Watering
Water your tree philodendron when the top two inches of the soil are dry. The soil should be consistently moist but never waterlogged. The tree philodendron does not tolerate drought and grows best with consistent watering.

Fertilizer
Plant your Philodendron bipinnatifidum in rich, well-draining soil. This plant does not tolerate acidic or salty soils, so aim for a potting mix with a neutral pH and avoid using too much fertilizer. To make the best Philodendron bipinnatifidum soil mix, combine equal parts compost, perlite, and coir.

Light
If you plan to keep your philodendron bipinnatifidum inside, you want to have it in bright indirect light in a warm area. This is because, in nature, this plant is in a warm sunny area, but the largest tree, philodendron bipinnatifidum, can grow beneath deep shade with indirect sunlight.

Temperature
The flowers are borne throughout most of the year in south Florida, coastal southern California and Hawaii. Temperature: Hardy to 30oF. Prefers mild to warm tropical or Mediterranean climate conditions.

Repotting
With such extreme growth, you should expect your Philodendron bipinnatifidum to need repotting every two years at least. You will see the roots peeking out of the drainage holes and getting crowded, which is the perfect time to repot it. Wait for spring or summer, as this is the best time to repot all plants.
