1、 Water quality

Crested eye blue is usually cultured in water, so water control is very important. It should be cultured in shallow water where the water flow speed is low. The flower stems can grow as long as they are exposed to water, but the ovary can develop only in water. Therefore, there should be not only oxygen but also nutrients in the water

2、 Temperature

It is suitable for growing in an environment with a water temperature of 18 degrees to 23 degrees. The maximum temperature can not be higher than 38 degrees and the minimum temperature can not be lower than 10 degrees. Otherwise, it will stop growing. Heating rods can be used to increase the temperature in winter

3、 Illumination

It likes light very much. It is best to give full light during breeding. If it is in a cool place without light, it will lead to poor development, reduce the number of flowers, and may lead to plant wilting. However, when the light is too strong, it is still necessary to block the light to avoid sunburn to the branches and leaves

4、 Fertilization

Fertilizer should be applied frequently during the maintenance and management period, about once every half a month to 20 days. The fertilizer mainly uses rotten manure or diluted ammonium sulfate. Pay attention to the low concentration, because it is easy to reproduce itself

5、 Precautions

At the initial stage of growth, it is easy to be affected by weeds or moss. They will grab nutrients and slow down the growth rate. Pay attention to remove them in time. In addition, it is easy to be eroded by aphids, so drugs should be sprayed for prevention and control
