Fig Tree Leaf Yellowing and Drop: Rust Disease in Humid Conditions

Recognizing Fig Rust

A potted fig with vigorous growth but sudden lower leaf yellowing and drop after 2 weeks indicates fig rust (Cerotelium fici)—a fungal disease triggered by humidity, rain, or overhead watering. It's cosmetic, not lethal.

Why It Happens

Spores germinate on wet foliage. Potted figs in humid conditions with daily watering create ideal environment. The "vented pot" suggests good drainage, but foliage wetness is the trigger.

Management—No Spray Needed

• Stop overhead watering—water at soil level only.
• Improve air circulation around plant.
• Remove fallen leaves to reduce inoculum.
• Wait for drier weather—new growth will be clean.

Fungicides (copper, neem) can protect new leaves but aren't necessary. The tree fruits well despite rust—focus on cultural control.
