How to Grow Cucumbers organically

Growing cucumbers - cucumber seedlings ready for transplanting

Cucumber seedlings ready for transplanting

The cultivation of cucumbers prefers a warm temperate climate. To avoid stressing the plant, in the initial stages of growth, it is absolutely necessary to avoid cold temperatures and the risk of frost. It is therefore better to delay the transplant and not risk burning the small seedling with the cold. Therefore, for sowing in a seedbed, it is advisable to start in March in a protected environment. It takes about thirty days of development to go from seed to seedling. The transplant in the ground can take place from the month of April, preferably in the second half, when the risk of frost is averted.
The last date for transplanting is recommended not to go beyond the beginning of the month of July. Considering the period of growth before reaching fruit, 45-60 days, there is a risk of going too far with the cultivation period, excessively exposing the cucumber cultivar to rain and the first autumn cold.


The cucumber belongs to the family of cucurbits and, like the solanaceae, needs a lot of organic matter. If you intend to cultivate it, therefore, alternate annually with lighter crops, in order to preserve the structure of the soil. By paying this attention you can always have healthy and lush crops. For example, after cucumbers, you can grow, on the same plot, a sowing of turnip greens, a crop that resists winter frost and moreover does not tire the soil. Or you can opt for a legume, such as peas, which will enrich the soil with nitrogen. Or again, you can opt for a leafy vegetable, such as lettuce, spinach, or chard.

Soil Preparation

The soil for growing cucumbers must be well worked and rich in organic matter. Therefore, it is advisable to prepare the soil in the autumn period, incorporating mature manure or compost. The soil must be well drained and have a pH between 6 and 7.5. It is also advisable to add a good amount of potassium and phosphorus to the soil, which are essential for the development of the plant and the fruits.


Cucumbers can be sown directly in the ground or in a seedbed and then transplanted. If you choose the first method, you can sow from April to June, burying the seeds about 2 cm deep and leaving about 40 cm of space between one plant and another. If, on the other hand, you prefer to sow in a seedbed, you can start in March and then transplant the seedlings in April-May, when they have developed 3-4 true leaves.


Cucumbers need regular watering, especially in the summer months when the weather is hot and dry. However, it is important not to overdo it to avoid water stagnation and the onset of diseases. It is advisable to water in the morning or late afternoon, avoiding wetting the leaves.


Cucumbers benefit from regular fertilization. You can use a good organic fertilizer, rich in nitrogen, phosphorus, and potassium. It is advisable to fertilize at the time of planting and then repeat every 3-4 weeks during the growing season.

Pests and Diseases

Cucumbers can be attacked by various pests and diseases, such as aphids, powdery mildew, and downy mildew. To prevent these problems, it is advisable to rotate crops, avoid water stagnation, and use resistant varieties. If necessary, you can use organic pesticides or biological control methods.


Cucumbers can be harvested when they reach the desired size, usually when they are about 15-20 cm long. It is important to harvest regularly to encourage the plant to produce new fruits. The cucumbers should be cut from the plant using a sharp knife or scissors, taking care not to damage the plant.


Freshly harvested cucumbers can be kept in the refrigerator for about a week. If you want to preserve them for a longer period, you can pickle them. To do this, simply wash the cucumbers, cut them into slices or leave them whole, and put them in jars with vinegar, salt, and spices.

Use in the Kitchen

Cucumbers are very versatile in the kitchen. They can be eaten raw in salads, used to prepare cold soups, or pickled. They are also excellent in sandwiches and wraps, and can be used to garnish cocktails and drinks.

Benefits and Properties of Cucumbers

Cucumbers are not only tasty but also very healthy. They are rich in water and low in calories, making them perfect for those on a diet. They also contain various vitamins and minerals, including vitamin C, potassium, and magnesium. Furthermore, they have diuretic properties and help to purify the body.
In conclusion, growing cucumbers is not difficult and can give great satisfaction. With a little care and attention, you can enjoy fresh and tasty cucumbers all summer long.
