1、 Soil selection

Douban Green likes loose and fertile sandy loam rich in humus and good drainage. In the process of curing, we try to avoid using sticky soil, otherwise it will affect plant growth or cause root rot

2、 Mixed preparation

In the process of daily maintenance, we can use rotten leaf soil or peat, clay, river sand or perlite to mix and prepare in the proportion of 4:3:2. Disinfect after mixing evenly to keep the soil water content of about 40%. In this way, it can be maintained and cultivated normally. When configuring the soil, in order to maintain good fertility of the soil, rotten organic fertilizer can be added to the soil as the base fertilizer. Only by using suitable soil can it grow normally
