Plant + symptom guide
Yellow leaves make more sense when you check which leaves changed, how wet the soil is, light level, drainage, and recent care changes.
For bird of paradise, read this symptom alongside how the plant usually behaves: Bird of paradise plants need strong light and room for large leaves. Splits are normal, but yellowing, curling, or brown edges should be checked against light, watering, and drafts.
Check whether yellowing starts on old lower leaves or appears across new growth too.
Feel the soil below the surface before watering again.
Look for a recent move, seasonal light drop, or a pot that stays wet.
Do not treat natural leaf splits as disease.
Check whether the large pot stays wet in the lower half.
Evergreen diagnosis
A bird of paradise may yellow an old lower leaf now and then, especially as taller new leaves take over. Several yellow leaves at once, however, usually means the roots are too wet, too dry, or too crowded to support the canopy.
This plant can look sturdy enough to ignore, but its big leaves are expensive to maintain. Yellowing is the plant telling you which leaves it can no longer afford.
An old lower leaf that yellows evenly while new spears are strong is not a crisis. Let it finish fading, then remove it close to the base with clean pruners.
If newer leaves yellow, or yellowing comes with soft stems and a damp pot, look below the soil. Heavy wet mix can weaken roots before the plant visibly collapses.
Bird of paradise plants often become pot-bound. When roots fill the container, water may run through quickly while the center of the root mass stays unevenly moist.
Check whether the plant dries much faster than it used to or needs water every few days. If so, repotting slightly larger can be more useful than increasing fertilizer.
Pause and inspect before adding water or fertilizer.
Match watering to the plant's dry-down preference.
Move gradually toward better light if soil stays wet for many days.

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

An overwatered plant often looks thirsty. Wet soil, yellow lower leaves, drooping, fungus gnats, and soft stems are stronger clues than one symptom alone.
