Orchid Watering
Many people make the mistake of over watering their orchids. They don’t need to be watered continuously and doing so can severely harm their root system and lead to problems such as disease and root rot. Use the following as a guide for watering your orchids:
Water your orchid thoroughly once and then allow the media to try out before watering again. The top layer of the pot should be dry to the touch before watering the plant anymore. The trick is to water them enough, but not too much. This may seem like stating the obvious and it lots of ways it is, but its important to remember.
Another important factor is water quality. Rain water is by far the best option and is my recommendation. I try to avoid tap water because on a few occasions doing so has severely hurt my orchid.
Good luck with your orchid watering
