Did I just Kill my Philodendron?!
So, My philodendron that I keep at work had become infested with fungus gnats-- gross. So I took him home yesterday to basically dump the soil, clean the roots and re pot with soil that I known isn't buggy. Problem is, we're like in arctic temps right now. I got it to the car, got it out, dumped the soil and immediately went inside. When I re-potted, i rinsed the roots with lukewarm water and the soil i re-potted with wasn't cold. However, today, the leaves are wilted and inside the veins you can see brown. (see pics). A few of the stems towards the main part of the plant have started to turn yellow as well.
He's back in his spot at work (which meant having to go outside again for about a 5 minute car drive to work).. but I'm wondering if the damage is already done.
