Houseplant dropping leaves? Build a timeline first
Finding a leaf on the floor can make every part of the care routine feel suspect. One fallen leaf does not identify one cause or predict what the plant will do next. Before watering, feeding, pruning, moving, and repotting together, build a Leaf-Drop Timeline you can compare.
1. Record where the leaf came from
Save whether it came from the lowest older growth, newer growth, the inner canopy, one stem, or one side. Photograph the likely former position without pulling or shaking another leaf to make a comparison.
2. Save the before-drop appearance
Use an earlier photo when one exists. Record whether the leaf was green, yellowing, curling, crisp, spotted, or physically damaged. These are visible details, not proof of overwatering, underwatering, pests, or disease.
3. Date and count the pace
Write down each drop and include days when no leaves fall. One older leaf this week creates a different record from several leaves in a day. A dated count is more useful than trying to reconstruct the sequence later.
4. Map the whole-plant pattern
Keep the pot, stems, nearby leaves, and room in one frame. Record whether change is limited to lower leaves, new growth, one branch, one side, or the whole plant. The wider view gives the fallen leaf context.
5. Add recent care and room changes
Record watering and drainage, a room or window move, heating or cooling, a cold draft, transport, fertilizer, repotting, and visible pest clues. Do not assume one recent event is the cause; use the timeline to compare what changed.
Choose one cautious next step
Correct one clear issue at a time and repeat the whole-plant photo from the same position. Avoid stacking water, fertilizer, pruning, repotting, and a new location from one fallen leaf. Seek qualified local help when leaf loss is sudden or widespread, stems are collapsing, a severe pest pattern is visible, or safe inspection is unclear.

Keep the comparison useful
Pair the timeline with the broader sick-houseplant first pass, use visible pest clues when relevant, and keep a repeatable plant recovery log while you compare change over time.
