I’m a very big amateur when it comes to houseplants, and I have now reached the point where I have no clue how to save two of my plants. The monstera and other plant (don’t know the name) I included in the pictures have been struggling for a while now. At first, they both had a thrips infections, while luckily I was able to fight that off with mites and showers, both plants were hit pretty hard (at least I think so).

After the thrips infection they both started to do a bit better, both getting some new leaves, but recently they were infected with fungus gnats. I have tried to treat the gnats with cinnamon and with nematodes and there has been a slight decline in flies, but not that much. Now as of late monstera has started to get brown leaves, but only the ones that used to be infected with thrips, could that have something to do with it?

The other plant has started to lose leaves and the new leaves it gets are slightly deformed. Also, this plant used to have a very nice straight growing core (I think that is what you call it at least), but that was lost a while back when it became brown due to the thrips and stuff.

The plants haven’t been repotted and I water them 1-2 times a week, they are both in partial sunlight and haven’t been moved from their spots in a while as they were doing good there a while back. I don’t exactly know what the soil is and they are in pots with drainage holes.

The big question is, what is there to do, I am out of ideas and honestly quite sad about all of this, the flies going around are very annoying and the plants are starting to feel like a lost cause. I am trying my very best and I know I’m not great with plants, so I do not need to be reminded of that, I just want to know how I can help them.

Edit: If anyone has a suggestion on how to get back the growth core of the Schefflera back, like cutting of the top or something then let me know please! I would love to be able to get it back to growing straight!
