How often should I water my orchids?

You've probably nailed the problem - orchids are way more forgiving when you let them dry out between waterings than when you keep them soggy. With bark media you're actually in a good spot because it drains fast, so you can be a bit more generous than someone using moss.

The general rule I follow (learned this the hard way after losing three phalaenopsis orchids in a row back in 2019) is to water when the bark is almost completely dry. Stick your finger about an inch into the media - if it feels dry, water thoroughly until it runs out the bottom, then let it drain completely. For most orchids in bark media during the growing season, that usually means once a week, maybe every 5-7 days depending on humidity and temperature in your space. North-facing windows are actually ideal because you're getting consistent light without the intense afternoon heat that can dry things out too fast. In summer 2026 I've been watering my Cattleyas about every 6 days since we've had that humid stretch, but winter would be different.

The key thing nobody tells you is that you're not aiming for "moist" - you want the plant to have a tiny bit of stress between waterings. That actually triggers better blooming. Just feel the weight of the pot too; a freshly watered orchid is noticeably heavier. After a week or so it gets lighter, and that's your signal. If you're really unsure, underwater first and adjust. It's much easier to save an underwatered orchid than one that's rotting from constant moisture.
