Rich and noble bamboo can be cultured with water, but do not add too much water when cultivating in water. Normally, the water level is above the root of the plant, that is, as long as the water can cover its root system. But also can't be too short of water, if the water is too insufficient, it will have a great impact on its growth
It is necessary to change water during the growing period, especially during its rooting period. Generally, water should be changed every 2-3 days when there is no long root. The purpose is to ensure the water is clean and has enough activity.
But for the plants that have taken root, it is not necessary to change water too frequently. Usually, it is only necessary to add some water to them properly. However, it should be replaced every few months, otherwise it will get dirty.
When changing water, do not just change water, but also clean the container of hydroponics. If not cleaned, even if the water is changed, there will be impurities, which will also affect the growth of the plant.
