What is the effect of soaking orchids in rice vinegar solution?

The main purpose of soaking orchid plants in rice vinegar solution is to carry out a comprehensive sterilization of the orchid plants, because rice vinegar has a good bactericidal effect, and its action is different from chemical sterilization: it can penetrate every corner of the orchid plant, so the sterilization is relatively thorough. In addition, diluted rice vinegar solution can dissolve fertilizer crystals on the surface of the orchid plant and soften the root stiffening caused by fertilizer damage. Soaking the orchid plant in a 1/2500 rice vinegar solution can achieve the above effects. Of course, increasing the concentration to 1/1000 is also acceptable. As for the ratio of rice vinegar solution for watering, it depends on the pH of the growing medium you use; watering with rice vinegar solution is only to bring the pH of the growing medium to the level required for growingorchids. It has no direct relationship with strong seedlings.
