Spinach as a day-plant is strongly influenced by the the long day, that is, during the days, they get longer. The plant’s tendency increases.to stem and flowerAlthough other climatic factors such as heat can accelerate the flowering of spinach, it is not the major factor, and the duration of the light only will play a major role, so if the duration of the light is less than 12 hours, the spinach will not bloom. Spinach is an allogamous plant in terms of inoculation and its pollen grains are transported by wind.
Climatic and soil conditions for planting spinach
Spinach is not very sensitive to the weather and it is a product of the cold season. Adequate air and soil moisture have a positive effect on the growth and quality of spinach. In very cold regions, winter spinach is damaged
Spinach is one of the plants that has very deep roots and, as mentioned, penetrates into deep loamy silt soils up to 40.1 meters. Therefore, shallow or impermeable soils are not suitable for planting spinach. It grows in sandy and light soils but will not produce enough.

Remember that spinach needs moisture but should not get too wet. When the temperature reaches above 80 degrees Fahrenheit, you should cover the plants to maintain their normal humidity.
Since spinach is a heavy food, you should add 5 to 10 cm of fertilizing minerals per 9 square meters. Feed the plants with nitrogen-rich compounds every two weeks to increase their production. Plants should be at least 10 to 15 cm deep in the ground to be less at risk, and be sure to moisten the soil after fertilizing.
You can weed at least 7 and a half to 13 cm of these plants and let the plant energy increase.

Plant mold only attacks spinach in humid areas.
You can prevent this by keeping the plants away from each other so that enough air can reach them.
Mold attacks the plant when the air is too humid.
