Water lily is usually planted in the soil, and then poured into a certain amount of water for maintenance. Usually, it does not need to be watered. If the water is changed, there is no time limit.
Generally planted in water, do not need too much water to ensure water supply, just need to change the water in the water tank regularly. The water change is also based on the specific situation. The best way is to use a plastic pipe to suck out the impurities at the bottom, and then change the water by about one third. If it is to add tap water, it needs to be dried in advance to ensure that the water temperature is close to the temperature of flowers, and the temperature cannot deviate too much.
The amount of water added each time should not be too much, just do not exceed the stem of the water lily, but pay attention not to cover the leaves, otherwise the leaves will show signs of decay.
The frequency of water change doesn't need to be too high. In the high temperature period, water change is about 20 days. If fish are raised, the frequency of water change can be increased. In normal growth, it is not necessary to change water too frequently, and the frequency can be kept moderate, and it can be added properly after the water level drops. Note that if you change water too often, it may affect growth.
