The leaf tips are turning brown and the entire plant is quite yellow.
Areca palms are always a lighter green color than most of their relatives.
Where they are a little too yellow, try feeding with a complete fertilizer. Sometimes the yellowing is due to a lack of potassium or magnesium. Where needed these nutrients can be applied separately. The browning leaves may also indicate a lack of water or too little light. Keep the soil moist and give the areca a bright area to produce the best growth.
