Orchid Watering Methods: Handling Five Key Relationships Well
1. Watering and orchid species. Because each orchid species has different growth habits, its water requirements also vary. Cymbidium ensifolium likes moisture, but waterlogging in the growing medium must be avoided. Cymbidium sinense prefers dry over wet; too much moisture easily causes root rot and plant collapse. Cymbidium kanran has a well-developed root system and strong drought tolerance, so the potting soil should be kept on the dry side. Suxin orchids and leaf-variegated orchids require seven parts dry and three parts wet; too much moisture easily causes degeneration. 2. Watering and orchid pots. Clay pots have a rough texture and strong air permeability, and moisture evaporates easily, so water frequently, water generously, and water thoroughly. Plastic pots have low density and poor air permeability, and moisture is consumed slowly; in summer,
