Why Is My Plant Losing Leaves?
Leaves can fall after a change in light, temperature, moisture, or plant health. Note whether the falling leaves are old or new, green or discolored, and whether the loss followed a move, weather change, or visible leaf damage.
What this symptom means
Leaf loss describes what happened, not the cause. A few older leaves, sudden widespread drop, and leaves falling after spots or yellowing need different checks before you change care.
What to notice first
- Old lower leaves versus new growth falling
- Sudden widespread loss versus a gradual change
- Yellowing, spots, crispy edges, pests, or stem decline before leaves fall
- Recent moves, seasonal light changes, drafts, heat, and root-zone moisture

Why Is My Poinsettia Dropping Leaves?
Check the root ball and recent cold exposure before watering a poinsettia that is dropping leaves. A dry, light pot supports a water-shortage explanation; a wet, heavy pot calls for drainage and root checks. Separate falling green leaves from ageing coloured bracts, and inspect leaf undersides if there is stickiness or visible insect activity.
