Ideally, philodendrons like most aroids, thrive in medium to bright, INDIRECT light. Direct sunlight should be avoided as it will burn the leaves. Most philodendrons will tolerate some lower light conditions, but growth will be slow or stunted.
Water and Soil
Philodendrons like to be watered frequently but do not like to stay wet or have “wet feet”. The roots will rot! Water when the top layer of soil is just beginning to dry. Create your own aroid mix out of loose friable material. Use about 40% perlite in this mix with NO bark. Bark holds too much water and will cause rot in your philodendrons.
Temperature and Humidity
Philodendrons, like most aroids, prefer a warm room-temperature setting between 70 and 95 degrees F. High humidity is ideal, however they are fairly tolerant to a wide range of conditions once acclimated. Philodendrons become extremely unhappy below 50 degrees F. Frost will kill this tropical plant so make sure to protect them in the winter months and take them inside if they are on your patio or deck.
