What I need to be happy in your home:
Light: As members of the philodendron family, Birkins prefer bright indirect light, though they can adjust to medium levels of light as well. Keep them out of harsh direct sunlight, as too much of it can burn their leaves.
Water: Let your Birkin dry out between waterings. Water thoroughly when topsoil is dry, usually once a week. Avoid overwatering, and note that your watering schedule may be less frequent during winter months.
