Orchids have a reputation for being difficult. One problem people run in to is not knowing how much water to give orchids. People tend to over water them, when they don’t really need that much water to survive. A good suggestion for knowing when to water is to put your finger into the soil about an inch, and if it’s dry, water the plant. Orchids should also be watered in the morning, and thrive in humid environments.
Key Takeaways:
- Despite the fact that they’re tropical and like humidity, orchid water requirements are actually pretty low. In general, orchids like their growing medium to dry out between waterings.
- To test this, put a finger in the growing medium. If it’s dry about an inch down, it’s time for watering.
- Always water your orchids in the morning so the moisture has time to evaporate.
“Perhaps the biggest mistake people make when growing orchids is overwatering them.”
