Plant + symptom guide
Brown tips usually build after repeated small stresses. Separate dry air and salts from underwatering, wet roots, and pest damage.
For calathea, read this symptom alongside how the plant usually behaves: Calatheas curl and brown from dry soil, low humidity, mineral-sensitive water, heat, cold, or pests. They prefer steadier moisture than many common houseplants.
Look for white crust on the soil or pot rim.
Check whether tips worsen near vents, heaters, or hot glass.
Inspect whether new leaves are forming cleanly while old tips remain brown.
Check whether leaves curl during the day and relax later.
Inspect undersides for mites before blaming humidity alone.
Evergreen diagnosis
Calathea tips brown easily, but the cause is usually cumulative rather than one bad day. Mineral-heavy water, uneven moisture, dry air, hot airflow, and mites can all show up first at the thinnest edge of the leaf.
The old brown tip will stay brown. The useful question is whether the newest leaves are opening clean and whether the brown line is widening after each watering cycle.
A calathea watered with mineral-heavy tap water may show white crust on the soil or pot rim before the leaf edges look worse. The same plant may also crisp if it is allowed to dry fully between waterings.
Switching to filtered, rain, or distilled water can help, but only if the potting mix also stays lightly and evenly moist. Cleaner water will not offset a root ball that repeatedly collapses dry.
Fine pest damage can look like ordinary tip burn until the leaves turn dull and stippled. Calathea undersides give mites a protected place to feed, especially in warm rooms.
Use bright light along the midrib and leaf edges. If you find webbing or moving specks, handle pest pressure first. If the plant is pest-free and growing, trim only the dead tip edge and improve consistency.
Trim only dead brown tissue without cutting into healthy green tissue.
Water thoroughly in a draining pot instead of giving frequent small sips.
Move sensitive plants away from vents and harsh heat.
