|Philodendron selloum is a tree philodendron native to the rainforests of Paraguay and southeastern Brazil. Tree philodendron grows best in fairly moist, well drained, fertile soil. It requires little care except occasional grooming should lower leaves become discolored, and watering in times of dry weather. Take care in placing a tree philodendron, though, lest it encroach on walkways or grow too close to buildings; a small specimen will get big!
Philodendrons don't like full sun. Grow tree philodendron in dappled or partial shade. Tree philodendron should get regular watering. Keep the soil moderately moist by watering regularly. In the winter, keep the soil just barely moist. Tree philodendron has thinner leaves than most species in the genus and therefore needs a little more humid atmosphere.
This is one of the hardiest of all philodendrons. Frost may kill the leaves of tree philodendron or even kill the whole plant to the ground, but if the cold is not too severe and if the plant is well established, it will come back when warm weather returns. You can plan to cover your new plant this winter if cold weather threatens. After its first year it should be able to withstand cold temperatures. Good luck with your new philodendron!
