Philodendron Birkin is an easy to care for plant. Average household humidity levels should suffice, but misting or a humidifier to increase humidity may benefit the plant. We recommend fertilizing every month during spring through summer with a diluted general houseplant fertilizer. Propagating via stem cuttings is possible but may be tricky due to the compact growth habit and short stem. If the growing tip of the plant is cut a new growth point should emerge from the stem.
