Why are there spots on my Pineapple Lily leaves?

It is less common for Pineapple Lilies to develop spots, which are usually caused by hungry pests or fungal issues from high humidity. Check the undersides of the leaves for small insects first.

Check these first

  1. Look for slime trails on the leaves or the soil surface.
  2. Check the undersides of leaves for small pests.
  3. Observe if the spots appear after you have watered the foliage directly.

Likely causes

  1. Slugs and Snails

    Most likely

    How to tell: You will see irregular holes or chewed edges on the leaves, often accompanied by shiny slime trails. They are most active during damp, cool weather.

    What to do: Hand pick the pests off the plant in the evening when they are most active. You can also place copper tape around the pot or use an organic slug bait.

  2. Fungal Leaf Spot

    Possible

    How to tell: Small brown or black spots appear on the foliage, often with a yellow halo. This is caused by water sitting on the leaves for too long.

    What to do: Remove the affected leaves to stop the spread. Water only at the base of the plant to keep the foliage dry. Improve air circulation around the plant to help it dry out faster.

When to worry

Worry if the spots are spreading rapidly and causing the leaves to wilt. Minor cosmetic damage from a single slug is usually not a threat to the plant.

Stopping it coming back

Keep the area around your plant clean of debris and water the soil directly rather than overhead.

Questions people ask

Can I use neem oil on the spots?
Yes, neem oil can help manage fungal issues and deter pests. Apply it in the evening to avoid burning the leaves in the sun.
Are these spots contagious to my other plants?
If the spots are fungal, they can spread through water splashes. Isolate the plant until the issue is resolved.
