Watering:
Keep your aglaonema plant’s soil just barely moist—but not wet—and avoid allowing the soil to dry out completely. Generally, it will need watering more frequently in the spring and summer and less in the winter, so check the soil moisture regularly.
Fertilizer:
Feed your aglaonema with houseplant fertilizer diluted to half strength every four months or so.
Re-potting:
When your plant’s pot becomes overcrowded, transplant it into a container one size larger with fresh soil, during the spring or summer when the plant is actively growing.
Temperature:
This plant likes the heat, so make sure that you place it in a warm spot, ideally with nights in the 15 degree Celsius range and days ranging from 23 to 30 degree Celsius.
