Why your staghorn fern has brown tips or spots
Good news — brown tips on a staghorn fern are cosmetic more than catastrophic. They usually mean too much direct sun, low humidity, or mineral buildup from tap water. The plant's fine; it's telling you something in its environment is off.

Why are the tips of my staghorn fern turning brown?
Brown, crispy tips almost always come from too much direct sun, low humidity, or mineral buildup from tap water. The leaf edges are the first to show stress because they're the farthest from the roots.
Should I cut the brown tips off?
You can trim the brown parts off to tidy it up — follow the natural shape of the leaf so it doesn't look hacked. But fixing the cause matters more than the trim, or new tips will just brown again.
How do I stop my staghorn fern getting brown tips?
Address too much direct sun, low humidity, or mineral buildup from tap water. Consistent watering, the right humidity, and flushing the soil occasionally to wash out built-up salts will keep the tips green.
