Plant Doctor Philodendron Cordatum Plant Care Guide:
The Philodendron Cordatum prefers bright, indirect sunlight but can tolerate more moderate light situations. Too much light will pale the leaves or burn them.
Water once a week and allow the soil to dry out slightly between waterings. They will wilt slightly when in need of water and will perk up once re-hydrated. If the leaves turn yellow, you are over-watering.
