Whether you are growing Areca indoors or outdoors, you have to follow the following instructions:


Areca plants grow best in high humidity. If you are growing it outdoors, then that’s not a problem, but indoors you have to make sure that the air is not dry, because if it is, the leaves will turn brown. Areca plants can grow at normal room temperature. If the air inside is dry, place your plant in a tray with pebbles and water. The evaporation of water prevents dry air and prevents your plant from dying.


Areca plants are susceptible to low temperatures. It needs a temperature between 18-25°C. While growing, ensure that the temperature never drops to 10oC. If you are growing it indoors, keep it away from air conditioners or any region where the temperature is low.

And while growing outdoors, don’t keep it near doorways because the temperature is generally cold around doorways. Protect your plant from sudden temperature drop because it will bring dark spots on the leaves.


Areca palm needs bright sunlight for its growth. It is a part-shaded plant that needs light but not direct sunlight. If exposed to direct light, the leaves will turn yellow/brown, and your plant will be dead. While growing it outside, keep it in shady places, while indoors, place your plant in a room where bright sunlight comes from the southwest facing window, and filter the light by covering windows with curtains, preventing your plant from direct sunlight.


Your plant will be happy outdoors in slightly acidic soil. If you are growing it indoors, then keep it in soil with excellent drainage. If the drainage is poor, it will lead to waterlogging, and the leaves will turn yellow.

To lower the PH of the soil, add some sand, peat moss, and bark mixture. After every three years, re-pot it to remove old soil.


Areca grows best in nutrient-rich soil; if any major salt is missing, such as magnesium and iron, it will not show proper growth. That’s why it is highly recommended to add weak liquid fertilizer during the growing season.


If you want your Areca plant to grow perfectly, then avoid overwatering. The best method to water your plant is to let the soil dry. To check this, put your finger in the soil around one or two inches deep. If you feel dry soil, add water. On the other hand, if you feel moist soil, wait for at least two days and test again.

During summers, it needs more water, but make sure that the soil is not too soggy. For good water drainage, add some pebbles at the end of the pot. Don’t use water that contains fluorides. If you are living in a region in which tap water has fluorides, then use distilled water.


It isn’t easy to find Areca plant seeds. However, if you manage to find the seeds, you can germinate them at home. The germination process takes six months if the temperature is over 80° F and in high humidity. Place the seed at a uniform depth. Try to find old seeds because their germination rate is faster as compared to new green seeds.
