My cattleya orchid started growing these long white roots outside the pot over the past few weeks. They look healthy but I'm not sure if this means something's wrong or if it's totally normal. Do I need to do anything about them?
I had the same thing happen with mine and I was genuinely concerned at first, but it turned out to be one of the best signs I could get. What really helped me was misting those aerial roots a few times a week - they seem to drink it up and it actually improved the overall health of the plant way more than I expected. You can also gently guide them back toward the pot if they're getting unwieldy, or if you're feeling adventurous, wrap them loosely in sphagnum moss to give them extra moisture without cutting them off. The fact that yours are white and actively growing means your cattleya is genuinely happy and just wants more humidity than the potting medium alone can provide.
Don't cut them off - that's the mistake most people make. Aerial roots are completely normal for cattleyas and actually a sign your orchid is healthy and thriving. Those white roots absorb moisture and nutrients from the air, which mimics how they grow in nature clinging to trees in the rainforest. You can leave them alone, or if they bother you aesthetically, you can gently guide them back into the pot or let them be; they won't hurt anything either way.
Your cattleya is just doing what it was evolved to do - those aerial roots are actually trying to access the humidity and moisture in the air, mimicking how these orchids grow on trees in tropical forests. The fact that they're white and healthy-looking is a great sign. You don't need to do anything special with them, but here's the thing most guides skip: if they're bothering you aesthetically, you can gently guide them back into the pot or alongside it using a soft tie or stake, rather than removing them entirely. They'll keep trying to reach outward though, so it's more of a cosmetic redirect than a permanent solution.
What's actually useful is paying attention to what triggered this growth. Aerial roots usually develop when orchids want more humidity or air circulation than the potting medium is providing. If you live somewhere dry, your cattleya might be telling you it'd appreciate occasional misting or a spot with better air movement. You could also try repotting into slightly larger media (bark chips tend to dry faster than sphagnum) if you're watering frequently. The roots themselves are harmless - they're a feature, not a bug.
Those aerial roots mean your cattleya is happy and actively growing, so leaving them be is the right call. The one thing people sometimes overlook is that while misting helps, those roots also need decent air circulation or they can rot if they're constantly wet and stuck against something - make sure they have some breathing room and aren't pressed against the pot or a wall. If they dry out completely that's fine too, they're surprisingly forgiving, but they work best when you occasionally give them a light mist along with the rest of your plant.
