Your Monstera Adonsonii plant will cope with a variety of lightings, but it will shine its brightest when it’s kept in lots of bright, indirect sunlight. This plant prefers well-draining, organic soil. If the soil is too soggy and wet or too dry and sandy, you run the risk of root rot or dehydration. The best time to water your philodendron is when the top 1/3 layer of soil (i.e. top 1/3 of stick) is dry. The soil should never be drier than that though. Your plant will grow well in moderate temperatures, usually anywhere from 60°F to 80°F (15°C to 26°C). There’s no specific fertilizer that’s better than another for this type of plant. You can choose from a premium liquid fertilizer, a balanced houseplant food or even a seaweed based organic fertilizer.
SOIL: Here is the formula I love and use for my plants:

* 20% orchid bark
* 40% perlite
