Generally, it is in the middle of August. Guayeju like cool climate, not hot and high temperature, moderate growth temperature of 15 ℃ - 20 ℃. The seeding box should be placed under the shade, or under the shade of trees; if border seeding is adopted, the shade must be set up above the border soil to reduce the radiation heat of the sun.
The potting soil was composed of 1 part of garden soil, 2 parts of rotten leaf soil, 2 parts of rice husk ash, a small amount of rotten basic fertilizer and superphosphate.
