Overwatering is one of the most common ways to harm an orchid. To ensure your orchid receives the perfect amount of water, we at Just Add Ice® advise you water your 5-inch orchid on the same day each week by placing three ice cubes on top of the media. (Use one ice cube once per week for mini orchids.)
Studies show watering orchids using ice cubes does not harm the plant. One recent study observed the effects of different watering methods on 10 varieties of Phalaenopsis orchids over the course of several months. The study concluded that, not only were there no detrimental effects on leaf or root health when watering with ice, some of the ice-treated plants actually had a longer display life and flower longevity.
