Should I cut off all leaves with spots?

Only remove leaves that are more than half damaged. Leaving some green tissue helps the plant continue to photosynthesize.

Can I use a fungicide on my palm?

You can use a copper based fungicide if the spots continue to spread after you have improved airflow. Always follow the label instructions carefully.

Kentia palm: spots, causes and fixes

Likely causes

Leaf Spot Fungus
Possible
How to tell: You will see small brown or black spots often surrounded by a yellow halo on the fronds. This happens when water sits on the leaves for extended periods.
What to do: Trim off the heavily affected leaves with clean, sharp shears to stop the spread. Improve air circulation around the plant and avoid misting the foliage directly.
Overwatering
Possible
How to tell: The spots may appear dark and soft, often accompanied by a general yellowing of the lower leaves. This is a sign that the roots are struggling in waterlogged soil.
What to do: Check the soil moisture and wait until the top inch is dry before watering again. Ensure your pot has drainage holes so excess water can escape freely.

When to worry

Be concerned if the spots are spreading rapidly across multiple fronds. It is normal for an old, bottom leaf to develop a few small spots before it naturally dies off.

Stopping it coming back

Keep the foliage dry and ensure your palm has plenty of space for air to move around it.
