So this poor old plant, (philodendron) I found it beside a dumpster at my old job. Took it home and it was doing fine. This winter I think it didn't get enough light or water, and lost most of its leaves, then I left it outside overnight (stupid me) and the remaining leaves it had at the top froze. As you can see there were some in the center that made it, and so the plant lives on. I feel so bad, because it looks like it did well for many years. My question is - should I trim off the stalks from where the leaves were growing? Will new leaves sprout from those again, or trim it back to the base?
