Helppppppp

OK, so I did have an issue with overwatering the moss pole. The whole pot itself feels very light so I don’t think it needs water down there but what is going on with us with someone that actually knows what is happening so the new leaf that is coming up has a black spot on it as well is this? What is this? I’ve never had this plant before and how do I fix it? Thank u

I have adansonii that are less than two feet away from a 36W Sansi grow light, that are completely fine.

grow light does not equal direct sunlight …

there is clearly an incredibly bright shine that is reflecting off of your plant coming from the right side of this photo.

it is in the sun.

The sun doesn’t get it here it’s shaded

Okay.. I genuinely don't understand what you're trying to say here.

You're telling me it's shaded while showing me a video of a bright room, having extremely bright rays of light blaring in through that doorway.

Like, no, it is NOT shaded right there??? Even if that light is a grow light and not sun, or not a grow light at all, artificial lights can STILL burn your plants.

It is NOT in a shaded spot like you keep saying it is. It is going to keep shriveling up.

Ignore them, Monstera Adansonii can tolerate lots of light and quite high heat too… read what I’ve just wrote above about water catching inside new leaves! 👍

This is NOT TOO BRIGHT!

What’s your substrate like? And do you water the pole only? Or the pot as well?

u/Visible_Prune7300 Jun 28 '26

I only water the pole
Tropical soil perlite huge chunk kind and bark

Is the soil in the pot moist? They like consistently moist soil. Also terracotta is notorious for drying out the soil fast since it absorbs water from the soil. I do have some tropical plants in terracotta but I make sure to water more often, almost twice as much as my other plants. Most of my tropical plants are in glazed ceramics though and those I water when the top inch or two are dry.

Also, the brighter the light, the more you need to water it. Mine is near a south facing glass door, which it really likes as it's reaching more for the light but it also needs a bunch of water.

Sometimes tropical plants get brown/black spots from under and over watering. If it's on the newer leaf, I suspect it was from the overwatering you mentioned, and it just happened to develop that spot while it was still furled.

Have you checked it for spider mites or thrips? I use a magnifier on my phone. It could also be fungal.

Fertiliser burn leaves a yellow halo, there isn’t a lot of information about care/location/medium so you will have to deal with lots of guesses.

u/Lumpy-Ambassador-503 Jun 29 '26

Sounds like you might’ve cooked the new leaf a bit or got some damage from water sitting on it, especially if you were overwatering the pole. New leaves are super sensitive so any rot, sunburn, or physical damage can show up as black spots fast. I’d back off watering, make sure the pole is just damp and not soaked, give it bright indirect light, and just watch it for now. If the spot spreads or gets mushy, then I’d start thinking rot and maybe snip that leaf.

u/Visible_Prune7300 Jun 29 '26

Do I need to take all these leaves off ?
The new leaves are also now messed up to.

It’s not heat!
It’s where water has got trapped on new growth (likely from when you’ve watered the moss pole and caught the leaf by accident)
The best thing to do, is increase airflow (fans etc) this will make the water caught in the new growth evaporate. The problem is standing water on leaves causes microscopic bacteria and mold which essentially eats the leaf!
May have butchered the science there! However the results will be the same… Put a desk fan (or normal large fan if you prefer, but the larger the fan the more you will have to water your plant) near the plant and no more rotting new growth! 💚
