This is one of two giant philodendron plants that I had in my apartment. I brought it to the office one day last fall to spend the winter in Martha's office, and it had such a great visit that it completely outgrew its container and needed to be divided and re-potted. I hired Christy Dailey, a local urban garden designer, to come in and help with the situation.
Christy started out as a gardener, and now works designing and planting outdoor spaces as well as rooftop and terrace gardens in Manhattan and Brooklyn. She is a great reference for all things planting and potting, and she often helps us with important plant or garden-related questions and projects.
Philodendrons, which are native to southeastern Brazil, typically grow to be quite large, but it is not at all easy to separate them. In fact, it can severely damage the plant. Check out my photos of Christy's process, but don't try this at home!
