2 hydroponic bamboo, remember not to direct sunlight, especially the root ventilation astigmatism is the best.
Water will settle for several days. When changing water, the temperature difference with raw water should not be too large. You can take root by hand. Change the water two or three days before rooting. After taking root, the water is not muddy. There is no need to wash the leaves with precipitation. Pour out from the bottle and keep 2/3-3/4 water.
The roots of Fu Guizhu are very dense, so don't keep them in small bottles.
After rooting, put a clean nail in the bottle and drop a few drops of hydroponic nutrient solution every few days.
