Overwatering and Root Rot

Excessive moisture in the bulb zone prevents oxygen from reaching the roots, causing them to decay. As the root system fails, the lily can no longer support its foliage, leading to sudden wilting and leaf drop.

Very Common

How to confirm: Gently dig up a portion of the bulb to check if it feels soft, slimy, or smells of decay.
