Philodendron: Pink Princess (4")
Light
Providing your pink princess philodendron with enough light is the most important factor influencing the amount of variegation it will have. Choose a location that receives several hours of bright, indirect light.
When grown indoors, the pink princess philodendron can also tolerate a couple hours of direct light, which may help to increase its variegation. If you do not have a location in your home that receives enough light, buying a grow light for this plant is recommended. Without enough light the pink princesses leaves will quickly begin reverting back to green and it will lose its stunning variegation.
Soil
As an aroid, the pink princess philodendron enjoys airy, well-draining soil that is high in organic matter. A mixture of one part standard potting soil, one part perlite, and one part orchid bark is ideal for the pink princess.
Water
Allow the top half of the soil to dry out between waterings and then water well. Usually, this means you will need to water your plant approximately once a week in the spring and summer, and once every 1 to 2 weeks in the fall and winter.
Ensure that your pink princess is never sitting in waterlogged soil as they are susceptible to root rot. As a general rule, it is far easier to overwater your pink princess philodendron than to underwater it so if you are unsure about whether it needs water, err on the side of caution and wait another day.
Temperature and Humidity
The pink princess philodendron does best in warm, humid conditions - although typical household temperature and humidity levels are fine for these hardy plants. Ideally, keep your plant in temperatures between 65 and 79 degrees Fahrenheit (18 to 26 degrees Celsius) and avoid exposing it to temperatures below 60 degrees Fahrenheit (15 degrees Celsius).
