1、 Direct purchase

In one case, we bought watercress green directly from the market, so we only need to carry out appropriate maintenance according to the original plants

2、 Prune and take root by yourself

The other is that we trim the green branches of watercress in our family and put them in a hydroponic environment to take root. In this case, we can take measures such as shading the container of hydroponic culture when rooting, and adding appropriate rooting agent. Create a good growth environment for it, mainly scattered light, control the temperature above 10 ℃ and below 30 ℃ and moderate ventilation. Such an environment can promote its rapid rooting. After rooting, we can see that there are obvious roots in the hydroponic environment, and then we can appropriately add fertilizer to the water to promote its normal growth
