Leaf Drop
Sudden or excessive leaf drop can be alarming. It is often a stress response to environmental changes.
可能原因
Environmental Shock
Why: Moving a plant to a new location with different light, temperature, or humidity can trigger leaf drop.
Signs to check: Leaf drop began shortly after moving or purchasing the plant, leaves fall while still green.
Overwatering
Why: Excess moisture stresses roots, causing the plant to shed leaves it can no longer support.
Signs to check: Soil is consistently wet, leaves yellow before dropping, lower leaves affected first.
Temperature Drafts
Why: Cold drafts from windows, doors, or air conditioning can cause rapid leaf drop.
Signs to check: Plant is near a door or drafty window, leaf drop is sudden and widespread.
Low Light Adjustment
Why: A plant moved from bright to dim conditions may shed leaves it cannot sustain with less light.
Signs to check: Interior leaves drop, plant was recently moved to a darker spot.
