repot retrain philodendron?
I've had this plant for decades but I haven't attended to it for several years.
I'd like to keep the entire plant, put it in a new pot, and help it grow into a more pleasing shape with more leaves. Right now the entire bottom third is a tangle of brown root shoots.
I remember years ago encouraging them to reroot by pointing them down into the soil. Back then the pot was wider than the green part of the plant. But after so much neglect now the roots have formed almost like a loose trunk for the leaves. .
How can I make this plant pretty again? Is a post or a trellis better? Do I get a really deep pot and bury half of what's now above ground? Do I just take a big cutting? I don't see how to do that, exactly.
