Philodendron bipinnatifidum: cutting back or splitting?
In my workplace we have an old houseplant which I think is a philodendron bipinnatifidum. It's been around for a long time and has no official caretaker now. We water it once in a while, but that's it. Many of its leaves now spill out and drape over onto the floor. Is it possible to cut back or split this plant? There is at least one main stem (or are there multiple plants in this pot?) that has many spent nodes and is curving out and over the edge of the pot -- this is the source of the leaves that are all over the floor. If we cut this, will it grow back? Is it advisable to cut it at all, and if so, where?
You have a couple of options here.
You have two plants in that pot, and could cut off the old woody base from which is growing all of the leaves that are cascading onto the floor. You would still have the younger, upright plant next to it.
If you didn't want to discard the old part of the plant and wanted to try and split it to have two plants, you could take a another soil-filled pot and position it next to your pot. Put the woody stem in good contact with the soil and keep it moist, and hopefully rooting will occur for you over time, which is when you could sever it from the mother plant.
We also think that if you cut that side out of your pot it may try to sprout again but we are not certain.
