1、 Cause

Phalaenopsis is a perennial herb, which grows in the tropical rain forest with high temperature and humidity. It is an air root organism. Its roots are not afraid of water, so it can grow in water. There is a symbiotic orchid fungus in the root of orchid. During hydroponic culture, inorganic fertilizer should be prevented from killing orchid fungus

2、 Hydroponic method

1. Root cleaning: remove the rotten roots and old roots of the roots, and then soak them with insecticides and sterilizers, and then place the plants in a cool place to dry

2. Choose a container: choose a transparent glass or plastic container. The transparent container is convenient to observe the growth of the root and is more beautiful at the same time

3. Fixed plant: insert the dried plant into the container. If the plant cannot be fixed, look for a wire of appropriate thickness to wrap it into a ring, wrap the root and stem together, and then hang it on the mouth of the container

4. Water spray curing: after fixing the plant, pay attention not to let the water touch the root as much as possible, and spray an appropriate amount of water according to the humidity of the air. When planting, you can add some organic nutrient solution or a small amount of sugar water
