Likely causes
Mineral accumulation
PossibleHow to tell: The very ends of the roots turn brown and brittle rather than staying green and firm. This happens when salts from tap water build up on the root surface.
What to do: Switch to using distilled water, reverse osmosis water, or collected rain water for all misting and watering. Flush the roots gently with pure water once a week to wash away any remaining mineral deposits.
Low humidity
PossibleHow to tell: The roots look shriveled and dry, and the tips lose their vibrant green color. This occurs when the ambient air moisture drops below 70 percent.
What to do: Increase the humidity around your orchid by placing it in a terrarium or near a humidifier. Aim to keep the humidity between 70 to 90 percent at all times.

When to worry
Be concerned if the browning spreads rapidly toward the center of the plant or if the roots become mushy. It is normal for a very old root to eventually dry out as the plant grows new ones.
Stopping it coming back
Always use pure water and maintain high, consistent humidity to keep the root tips healthy and active.

Questions people ask
- Can I use tap water if I let it sit out?
- No, letting tap water sit does not remove minerals like calcium or magnesium. You must use distilled or rain water to avoid root damage.
- Will the brown tips turn green again?
- No, once a root tip turns brown and dies, it will not recover. Focus on keeping the new growth healthy.
