Why does my plant have brown leaf tips and edges?
Brown, crispy leaf tips usually mean the leaf ran short of water at its far edge — from dry spells between waterings, dry indoor air, or roots that can't keep up. Brown edges after months of feeding can also mean fertilizer salt buildup. The brown tissue won't turn green again; the goal is stopping the spread.

The differential: five causes of brown tips
| Cause | What it tends to look like | What to do today | What to change this week |
|---|---|---|---|
| Inconsistent or under-watering | Crisp brown tips across many leaves; soil swings from bone-dry to soaked; pot feels light before watering days | Check the soil — if it's dry a few centimeters down, water thoroughly until it drains | Even out the rhythm: water when the top few centimeters feel dry, not on a fixed calendar |
| Dry air (low humidity) | Tips and thin leaf edges brown first, especially on thin-leaved tropical plants; worst near radiators and vents in winter | Move the plant away from heat sources and drafts | Group plants together or stand the pot on a pebble tray with water; misting helps only briefly |
| Fertilizer or salt buildup | Brown edges plus a white crust on the soil surface or pot rim; a plant that's been fed regularly for months | Nothing urgent | Flush the pot: water slowly until several times the pot's volume has drained through, then feed at half strength, less often |
| Water quality | Tip burn on sensitive species (dracaena, spider plant, calathea, prayer plant) despite a steady routine | Nothing urgent | Try filtered water, or tap water left out overnight, and see if new leaves come in clean |
| Sun or heat scorch | Brown, papery patches on the sun-facing side, often after a move to a brighter spot or against hot glass | Pull the plant back from direct midday sun or hot windows | Reintroduce brighter light gradually over a couple of weeks |
Can I trim the brown tips?
Yes. Trim with clean scissors, following the leaf's natural shape, and leave a hair of the brown margin rather than cutting into green tissue — a fresh cut into live leaf just browns again. Trimming is cosmetic; the fix is whichever cause the differential points to.

Brown-tip questions
Will brown tips turn green again?
No — browned tissue is dead and stays brown. Trim it for looks if you like, fix the cause, and judge success by the next leaves that grow in.
Does misting fix brown tips?
Not really. A mist raises humidity for minutes, not days. Grouping plants, a pebble tray with water, or simply moving the plant away from radiators does more for dry air than misting ever will.
Is it the tap water?
Sometimes, for sensitive species — dracaena, spider plants, calathea and other prayer plants are the usual suspects. If your routine is steady and tips still burn, try filtered water or tap water left out overnight, and watch the next new leaves.
