Leaf Spot on alocasia frydek

alocasia frydek with leaf spot

What's Happening

Spots are typically caused by thrips (stippling on new growth), edema from humidity swings (burst cells), or overwatering. Bacterial leaf spot (yellow halos) is less common but more severe. Translucent patches often signal edema from high soil moisture + low airflow.

How to Fix It

  1. 1

    Inspect leaf undersides with a 10x loupe for thrips or spider mites

  2. 2

    Isolate the plant and treat with neem oil or insecticidal soap if pests are found

  3. 3

    Cease watering and allow the top 2 inches of soil to dry fully to resolve edema

  4. 4

    Improve airflow with a small oscillating fan to prevent stagnant moisture on leaves

  5. 5

    Remove severely damaged leaves to prevent potential fungal spread

How to Prevent It

Water at the base of the plant to keep foliage dry. Maintain 60-80% humidity but ensure consistent airflow. Use a well-draining aroid mix.
