For all its delicate beauty, growing Monstera adansonii is fairly straightforward. Plant it in a pot with drainage holes using a standard potting soil that contains peat. (Peat helps to trap moisture without becoming waterlogged.) It will look best in a hanging basket or in a pot on a high shelf or somewhere else where its trailing vines can be shown off to advantage without getting in the way. Put the plant near a window where it will receive bright, but indirect, sunlight. Trim the vines as needed if they start to look scraggly to encourage new growth.
Watering is the trickiest part of caring for Monsteras. They like consistently moist soil but don’t want to be soggy. They also like high humidity, which can especially be a challenge in winter, so consider using a humidifier. Yellowing leaves are a common issue and indicate that something about your watering schedule is off. Test the soil with a finger before you water: at least the top inch should be dry. On the flip side, make sure you’re not giving it so much water that the top layer of soil remains wet for several days at a time. Watering once a week should do the trick, though you might need to experiment with frequency based on the temperature and humidity in your home.
