Environmental Shock (Temperature or Light Fluctuations)

As a tropical species, sudden exposure to cold drafts or a significant drop in light levels can trigger abscission. This is particularly common when the tree is moved indoors or during seasonal shifts.

Very Common

Fungal Pathogens (e.g., Phytophthora)

Waterborne pathogens like Phytophthora can attack the root system of large Ficus species, causing the tree to lose its ability to support foliage, resulting in sudden wilting and leaf drop.

Common

Nutrient Deficiency (Nitrogen or Magnesium)

A sudden inability to maintain foliage can occur if the soil is depleted of essential macronutrients, though this usually presents with chlorosis before total leaf drop.

Common
