Light: Bright filtered/dappled, or bright indirect light. Direct first morning light and direct setting sun is ok, but plant needs to be acclimated.
Water: The plant's specific water requirements depend on its environment! The more humid the environment, the less you'll have to water. The more light you provide, the more water you will want to provide. Assuming you're providing a quick-releasing medium, your plant will appreciate a heavy soak whenever the plant becomes moderately dry. Stick your finger down in the medium and you'll want to water if the tip of your finger is dry. The best time of day to water is in the morning before the sun is directly overhead and before it gets too hot. If you water at night or overwater or don'tprovide enough light for photosynthesis, your plant may transpire - release excess water through the leaf tip. This is the little drop of water you may sometimes see at the tip ofthe leaffirst thing in the morning or late night.
Humidity: 50-80%. You can get this plant to thrive in your ambient home environment, however you will need to properly acclimate the plant for it to be truly happy. You can pick up a moderately priced humidifier online and honestly, any one of them will get the job done. Pushing your plants together to create a "micro-climate" will help raise humidity as well. Also look into creating a "pebble tray" if you have one plant that requires a little more humidity than all the others.
Soil: Light and chunky, quick releasing. Air circulation is not only important for the leaves, but also for the roots as well. Be sure to provide lots of perlite for optimum airflow. We suggest our Aroid Mix, our Aroid mix mixed 50/50 with our special vermicompost mix, or our coco/moss/perlite mix. Of course, the best mix option depends on your plant's specific needs.
You'll find both climbers and crawlers. Some like to stretch out in a pot, while others like to climb as high as they can go. Make sure to provide a "moss pole" or something of the sort for your climbing philodendron to explore!
