Hi everyone, my philodendron gloriosum arrived a few days ago. Unfortunately, it was left outside of the door in around 1 degree Celsius for about an hour since the DHL mailman literally just dropped the parcel and left without ringing. It was in a vase with some water for 2 days and then was planted in soil (I used 1 part pumice+perlite substitution and worm casting each, 2 parts of coco coir and orchid bark each).

There is a big old knode (?) that looks like it had completed died off, this is also where the current two leaves and one new growth is shooting off from, so I planted that together into the soil. Other than that, everything looked fine and the roots are healthy.

When it arrived, there were only a few black spots and some very faint yellowness on one of the leaves, these started to spread to the other leaf on the next day and throughout the course of these 4 days the yellowness is getting more and more distinct and is slowly taking over more surface. Is this just shipping trauma or could it be something more serious? I'm a bit worried that if those two leaves are down then the plant would die off since it won't be able to perform photosynthesis. Is there anything I could do at the moment?

I'm assuming you are somewhere up north. The only thing I could think to add would be humidity. You could use a humidifier or some sort of container to raise the humidity until the plant recovers.

Thank you! Yes, it is next to a humidifier right now and gets a relative humidity of around 50% day round. I know that higher humidity might be even better but I need to be able to breathe since I'm also in the same room hahah. Guess I'll have to wait more patiently for now.

It looks like you'll lose both big leaves, but that doesn't mean the plant won't recover and give you new growth.

I see, so if both of the leaves die before the new growth unfurls I can just keep it in the same pot and water according to its needs, is that correct?
