This is an easy to care for plant. We recommend fertilizing once a month in spring through summer with a diluted general house plant fertilizer. The Philodendron Billietiae enjoys higher levels of humidity but will tolerate normal household humidity and even dryer than normal humidity levels. It wouldn't hurt to mist this plant occasionally though. To propagate this beauty, simply take stem cuttings and place them in water or soil. We like to rotate this plant about once a month to promote even growth. Wiping down the leaves monthly will help with photosynthesis and keep the leaves nice and glossy.
