Areca palms like a warm spot in bright, indirect light. The secret of success with an areca palm is to get the watering right – the soil needs to be moist but not soggy. Areca palms also like humidity, so mist the leaves a few times a week or stand on a tray of moist pebbles.
Fertilize areca palm plants with a time-release fertilizer in spring. This gives the plant most of the nutrients it needs for the entire season. The fronds benefit from a micronutrient spray in summer. You can use a liquid houseplant fertilizer that contains micronutrients for this purpose.
They need bright, indirect light from a south- or west-facing window. The leaves turn yellowish-green in direct sunlight.
Indoors or outdoors, this plant does best in average temperatures of 65 to 75 degrees Fahrenheit. It will do fine planted in the garden in regions where outdoor temperatures don't dip below about 50 degrees Fahrenheit.
Areca palm houseplants need repotting every two to three years. The plant likes a tight container, and crowded roots help limit the size of the plant. The main reasons for repotting is to replace the aged potting soil and remove fertilizer salt deposits that build up in the soil and on the sides of the pot.
