Each vegetable crop has its own characteristics, which determine the timing and other details of sowing.
And if we talk about cucumbers, this heat-loving crop is planted as seedlings or seeds are sown in the ground. What you need to know about sowing in the ground, given the heat-loving nature and sensitivity of this crop.
First, you need to decide on the timing. It is better to focus on the air temperature (18-20 degrees Celsius during the day and not lower than +15 at night) and the soil temperature (15-16 degrees).
Lower temperatures will affect germination, and if it gets cold and the thermometer drops below +12, the seeds will rot or die.
You should also check your plans with the lunar calendar and avoid sitting on a new or last phase of the moon.
Therefore, in May we can immediately exclude the 19th (the new moon falls on it) and the 5th (the full moon).
You can plan sowing on May 2-4 and 6, from 13 to 15, 17, 22-24 and 30, 31.
At the same time, summer residents recommend giving preference to hybrids that are bred taking into account the climatic features of the region.
