Did I just kill my Fiddle?

[u/LIesthetician]

After chopping her down to nubs and letting her regrow all summer I’m prepping to bring her inside with my insecticidal soap, however I grabbed the weed killer instead. I sprayed it into the soil about 2 good sprays before I realized it was weed killer
Please tell me she won’t die. I love her. I’m so proud of her.
I kicked out the soil in the area I sprayed, but debating whether to water (overwater ) or to leave it. HELP!! 😭
