cucumber urban garden Sowing the cucumber

Sow the cucumber seeds no more than 2 cm deep and cover them lightly. Cucumber seeds require a constant temperature of between 25 and 27ºC. Leave about 40 cm² for each cucumber plant.


The cucumber needs that the cultivated land with a pH between 5.5 and 6.5, that it has a good contribution of organic matter (you can use worm castings), that it allows a good drainage of the water, that the soil is loose and that it does not become caked.

The pot or grow table in which you plant your cucumbers should ideally be 40 cm deep.


Locate the cucumber plants in an area with good sun exposure. The more light they receive, the greater the fruit production.


These plants grow optimally in temperate climates, which do not exceed 30ºC and do not drop below 8ºC. Being above or below this temperature range can affect flowering and fruit formation.


The cucumber needs regular waterings to keep the soil with a constant degree of humidity. It is preferable to opt for drip irrigation, it can be very easy to install in urban gardens and thus we will save water and adjust well the quantities that the plants need, avoiding problems due to deficiencies or excesses.

Pruning the cucumber

Throughout the life cycle of this vegetable we will remove the leaves that we see that are in poor condition, that are yellowish, brown, etc. In addition, if we want to give more vigor to the flowering and fruiting process, we can remove some secondary stems and leave the main one and two or three more, maintaining a symmetry in the plant.

Cucumber Tutor

Being a creeping and climbing plant, it is necessary to guard the cucumber as it grows for several reasons: to promote a regular development of the plant, better use of light, increases flowering and fruit growth, and prevent fungal diseases and pests. See how to tutor plants .

Crop associations

It is important to consider what other plants you can grow next to the cucumber so that there is a synergy between the plants, especially if you use large planters or grow tables. The cucumber can be combined well with spinach, chard, beet, lettuce or sunflower.

Cucumber pests and diseases

Aphids, thrips, whiteflies, caterpillars or spider mites may appear, while in diseases, the most common is powdery mildew. All of them can be prevented and treated in an ecological way, see here .

Cucumber harvest

Depending on the growing conditions and the variety of cucumber that we are growing, from when we start to sow the cucumber until we harvest it, 100 days may have elapsed.

Possible problems during cucumber cultivation

  • If you see that the fruits have cracks, it may be because there is a significant temperature difference between day and night and the cucumbers suffer.
  • If the cucumbers are yellow, the causes can be several: lack of light, lack of irrigation or excess nitrogen or potassium.
  • If the cucumbers curl or narrow at the ends it may be due to lack of water or too high temperatures.
