not notice dangerous infections, among which the most dangerous are:
- root rot;
- powdery mildew;
- gray rot;
- brown spot.
The most common disease is powdery mildew. If a white coating is noticeable on the leaves, it means that the plant has become infected.
No less dangerous is the defeat of cucumbers by root rot.
The reasons for its occurrence are characterized by temperature changes in the greenhouse, watering with cold water, and planting seedlings every year in the same soil.
Determining the presence of the disease is very simple. Noticeable on the stem:
- cracking;
- rot;
- color change from natural green to yellow.
To combat the disease, dilute 1 tsp in 0.5 liters of water. copper sulfate, copper oxychloride, 3 tbsp. chalk or lime. The resulting mixture is applied to the damaged areas.
Gray rot occurs on the leaves and stems of cucumbers. Infection mainly occurs due to improper ventilation of the greenhouse and cold watering. To get rid of the disease, mix with 1 tsp. copper sulfate 1 cup ash.
It is important to remember that after treatment you need to remove all infected shoots and burn them.If brown spotting is detected on the plant, which manifests itself as reddish formations with liquid, you must immediately stop watering for 5 days. At this time, rapid resuscitation of the borage plant is carried out. Otherwise he will die. Add 30 g to a bucket of water foundationazole or Bordeaux substance.
In addition to diseases, insects can harm plants.
One of them is the greenhouse whitefly. Sitting on the leaves, it secretes a substance that allows harmful sooty fungi to develop.
To prevent the appearance of whiteflies, you should remove them in time. weed, water correctly, install special glue traps for insects. Only careful care and care of the gardener will bring a good harvest.
Timely and correct prevention of diseases and pests will increase its quality and duration of fruiting.
