Rubber Plant Leaf Spot in South Texas Winter

Fungal Leaf Spot from Cool, Wet Conditions

Yellow spots expanding to brown, curling leaves on rubber tree (Ficus elastica) in winter indicate fungal infection triggered by cool nights and leaf wetness.

Management

• Remove and destroy fallen leaves.
• Reduce watering; let top 3 inches dry between waterings.
• Improve air circulation around the plant.
• Apply copper fungicide if spots spread rapidly.

Natural Cycle

Some leaf drop is normal as the plant adjusts to seasonal change. New growth in spring will be clean if cultural conditions improve.
