Like most houseplants, Philodendron Imperial Red prefers bright natural light. A moderate or medium exposure.
This plant will tolerate higher light but be sure to keep it out of any direct hot sun to avoid sunburn. Conversely, if you have it in lower light, the leaves will stunt and the plant won’t grow too much if at all.
Let this plant go almost 3/4 of the way dry before watering again. They don’t like to go completely dry. On the other hand, sitting in water or keeping them constantly wet will cause root rot.
