I don't understand

My trees are all turning to a crisp. They're watered plenty. Roots seem to be alright too...
What's going on!?
I am treating for fungus gnats. Intensely. They're driving me insane.
So I have neem oil, and peppermint in the spray bottles. And doing mosquito dunk water once a week-ish.
But all of those things I read were fine for my plants #whatshappening #driedup #bonsai #blacklocust #pigeonpea #delonixregia #Jacaranda #succulents #pandaplant
It seems like your plants might be suffering from root rot or overwatering, despite your treatment for fungus gnats. The roots in the first image appear severely damaged, which is typical of root rot. Even though you're treating for fungus gnats, overwatering may be contributing to the problem. Neem oil and peppermint sprays are generally safe for plants, but the frequency and water saturation from mosquito dunks might be exacerbating root issues. Consider reducing watering frequency, ensuring the soil has excellent drainage, and trimming any remaining healthy roots. Repotting with fresh, well-draining soil may help salvage the remaining healthy portions.
What kind of soil are they in, and how often do you water them? Do they get any sun or are they under grow lights? If fungus gnats are a problem, I usually recommend adding springtails to the soil. Both eat the same fungus in the soil, but springtails won’t fly or damage roots, and in my experience, they outcompete the gnats.

Depending on what kind of trees you have, the soil type, and where they’re located, it may be that they aren’t able to dry out enough between watering, or there may be something else going on.
