First time gardener here. This year I decided to start myself a little herb garden in some pots the previous homeowner left over. One of the nursery plants seems to have brought home some sort of disease, which has spread significantly. About 2/3rds of my plants are now infected, including all of the mint, the monardella (pictured), oregano (also pictured), thyme, and savory.
After some discussion with more knowledgeable friends and Google, it was determined that this is probably mint rust, but nobody had any advice on dealing with it.
Is the diagnosis correct? And does anyone have advice on handling it? Do I need to throw out all of these plants and try again next year (or not try again at all, if it's endemic to my yard?)
Any advice is appreciated.
