Autumn is the time to harvest, for some crops last in the year. But you want to eat fresh vegetables not only in summer. If everything is done correctly, then to the very cold weather, crunchy green cucumbers will delight the whole family, recalling the past summer.
By growing cucumbers in the greenhouse in the autumn, it is appropriate to start preparing at the end of summer. The temperature of the air with the arrival of autumn cool often often does not allow the seedlings to develop in the open ground. In September, everything should be ready for planting seeds, from which young cucumber shoots should soon grow. The first necessary action is the preparation of the greenhouse.
If some vegetables were growing in the greenhouse during the summer period, then the ground should be cleaned from residues of leaves, shoots and roots.
The frame of the greenhouse can be wooden or metal. In any case, the material of the frame before planting seedlings need to be processed: wood - with a solution of bleach or water-based paint, metal - copper sulphate. This is done in order to protect future shoots from pests, rust and mold, which can settle on the frame of the greenhouse.
The main materials used in greenhouses are film, glass or polycarbonate. Film - the simplest, but not the most durable type of coating. It is used more often for temporary summer greenhouse options. If you plan to plant cucumbers in such a greenhouse, then you need to carefully check the integrity of the coating and provide protection for young shoots from cold condensate, which is always formed on the film in the morning. Because of it, plants can freeze and die.
Polycarbonate greenhouse is the most durable and reliable option, but it costs a lot of money.
Therefore, installing it because of 3-5 kg of cucumbers is not worth it. But if growing cucumbers in a greenhouse is a profitable business, then you should not skimp on a good polycarbonate greenhouse with heating, lighting and air ventilation.
Preparation of seedlings and planting cucumbers in the ground
In September, the temperature of the soil in central Russia still allows planting seeds in a greenhouse directly into the ground.Important! Cucumbers are heat-loving plants, so that the seeds germinate and do not die, the temperature of the soil should not be below 12 degrees.
If there are concerns that it will be cooler at night, the seeds can be planted in special pots, which are installed in the greenhouse before the shoots germinate.
When planting cucumbers in the open ground of a greenhouse, one has to pre-treat the soil in order to get rid of harmful bacteria, decay and weeds that could harm the future crop, and also create places for beds. Preliminary soil preparation before planting involves several steps:
- The soil in the greenhouse is removed by 5-10 cm to remove from the soil the unwanted elements left over from the previous plantings.
- The land should be treated with diluted lime and fertilizers, organic and mineral. If we are talking about compost and not rotted manure, then for their laying small recesses are made, in which you need to lay out the selected type of fertilizer at the rate of 20 kg per 1 m2.
- The beds can be located in the greenhouse as it is convenient to its owner. But if you plan to combine the cultivation of cucumbers with other types of vegetables, then the side for planting cucumber seedlings should be sunny. The height of the beds can be from 20 to 30 cm.
- Before planting cucumbers in the beds, holes are made at a distance of at least 30 cm. This is necessary so that the bushes do not interfere with each other as they grow. Too close planting of cucumbers reduces their yield and fruit quality. Before planting seedlings, it is necessary to water the hole. Then gently stick the root of the shoot and sprinkle it with earth. Watering seedlings immediately after planting is not required.
- Planting of ready seedlings is done when the height of the stem reaches 15-25 cm. It is worth taking care in advance of preparing trellises, to which it will be necessary to tie growing shoots.
A special feature of planting cucumbers in the greenhouse in the fall is that during this period of time, nitrogen fertilizers are not needed. It is enough to treat the soil from pests and enrich it with manure. Particularly suitable for these purposes chicken droppings, previously soaked in water. Fertilizers with nitrogen content are used only in spring.
Caring for cucumbers in the greenhouse
Cucumbers are plants that love moisture. The moisture level in the greenhouse must be at least 80%. But this does not negate the regular watering of vegetables. It is enough to hold it every other day. If autumn is sunny and hot, you can water cucumbers daily. Watering cucumbers should be done with water at room temperature, strictly under the bush, making sure that the spray does not fall on the leaves.
For this it is better to use a watering can with a special nozzle. You need to make sure that the water pressure when watering is not too strong.
After all, it can damage the young root system of vegetables. Do not use too much water. Excess moisture will cause rot and death of plants. In the middle of autumn at a lower temperature it is possible to water cucumbers less frequently, about 1 time in 10 days. Water consumption per 1 m2 should be approximately 8-9 liters.
As the air temperature decreases, the soil gradually cools. If the greenhouse is not additionally heated, then young cucumbers in the fall cannot get all the necessary nutrients from the soil and need additional feeding. The best option would be water-soluble fertilizers that can be sprayed on the bushes. But their use should be carried out in strict accordance with the instructions on the packaging.
How to care for shoots
Growing shoots of cucumbers need to pinch from the moment they reach a length of 50 cm. This is done as follows:
- Lower side shoots are removed with a secateur.
- Side shoots taken to pinch over the first leaf.
- The upper part of the main shoot and the top shoots are fixed above the second leaf.
All excess antennae, dead ovaries, dry leaves and parts of the side stems should be removed in a timely manner so that they do not interfere with the development of the main fruiting escape. In order for the crop to be large, and the fruits of cucumbers grow to medium sizes, it is necessary not only to maintain the level of humidity, to fertilize and water the plantings. It is important to ensure that fresh air enters the greenhouse. Airing is recommended 1-2 times a week. However, strong autumn drafts can harm young plants, so it should be done very carefully, if necessary, covering the stems with a film.Tip! For growing cucumbers in the autumn it is better to choose frost-resistant, unpretentious varieties.
These include hybrid varieties of vegetables. They are resistant to small temperature extremes, pests, and at the same time produce high yields even in adverse conditions. Subject to all rules for the care of cucumbers harvest can be removed 1-2 times a week.
