Why Is My Spider Plant Dropping Leaves?
Leaf drop is the plant’s response to stress, and a sudden change in light, temperature or watering is a common trigger.
Recent move = transplant shock. Cold draft or hot vent = temperature stress. Soil that swings between soggy and parched = watering stress.

Three things to check, in order
- Cause 1
Sudden environmental change
Moving a plant from a garden center to home, repotting, or even moving it to a new window can trigger leaf drop. Iowa State Extension notes that a sudden change in light intensity causes leaf drop, including a quick move from a bright spot to a darker one.
Fix: Don’t do anything reactive — the plant is acclimating. Keep watering normally, hold any fertilizer, and give it time to stabilize.

- Cause 2
Temperature stress
Cold drafts or hot AC and heat vents can make tropical species drop leaves. Iowa State Extension notes that temperatures below 50°F or rapid temperature swings may harm some plants.
Fix: Move the plant away from the window, vent, or door.

- Cause 3
Watering inconsistency
Iowa State Extension lists soil that is too wet or too dry among the causes of leaf drop. Waterlogged roots rot, and a parched root ball can’t supply the leaves.
Fix: Reset with the finger test: when the soil is dry down an inch or two, water thoroughly and empty the saucer, as Iowa State Extension advises. Maintain the rhythm.
