2nd rescue attempt
Ok, earlier this year, I brought back an impatien from the brink that I'd gotten from a neighbor(my first impatien). A few neighbors in the building asked me to put it in our community room for the winter instead of keeping it in my apartment, and I agreed as long as they would take care of it, as I don't spend much time in the community room. Well, I wandered in there earlier and found the plant with one puny bloom, wet soil, rubbery stems hanging over the pot sides, and loaded with spider mites. Needless to say I confiscated it. I put it in my bathtub, sprayed it with Safer's soap(it's all I have), and flushed the soil with H2O2 laced water. Was this ok? Is there anything else I can do? Thanks in advance for any help.
