In addition to keeping the cultivation substrate moist during the growing period, half of the water should also be put into the leaf tube, but the water should be changed once after two or three days to prevent the water from smelling in the tube and affecting plant growth.

2. Long-term lack of water leads to yellowing of water tower flower leaves (dry yellow):

The leaf edge and leaf tip of the water tower flower are very easy to scorch, so it is necessary for us to keep the basin soil moist.

Solution:

Solution:

Increasing air humidity can prevent the scorch caused by excessive evapotranspiration. In general, the use of high-pressure spray (small steel gun) can increase air humidity and achieve the effect of cooling at the same time. The principle is that small water droplets are used to take away excess heat from the greenhouse in the process of evaporation. However, the cooling efficiency is slightly lower in the already humid environment of southern China.
