1、 Reduce water

When raising lilies in water, if too much water is added, the growth of plants will be limited, the respiratory function will be limited, and there will be no flowering. Water for hydroponic culture can be appropriately reduced, which can promote the flowering of plants as soon as possible

2、 Regular water change

The main nutrition of water nutrition comes from the water quality inside. If you don't change the water all the time, the nutrition inside will be exhausted. In this way, you can't absorb nutrition from inside and fresh water, but you can't change the water every day. The spring and autumn seasons are changed every 3-4 days. In summer, when the temperature is relatively hot, it needs to be changed every two days. In winter, it can meet the growth about once a week. The higher the temperature, the more frequent the water change

3、 Pay attention to pruning

It is soaked in water for a long time, so that the bottom will begin to rot and the function of transporting water will be weakened. The branches can be cut regularly, and the length of one centimeter can be cut from the bottom. Pay attention to cutting obliquely, so as to increase the cross-sectional area of water absorption

4、 Drip nutrition

It is far from enough to rely on the nutrition in the water alone. It is also necessary to add nutrient solution to it to supplement the nutrients needed for growth
