Cucumbers are one of the most popular and loved vegetables in the world, thanks to their delicate taste and their beneficial properties for health.In our article today you will learn how to grow cucumbers in a simple and effective way , starting from planting techniques to harvesting and storing the crop.
Cucumber Plant Classification
The cucumber plant is classified as Cucumis sativus and belongs to the Cucurbitaceae family, which also includes other plants such as squash, melon, and ornamental gourd. The complete classification of the cucumber plant is as follows:
Kingdom : Plantae (plants)
Division : Magnoliophyta (flowering plants)
Class : Magnoliopsida (dicotyledons)
Order : Cucurbitales
Family : Cucurbitaceae
Genre : Cucumis
Species : Cucumis sativus
The cucumber plant is an annual climbing plant that produces edible fruits in the shape of a cylinder or sphere. Cucumbers are native to Asia, but are now cultivated throughout the world as a vegetable.
Land selection and soil preparation
To grow cucumbers, it is important to choose a well-drained, fertile soil rich in organic matter . If you have a vegetable garden, you can prepare the soil using organic fertilizer or compost, or you can buy specific soil for vegetables. In any case, it is important that the soil is soft and free of stones and roots.
Sowing cucumber
Sowing cucumber seeds can be done directly in the ground or in a pot, depending on your needs. In the first case, it is important to wait until the soil temperature is above 18°C, to avoid the risk of root rot.
Alternatively, you can sow the seedlings in pots and then transplant them into the ground once they have grown enough. The ideal distance between cucumber plants is about 50-60 cm.
How to Water Cucumber Plants
Cucumbers are plants that require a lot of water , especially during the growth phase. It is therefore important to water regularly , but avoid wetting the leaves, to prevent the appearance of diseases. In case of very dry soil, it is possible to water more intensely, preferably in the evening or early in the morning.
Cucumber mulching
Cucumber mulching is a useful agronomic practice to improve the health of plants and the quality of fruits , but it is important to choose the type of mulch based on the soil conditions and climate of your area.
Remember that mulching consists of covering the soil around plants with an organic or inorganic material to improve the quality of the soil, limit the growth of weeds and maintain soil moisture.
As for cucumbers , an ideal mulch can be obtained using straw, dry grass, dead leaves, chopped bark, gravel or a sheet of specific synthetic material .
The goal of cucumber mulching is to keep the soil cool and moist during the summer season , which prevents water loss through evaporation and reduces water stress on the plants. Mulching also helps prevent weeds from growing around the cucumber plants, which could compete for water and nutrients with the cucumber plant.
To obtain an ideal mulch around cucumber plants, we recommend you follow these simple precautions.
- Remove all weeds and plant debris from the soil around the cucumber plants.
- Spread a layer of mulch about 10-15 cm around the cucumber plants, avoiding covering the collar of the plant.
- If you use an organic mulch such as straw or dry leaves, replace it every 2-3 weeks, so as to prevent the formation of mold and decay of the material.
- Make sure the soil around your cucumber plants is adequately watered.
Fertilizing Cucumber Plants
Cucumbers are plants that require a good amount of nutrients to grow properly. During the growth phase, you can apply natural fertilizers to encourage the development of the plants. For example, organic fertilizer based on horse or cow manure can be used in moderate quantities to nourish the soil and make the plant stronger and more resistant to diseases.
Cucumber trimming
Cucumber trimming is a pruning technique that involves removing the tip of the plant’s main shoot. Trimming is done to encourage branching of the plant and increase fruit production .
The pruning technique must be performed when the plant has reached a certain height, generally between 30 and 40 centimeters, and has at least 5 or 6 leaves. Pruning is performed by delicately cutting the upper part of the main shoot just above the last leaf .
After topping, the plant begins to produce new lateral shoots, which in turn develop flowers and fruits. This branching process allows the plant to produce more fruits in a more concentrated area of space, thus optimizing the yield of the crop.
Pruning must be done with care to avoid damaging the plant. Furthermore, pruning is not always necessary and whether or not to do so depends on the cucumber varieties grown and the growing conditions. For these reasons, it may be worth seeking advice from an experienced grower before doing so.
Pests that can attack cucumbers and diseases
The healthy growth of cucumbers is especially endangered by aphids . To keep them away you can use natural remedies such as chilli pepper , rhubarb and garlic . To eliminate them we recommend trying to use nettle macerate and neem oil , avoiding chemical insecticides.
Pruning can be an additional way to eliminate aphids that are infesting part of your garden.
Other enemies of the cucumber on which we have written dedicated articles and which we refer you to for more information are whiteflies and red spider mites .
Among the diseases that can affect cucumbers, we would like to point out grey mould or botrytis and pythium .
Picking cucumbers
Cucumbers are ready to be harvested when they have reached a size of about 20-25 cm and their skin is still smooth and deep green. It is important not to wait too long to harvest them, otherwise their flesh will become soft and the flavor will be less intense. Cucumbers can be harvested by hand, simply by detaching them from the plant with a sharp knife.
Storing Cucumbers
Cucumbers can be stored in the refrigerator for a few days, wrapped in a plastic bag or aluminum foil . Alternatively, you can preserve them in salt.
Nutritional properties of cucumbers
Cucumbers are a low-calorie vegetable , composed mostly of water. Every 100 grams of fresh cucumber contains about 15 calories and only 0.65 grams of protein, 0.11 grams of fat and 2.16 grams of carbohydrates .
Cucumbers are also a good source of vitamin C , an antioxidant that helps protect cells from oxidative stress. Cucumbers also contain vitamin K, vitamin A, potassium, and folate .
Cucumbers are also known for their fiber content, which can help maintain regularity and make you feel full, thus preventing obesity. Most of the fiber is found in the peel of a cucumber, so it is important to eat it with the peel to maximize the benefits of the fiber.
