Cucumbers are one of the earliest vegetables that appear in spring and most often grow in open ground. However, fruits grown in greenhouse conditions can be harvested almost year-round. This requires a greenhouse that will be warm without drafts, properly selected seeds, as well as compliance with agrotechnical measures.
All varieties of cucumbers can be divided into several classes:
By the time of collection:
- winter-spring collection;
- spring-summer ripening;
- summer-autumn varieties.
The speed of ripening cucumbers are:
- late maturity.
According to the method of pollination:
- for canning;
- for salads;
- for universal use.
Not all varieties are suitable for the greenhouse cultivation of cucumbers. The most suitable are self-pollinating and parthenocarpic species.
It should be noted that the 1st grade (self-pollinated) cucumbers have seeds inside the fruit, and 2 species do not possess them at all. In addition, these varieties have good yields and are resistant to diseases that are typical of cucumbers grown in the soil.
Lettuce cucumber varieties are grown smooth, with a smooth peel without thorns or with small thorns, which are always white. Their skin is rather thick and dense, which allows them to be transported over long distances without damaging the fruit.
Cucumbers, which are intended for canning, have a thin skin. This feature allows the marinade to penetrate evenly when salting. Such cucumbers are grown in large sizes.
If the variety is universal, then it can be eaten raw in salads, and also it is suitable for preservation. Varieties grown for salads are not recommended to be canned. This may adversely affect the taste preservation, as well as significantly reduce its shelf life. The purpose of the fruit is indicated by the producer on the seed packet.Tip! In order to be able to harvest almost constantly, it is rational to plant varieties of different harvesting periods in greenhouses.
Another option to achieve a similar result is planting cucumbers at a certain frequency, when previous plantings produce the first flower.
The advantages of greenhouse cucumber varieties
The presence of the greenhouse, which is equipped for the cultivation of cucumbers, provides several advantages:
- large yields;
- constancy of ripening;
- disease resistance;
- a large selection of varieties that can be used subsequently both in fresh form and in pickled.
There are some types of cucumbers that are able to give up to 30 kg per 1 square meter. meters.Attention! Varieties of Dutch breeding have increased resistance to disease. Therefore, choosing them, you can be sure of the final harvest.
In addition, the fruits obtained do not possess bitterness, and at planting they have almost 100% germination. Most of them are self-pollinating varieties.
Features of the Dutch varieties
In these types of cucumbers there are some features that must be considered when they are cultivated. These include:
- Seeding is done in the last days of March in pots;
- in the subsequent landing, the interrow distance is 2-4 cm;
- while the seeds are in pots, it is necessary to prepare a mixture that includes peat, rotted manure, soil and coarse sand. The mixture itself can be folded into peat pots for seedlings;
- after the cucumber seeds sprout, they are carefully planted in the prepared mixture in pots;
- then they wait for 3-4 leaflets to sprout, and land on the greenhouse for a permanent place. In addition, it is necessary to take into account that cucumbers, germinated from Dutch seeds, must be planted according to an exact scheme, the observance of which will ensure a proper high yield:
- along the length of the entire greenhouse, they are digging trenches, the depth of which is 40 cm. Pots with grown plants will be planted in them.
- the distance between the trenches should be at least 80 cm. This will allow them to grow in the future without interfering with each other.
- on the bottom of the prepared pits, put manure, a layer of at least 5 cm. Then you can proceed directly to planting.
- the plants themselves must be planted square
When the cucumbers start and grow, it is necessary to remove the first antennae and pin the tops. After the plants continue to grow and release the next series of whiskers, you can feed the cucumbers.
Some varieties of Dutch cucumbers
The secret of the frequency of planting Dutch cucumber seeds lies in their reliability, which provides not only high yields, but also greatly simplifies the process of caring for plants.
One of the representatives of the Dutch selection. Marking says that this type of cucumber is self-pollinating. The length of the fruit can reach 14 cm. Cucumbers of this variety are suitable for salads and other dishes, where they are used raw.

Its main characteristic is unpretentiousness at leaving. Belong to early grades.
Hybrid view of Dutch breeders. Cucumbers of this type have good keeping characteristics, therefore, transportation. It is referred to as mid-late varieties and, due to climatic conditions, is most suitable for planting in temperate latitudes.

It refers to the average yield, but its taste is excellent due to the presence of large amounts of sugar and ascorbic acids. The length of the fetus reaches 13 cm.
Early ripe cucumbers. Characterized by a dark green color of the skin with dense flesh. A distinctive feature is the fact that Zelentsy do not turn yellow and always retain their color. The size of the fruit, rather thin peel allow you to use them for conservation.
This type of cucumber is not tall, grows a bush, but with a large number of fruits. This growth greatly facilitates the care of the plant and harvest.
Cucumbers of small size, which belong to the gherkins. This is an early ripe variety that can grow at a reduced level of illumination of the greenhouse.

This plant is characterized by the fact that most of the harvest is concentrated on the central stem, so it does not need to be formed. Cucumbers have a delicate taste and do not taste bitter.
