Plant + symptom guide
Leaf drop often follows a change: light, temperature, watering, pests, or repotting. Timing usually tells you more than one dropped leaf.
For begonia, read this symptom alongside how the plant usually behaves: Begonias can crisp, spot, or drop leaves from uneven moisture, low humidity, direct sun, or mildew-prone wet foliage. Pattern and leaf texture matter.
Ask what changed in the last two to four weeks.
Check whether dropped leaves are yellow, crispy, or still green.
Inspect stems and undersides for scale, mites, or mealybugs.
Check whether spots are dry and sun-facing or soft and spreading.
Avoid letting water sit on fuzzy or textured leaves.
Evergreen diagnosis
Begonias can drop leaves after a move, a cold draft, a missed watering, or a spell of soggy soil. They are expressive plants, and leaf drop is often the first complaint rather than the final verdict.
The key is to check whether the stems and crown are firm. A begonia with firm stems can regrow after shedding leaves; a soft crown or collapsed stem needs faster intervention.
A new home, a brighter window, lower humidity, or a cold trip from the store can make begonias shed older foliage. The plant may be adjusting while the root system catches up.
Keep care steady for a couple of weeks instead of moving it repeatedly. New leaves from firm stems are a better recovery signal than the fate of leaves that were already stressed.
If leaves drop while stems feel mushy or the pot smells sour, the issue is more than adjustment. Begonia roots and crowns can rot quickly in a heavy, wet mix.
Remove collapsed tissue, improve drainage, and consider taking healthy cuttings if the base is failing. Saving a begonia often means preserving firm growth before the rot climbs.
Stabilize light and temperature before making another major change.
Correct watering based on soil feel, not panic.
Isolate if sticky residue or moving pests are present.
