1、 Soil

Watercress green is suitable for growing in soft soil with strong drainage capacity. It will grow poorly if the soil is too viscous. Pot culture can mix rotten leaf soil, river sand and some base fertilizer, or peat soil and perlite

2、 Sunshine

It likes to be illuminated by natural astigmatism and can be raised in a place with astigmatism in the house. It doesn't matter if the sun is not very big in spring and autumn. But in summer, it will be shaded, which can be placed on the balcony to the north. Too strong or too weak sunlight is not conducive to its growth, so don't keep it in too dark places

3、 Moisture

During the vigorous growth of plants, sufficient water is required, and the amount of watering can be slightly more. The temperature will rise in midsummer. You can water more appropriately, but pay attention to ventilation to avoid stem and leaf rot caused by high temperature and humid climate. It can grow in a dry environment for a short time

4、 Fertilizer

In spring and autumn, a small amount of fertilizer and water can be applied many times. The concentration of fertilizer should be low, and raw fertilizer should not be applied. Fertilizer can be applied once every 10 days, and a small amount of nitrogen fertilizer should be applied to flower and leaf varieties. Generally, fertilization is not needed in summer and winter, which is prone to rotten roots

5、 Precautions

When the seedlings grow to 10cm high, they should pick the heart, which is conducive to the growth of new branches. We should also pay attention to the prevention of diseases and pests. Plants are easy to cause diseases and pests in high temperature and humid environment, so we should pay more attention to ventilation
