Are these spots contagious to my other plants?

If the spots are caused by scale insects, they can easily spread to nearby plants. Fungal spots are also contagious if conditions are damp and stagnant.

Should I cut off all the spotted leaves?

Only remove leaves that are more than 50 percent damaged. The plant still needs its healthy green tissue to produce energy.

Abal Palm: spots, causes and fixes

Check these first

Inspect the undersides of the leaves for tiny brown bumps.
Check if the leaves stay wet for long periods after watering.
Look for sticky residue on the leaves or the floor beneath the plant.

Likely causes

Scale Insects
Most likely
How to tell: You will see small, brown, bump like insects clustered along the veins or undersides of the fronds. They often leave behind a sticky residue called honeydew.
What to do: Gently wipe the leaves with a soft cloth dipped in a mixture of water and a few drops of mild dish soap. For heavier infestations, apply neem oil spray once every 7 days until the insects are gone.
Fungal Leaf Spot
Possible
How to tell: These look like small, dark, or water soaked circles that may have a yellow halo around them. They usually develop when the leaves stay wet for too long after watering.
What to do: Prune away the most heavily affected fronds to improve airflow. Avoid overhead watering and ensure the palm is in a spot with good natural ventilation.

The list above covers the usual causes. Pocket Botanist looks at a photo of your actual plant and tells you the likely cause, how serious it is, and what to try first. Identification and a health check are free.

When to worry

Worry if the spots are spreading rapidly across multiple fronds or if the palm shows signs of wilting. A few small, older spots are usually just cosmetic and not a cause for alarm.

Stopping it coming back

Water at the base of the plant rather than over the leaves to keep the foliage dry. Maintain good spacing between plants to encourage steady airflow.
