The soil requirements are not strict, and it is advisable to take pH7~8. There is a greater demand for nitrogen fertilizers, followed by phosphate fertilizers and potassium fertilizers. Seeds can be sown in both spring and autumn. Autumn sowing is the mainstay, with a growth period of about 60 days. In northern China, there are also winter sowing and spring harvesting, commonly known as spinach. Strip sowing or sowing.

Cold-resistant and heat-resistant vegetables, the temperature exceeds 25 that is, poor growth, poor quality, if the use of summer spinach efficient cultivation technology, June to July can also be planted, August to September can be marketed supply, the economic benefits are very high.
