It's a clear sign that your areca palm needs more water.
Check the top layer of soil with your hand and if it's dry, water your palm.
Water in stages; pour one mug at a time until it drains from the bottom hole.
Watch for leaf changes; yellowing or drooping may signal over or under watering. Adjust accordingly.
Mist or shower your areca palm to boost humidity and support healthy growth.
