I have a plant that's sadly on the verge of dying from a pest issue, and I'm wondering what I can do with the soil after it's basically dead. Can I reuse the soil for new plants, or do I need to treat it in any specific way to ensure that I don't harm future plants? I'm still holding out hope that my plant might bounce back!

Honestly, it depends on my mood, the type of plant, and what caused its demise. Sometimes I’ll just throw it in the compost, other times I might toss it out or try mixing it with other soil. I prefer to avoid using it for anything important, though. Better safe than sorry!
There are persistent pests and diseases like Fusarium or Phytophthora that can survive in the soil for a long time, so that's another reason to think twice about reusing soil from a sick plant. If you’re unsure, it might be best to avoid the risk.
It really depends on what type of plague affected your plant. Some issues, like tobacco mosaic virus or bacterial wilt, can leave pathogens in the soil for years. If that’s the case, it’s best to dispose of both the plant and the soil. For bacteria-related problems, hot composting might help, but keep in mind that TMV needs serious heat to be eradicated. Otherwise, it’s better to play it safe and toss it all out.
I typically repurpose that soil for something unimportant, like filling low spots in my yard. Just keep it far away from any vegetable garden or delicate plants.
