I picked up a couple 'mainacht' Salvias from the store weeks ago for my front yard area. I don't know if I just hadn't noticed this in the store, or if it somehow picked it up while it sat on my front step away from all the other plants for a couple days (to see if it had any diseases brought home)... but the next day it was covered in powdery mildew. I cut the plant WAY down so it could be aired out and have sprayed it with Neem once a week for the last two weeks. It is due for another spraying now. It still looks like this today:
I don't want to put it in the ground like this as I don't want it infecting the ground area. I also don't want it infecting any nearby plants. Is it possible to completely eradicate this mildew from a potted plant before planting it?
Thanks!
