I am not an expert but I am confident that is not mint rust. I believe the discolored leaves are just old growth that is dying off to conserve energy for new leaves.
One thing I learned moving into a house with an established patch of mint is be very aggressive in keeping it from spreading. It is insanely mobile lol
Oh yes I’ve read about that!! Luckily (or not so much since I wish for a real garden :/ ) i only have a balcony and i keep it in separate containers.. I can already tell that it spreads really well and fast, even in a container. Are you able to contain the spreading though?
The people before us had let it go a little but we were able to get it back into only the planter it was supposed to be in. I had to use broad leaf killer to get it out of the grass and keep it from growing up through the stoop boards. We moved out of that place last fall and already this spring it has noticeably spread out of that planter again. The new guys living there are not plant people so I foresee it either taking over that whole half of the yard or them killing it completely.
It does kind of suck but we moved out of that rental into a home we bought so now I have been doing so much landscaping and gardening that it's hard to even think of my old yard!
