Brown tips or crispy edges
Why does my Moth orchid have brown, crispy tips?Phalaenopsis spp.
Brown, crisp tips and edges on a Moth orchid are the plant telling you its environment is a little too harsh or dry. The pattern points to the cause.
Dry air (low humidity). Raise humidity with a pebble tray or humidifier nearby — skip misting directly on the leaves, which can encourage rot on this plant.

What's causing it
Dry air (low humidity)
How to tell: Just the very tips and edges go brown and papery while the rest of the leaf is fine — most common in winter with the heating on, and Moth orchid prefers 50-70% humidity.
The fix: Raise humidity with a pebble tray or humidifier nearby — skip misting directly on the leaves, which can encourage rot on this plant.
Inconsistent or under-watering
How to tell: The bark mix dries out hard between waterings, so the tips — the last to get water — crisp first.
The fix: Water more evenly: check the bark mix regularly and don't let it go completely bone dry, then soak thoroughly.
Tap-water salts (fluoride/chlorine)
How to tell: Sensitive plants (calatheas, dracaenas, spider plants, prayer plants) brown at the tips from minerals in tap water.
The fix: Switch to filtered, distilled, or rainwater, and flush the pot occasionally to wash out built-up salts.
Fertiliser burn
How to tell: Brown tips appear with a white crust on the surface, usually after feeding too often or too strong.
The fix: Flush thoroughly with plain water and feed less often, always diluted.
Too much direct sun
How to tell: Dry brown patches or scorched edges show up where strong sun hits the leaf — Moth orchid is medium / indirect light, not a full-sun plant.
The fix: Move it back from the glass into its medium / indirect light range.

Keep humidity up with a pebble tray or humidifier rather than misting the leaves, water before the mix goes bone dry, and feed lightly.
Common questions
Should I cut the brown tips off my Moth orchid?
You can — trim them with clean scissors, following the leaf's natural shape, but leave a thin sliver of brown rather than cutting into green, which just re-browns. Cosmetic only; fix the cause to stop new tips browning.
Should I mist my Moth orchid to fix brown tips?
Better not to — misting this plant's leaves directly can invite rot or spotting. Raise ambient humidity with a pebble tray or humidifier near it instead, without wetting the foliage.
