At home, the best place for the Pink Princess Philodendron is in front of an east- or west-facing window. This will allow it to see bright sunlight for several hours a day and spend the rest of the time in shade.
Let your plant partially dry out before giving it a good, deep watering. To check the soil, simply use the finger test: If the top 2 inches feels dry, it’s time to water. Pour water over the plant generously until it flows freely out the drainage hole.
If you like things a little more hands-on, you can easily create your own aroid mix. You need a good balance of moisture retention and aeration, and I use this simple formula for remembering how to make it: 4-3-2-1.
Use a balanced liquid fertilizer in a diluted concentration (half-dose is what I aim for) once a month, and never fertilize when your plant looks stressed.
You can encourage new growth points by cutting the stem in between nodes. (A node is a small bump where each leaf meets the stem or vine.) The best time to prune is in spring, right before it starts to grow again.
