1. Ideal soil

The growth of Douban green requires loose, fertile and well drained sandy loam. If the soil used is too sticky, it will affect its normal growth

2. Suitable temperature

To make it flourish, it should be given a growth environment of 10-30 ℃. Too high or too low temperature will directly lead to its poor growth and irradiate it with bright scattered light

3. Rational fertilization

During the growth of watercress green, it is best to give it thin fertilizer every half month in spring and autumn. Change the soil for it every two or three years. In addition, during its growth, it can sprout lateral branches by picking the heart, so that it can grow more luxuriantly
