Hello! I just potted my mini monstera (Rhaphidophora tetrasperma?) from a cutting. I waited until the roots were about an inch and potted it with a mix of potting soil, some small rocks at the bottom and a small amount of cactus soil (just what I had on hand).

I soaked the soil then placed it about a foot from a western facing window. I know these want indirect light but I don't have a north/south facing window and read online people give it direct sunlight if it's indoors. It got about an hour of direct sunlight in the evening which is when I noticed it was wilting so I moved it away from the sun.

Was it a coincidence and it's just in shock from getting planted or did I burn the leaves? I was sooo excited about this cutting because I wanted one of these for so long and I'm worried now that it won't be viable! help, please!

@Gina1960

we can;t really see what you have potted this into. Is the white pot a cache pot or the real pot?

Hmm @Gina1960 that's a good question. I'm not sure I'm savvy enough to know the difference. But it's a ceramic "pot" that was ceramic on the inside too, I drilled a drainage hole. Attaching a picture

Did you root this in water?

Yes

That is the problem. If you had simply applied a bit of rooting hormone and stuck it into the soil in the pot in the first place, or rooted it on sphagnum moss or dirty moss (sphag mixed with a bit of perlite and potting mix) it would have rooted more naturally and made roots that would be already acclimated to being 'planted' in mix.
Water roots are not that way. They are fragile roots that have never had to contact and grow through a substrate and 'toughen up', and they have never had to search our water through drier pockets of substrate where they would have been highly encouraged to branch a lot (thus making them make 'spoiled rotten' and now your plant will have to try and do all this with newer roots while it tried to support the leaves)

I see, that is very informative and helpful. Thank you so much @Gina1960.

At this point, is there anything I can do to support the plant? Would it help to stake the leaves slightly so they're not up against their own weight? And I wondered about watering--my instinct is to keep the soil moist while it's strengthening but I don't want to cause rot or other issues. Your guidance is very much appreciated.

It would be better if you did not disturb it again. The best thing (although I know this would be hard for you) might be to cut the leaves in half so the plant doesn;t have to support so much leaf material when rooting, but, at the same time, the water roots it has may step up and do the job...but its not an overnight thing. They have to make a sort of different kind of tissue. And one day is not a long time to see great results from potting up a cutting. Its basically in a sort of shock. It needs to get used to its new digs and figure out what it needs to do. And it will.

When you are trying to root plants like these vining aroids, think of it this way.

You are a Rhaphidophora tertasperma growing wild in the rainforest on a tree and you are quite happy. One day, poacher loggers come into your forest and decided to cut down your tree. In the process you get whacked into 1000 pieces and just left on top of the ground.

What are you going to do? Grow legs and walk over to the nearest pond, plop in the water, and root yourself?

No. You are going to lay there on top of the soil, get rained on, maybe animals are going to walk on you. But just by your nodes being in contact with the soil, eventually, you will re-root on your own. It may take time and you may look like hell for a while. But eventually you will pick up where you left off.

Last part being part garden advice and part general life coaching

No. Really. Love the imagery!

Indeed! Thanks for the metaphor, it was a journey!
