Check these first

  1. Examine the spots to see if they are fuzzy or dry.
  2. Check the soil surface for any signs of mold or excess moisture.
  3. Ensure the plant has enough space for air to move around it.

Likely causes

  1. Fungal Leaf Spot

    Possible

    How to tell: Small brown or black spots appear on the leaves, often with a yellow halo. This is caused by high humidity and poor air circulation.

    What to do: Remove the affected leaves to stop the spread. Improve air circulation around the plant and avoid getting water on the leaves when watering.

  2. Water Splashing

    Possible

    How to tell: Small, irregular spots appear after watering. These spots are usually superficial and do not spread rapidly.

    What to do: Water directly at the base of the plant rather than over the top. Use a watering can with a narrow spout to keep the foliage dry.

When to worry

Small, isolated spots are usually cosmetic and not a major concern. If the spots are spreading quickly or the leaves are turning mushy, it is a serious sign of bulb rot.

Stopping it coming back

Keep the foliage dry when watering and ensure the plant is in a well ventilated area.
