Why are there spots on my Split Rock?

It is less common for a Split Rock to develop spots, and this usually happens due to physical damage or fungal issues from high humidity. Check the surface of the leaves to see if the spots are dry or weeping.

Check these first

  1. Touch the spots to see if they are hard and dry or soft and wet.
  2. Check if the spots are spreading to other parts of the plant.
  3. Ensure the plant is not sitting in a humid bathroom or kitchen.

Likely causes

  1. Physical Damage

    Possible

    How to tell: The spots are dry, scarred, or look like small nicks and cuts on the surface of the leaves. These often occur after handling or accidental bumps.

    What to do: Keep the plant in a safe spot where it will not be bumped or handled. These scars will not go away, but they will not harm the plant's health.

  2. Fungal Infection

    Possible

    How to tell: The spots are soft, spreading, or have a fuzzy appearance. This is usually caused by poor air circulation or high humidity.

    What to do: Improve air circulation around the plant by placing it in a well ventilated area. Avoid misting the plant and ensure it stays completely dry.

When to worry

Worry if the spots are soft, spreading, or leaking fluid, as this indicates a fungal infection or rot. Dry, brown scars are just cosmetic and are not a cause for concern.

Stopping it coming back

Keep the plant in a dry environment with excellent airflow. Avoid getting water on the leaves when you do water the soil.

Questions people ask

Can I wipe the spots off?
If they are dry scars, they are part of the leaf tissue and cannot be wiped off. If they are fungal, wiping them may spread the spores.
Will the spots disappear when the plant grows?
The spots will stay on the current leaves until they are eventually replaced by new growth. As long as the plant is healthy, the new leaves will be clear.
