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

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.
Instead of weeding the plants and causing damage to the roots, it is better to do this with scissors, which will increase the growth of the plant.
