Aglaonema Sunlight Requirements

Aglaonemas are forgiving plants that can grow under artificial lighting but will grow their best in bright indirect sunlight. Direct light can be too harsh and may burn the foliage. Aglaonemas can grow well under artificial lighting making them popular among interior designers. Generally, the greener aglaonemas can tolerate slightly lower light conditions, and the bright, colorful aglaonemas tend to need brighter light to maintain their coloration.


Best Rooms To Grow Aglaonema

The best location to grow an aglaonema would be in an east- or west-facing window, or another location that gets bright, indirect light. Be sure to give your aglaonema at least 4 hours of sunlight daily. These plants should be kept out of direct sun for extended periods of time because this will burn the plant’s thin leaves. South-facing windows tend to receive the most direct sunlight and may be too bright for aglaonema. Try placing the plant further from the window or adding a curtain to filter the light if a southern exposure is your best placement option.

When an aglaonema plant is exposed to too much light, it will show signs of sunburn. The foliage will begin to crisp and turn brown. Aglaonemas are accustomed to dappled sunlight under tree canopies in their native habitats in Asia. They usually grow in semi-shaded environments that stay humid and warm.

Providing Supplemental Sunlight To Aglaonema

Perfect for offices and other places with little natural sunlight, aglaonemas can handle artificial lighting. Select a species with more green in its leaves to ensure it will absorb the maximum amount of light possible. Under artificial lighting, these plants should receive at least 8 hours of light a day. In natural light like in a window, they will need at least 4 hours of sunlight daily.

Sunlight Needed For Growing Aglaonema Outdoors

If you plan to grow the plant outside, your aglaonema should receive about four to six hours of dappled or filtered sunlight. Direct sunlight will burn this plant and should be avoided. Acclimate your aglaonema to the outdoors by gradually increasing its time outdoors each day to avoid sunburn.
