How to care for cucumbers in a greenhouse from planting to harvest

What temperature should be maintained in a greenhouse?

The greenhouse was so named because it has additional heating, and favorable air temperature is the main criterion for growing new plants during cooler weather. Only if a gardener can maintain a certain air temperature in the room will the plants thrive and produce a rich harvest. First, it's worth considering that seedlings will only grow and develop normally at an air temperature of around 20 degrees Celsius during the day, and in the evening, it's quite possible to lower the air temperature by a few degrees. This is the temperature that must be maintained for growing. cucumbers in a polycarbonate greenhouse.

When the fruiting season arrives, it's worth learning how to care for cucumbers in a greenhouse from planting to harvest (video). After all, when the first fruits appear on the plants, the air temperature should be higher than during the growth and development of small bushes. The soil temperature can be as high as 24 degrees Celsius, and the air warms up to 28 degrees Celsius on a sunny day. In cloudy weather, the thermometer can drop by 5 degrees, and at night, the air should warm up to at least 20 degrees Celsius. It's crucial to monitor the temperature; sudden cold snaps or overheating are not beneficial for the plants, especially severe cooling of the soil and indoor air.

How to maintain room humidity?

Greenhouses are a great place to grow various vegetables, especially because cucumbers thrive in relatively humid conditions. Therefore, during flowering and growth, the plants should be kept in a room with humidity levels of up to 80 percent. When fruiting time arrives, the humidity level should be raised to 90 percent. To achieve this humidity level, it's essential to water and mist the plants correctly and at the right time.

The correct process of watering plants

Caring for cucumbers in a greenhouse from planting to harvest (video) also requires constant soil moisture. Plants dislike excessive moisture, and too little water will cause the cucumbers to develop a bitter taste. Water should be used only warm; the temperature can be raised to 25 degrees Celsius, but it should not be boiled. Before the plants begin to bear fruit, water the soil no more than once every three days, as the sun does not evaporate the moisture from the soil. Once the first fruit buds appear, water daily, using seven liters of water per square meter of soil.

To care for cucumbers in a greenhouse from planting to harvest (video), various irrigation methods are used. The only exception is the subsoil method, as it is not recommended for use in a greenhouse. It's best to use various watering cans with a sprayer or a hose with a nozzle; this will allow you to water not only the soil but also the foliage. To increase humidity in the greenhouse, water all paths and walls. After watering, it's recommended to open the front door and windows for ventilation. This will help prevent stagnant moisture, which will cause the liquid to evaporate and increase humidity. It's important to know: How to feed cucumbers in a greenhouse using folk remedies.

There's a little trick to watering your plants. If done correctly, it can significantly increase the production of female flowers, which means more fruit sets. To increase fruiting, it's recommended to slightly reduce the amount of soil moisture, and then, once the plants reach the end of flowering, simply water them again as before.

Is there a need for complementary feeding?

Proper care of cucumbers in a greenhouse from planting to harvest (video) should also include additional fertilization of the soil with nutrients. While open soil contains a significant amount of nutrients, the shelves and boxes where the seedlings are growing may lack sufficient nutrients, which is why plants need to be fertilized. Gardeners recommend fertilizing cucumbers in a greenhouse every ten days by watering them with mineral fertilizer applied to the roots. Gardeners recommend alternating these applications: watering first, then spraying the plants with a weaker solution ten days later. While root feeding works best in sunny weather, foliar feeding is only effective in improving growth and fruiting on cloudy days.

In some cases, plants also require special micronutrient feeding. This is important when it's fairly cloudy outside and indoor lighting is too low to provide sufficient light for small plants. This feeding is applied at the roots and should be done no more than twice a month.

Cucumbers also need bush formationTo achieve this, pinching is essential when the bush reaches fifteen centimeters. If the plant has already reached twenty centimeters, this procedure will not increase the yield. Each bush is tied with a string or wire, making it easier for the gardener to harvest the crop, and preventing the plant's vines from getting in the way when watering and fertilizing.
