Why Are My Plant Leaves Turning Yellow?
Yellow leaves can come from overwatering, underwatering, low light, pests, or normal aging. The pattern matters more than the color alone.
Read the guidePlant + symptom guide
Brown tips usually reflect repeated stress rather than one emergency. The key is separating dry air and salts from underwatering, wet roots, and pest damage.
For pothos, adjust the diagnosis around this plant profile: Pothos is forgiving, but yellow leaves usually point to wet soil, low light, old leaves, or a root ball that has gone too dry and then been soaked.
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 yellowing is on older inner leaves or spreading through whole vines.
Look for long bare stems that point to low light.
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.

Pothos yellow leaves are usually about wet soil, low light, old inner leaves, dry swings, or pests hiding along the vines.

Curling leaves can signal dry soil, heat, pests, low humidity, overwatering stress, or too much light. The direction and timing help.

Low light usually causes slow, leggy growth and wet soil. Too much light causes scorch, fading, and crisp patches on exposed leaves.
