Place Poinsettia in bright indirect light near a sunny window. Strong light helps maintain vibrant colored bracts for longer periods.
Water when the soil surface feels slightly dry. As it's a winter plant and the soil doesn't get dry easily, avoid allowing the pot to sit in standing water to avoid root rot issues.

To encourage color again next season, the plant needs long uninterrupted nights during autumn until winter (Really dark room without any lighting source even it was a room light). This is the secret behind its famous holiday display.
