1. Soil

Douban Green likes loose and fertile sandy loam with good drainage. In the maintenance process, rotten leaf soil or peat, garden soil, river sand or perlite can be used for cultivation in the proportion of 4:3:2

2. Illumination

Watercress green can withstand half shade, but likes bright light. In the process of curing, it should be placed in a bright place. Direct sunlight should be avoided at noon in summer and can be accepted in winter

3. Watering

To keep the basin soil slightly moist, the water should not be too much. If the water is too much, it is easy to cause root rot. Watercress Green's drought tolerance is still relatively high. We must pay attention not to water too much

4. Fertilizer

Watercress green does not require very high fertilizer. Under normal circumstances, it can grow well. For indoor maintenance, thin liquid fertilizer is applied to it every half a month in spring and autumn, or 5-10 slow-release fertilizers can be put into a basin

Changing the soil once every 2-3 years can basically meet its growth

5. Precautions

If the water is sufficient and the environment is dark, it will grow in vain. After overgrowth, the plant shape can be fuller through construction, so that it can achieve an ideal ornamental effect
