Since spinach is about 91% water, it grows in cool areas. It performs best in regions whose daytime temperature never exceeds 75 degrees Fahrenheit. So if you live in a hot climate, you should choose drought-tolerant plants.

The recommended temperature range is between 45- and 68 degrees Fahrenheit, but a mature plant can tolerate slightly higher or lower temperatures.

However, don’t grow spinach in regions that experience low temperatures below 20 degrees Fahrenheit.

Spinach requires more water to grow. Since the roots are shallow, frequent watering or irrigation can help make the plants happy.

It needs about 1-1.5 inches of water a week, but you don’t have to keep this routine. It is recommended to water spinach several times a week during the dry season.
