Philodendron, Cordatum
If the plant receives too little water the leaves will begin to wilt and older leaves often turn a bright yellow. This is why it’s important to thoroughly water the entire rootball. The root system is small compared to other indoor plants. When the plant is over-watered and the soil stays wet the roots will rot. In turn, the leaves begin to wilt and the leaves lose their healthy look and turn to a pale dull green color.
Light
Low to medium, indirect light.
Water
Water the plant when the top 2-3″ of soil feels dry. When watering any plant indoors make sure to water the complete rootball and not just the top surface of the soil. The entire soil mass should be saturated with the excess water poured or drained off.
Fertilizer
For optimum plant health, fertilize with an all-purpose houseplant food April through October, following label directions. For all other months, fertilize half as often.
