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.

Use the plant's normal watering, light, drainage, humidity, pest, and temperature preferences before treating this symptom as a generic problem.
For begonia, adjust the diagnosis around this plant profile: Begonias can crisp, spot, or drop leaves from uneven moisture, low humidity, direct sun, or mildew-prone wet foliage. Pattern and leaf texture matter.
Check soil moisture below the surface before watering again.
Compare the symptom with this plant's known weak points.
Look for a recent move, repot, temperature change, or pest clue.
Check whether spots are dry and sun-facing or soft and spreading.
Avoid letting water sit on fuzzy or textured leaves.
Stabilize care and avoid stacking several fixes at once.
Use the analyzer if the symptom is spreading or mixed with other signs.
Read the related guides before repotting, fertilizing, or pruning heavily.
