Black or Rust-Coloured Spots on Aloe Leaves

Commonly affects: Aloe vera (Aloe Vera)

Small black, brown, or rust-coloured raised or sunken spots appear scattered across leaf surfaces, sometimes called 'aloe rust'.

Potential Causes

  1. 1A fungal condition sometimes referred to as aloe rust, favoured by high humidity and overhead watering
  2. 2Poor air circulation prolonging leaf surface moisture
  3. 3Overcrowded plants restricting airflow

Solution Steps

  1. 1Remove severely affected leaves
  2. 2Improve air circulation around the plant
  3. 3Water at the base rather than overhead
  4. 4Apply a fungicide if the condition is spreading significantly, though it's often largely cosmetic and manageable with better care alone

Prevention Tip

Aloe rust is largely a cosmetic fungal issue driven by excess humidity and overhead watering — improving airflow and watering habits usually controls it.
