Hello and rusty mint

Hello everybody, I've been lurking for a while and enjoying the chat and advice given.
In the middle of renovating a very neglected (by us) garden really enjoying buying new plants checking the growth of them daily. Husband this evening actually said "Ville de Lyon has reached the top of the trellis" - we had a glass of wine to celebrate.
Loads of questions but the first is why has a newly bought pot of mint - nothing special just spearmint I think - got what looks like rust spots all over its leaves?

 

Hi, hope you enjoy the company!
Remove all the affected leaves and spray with fungicide if you use such things. If you let it get a hold it will kill the plant. It might have brought the infection wih it.

 

Name of a fungicide please Liz? Could it spread to other plant?

 

Anything containing sulphur, at the garden centre. It would spread to any member of the mint family [Lamium] but I don't know if it's the same as rust on other plants, like hollyhocks.

 

I have got ville de lyon mine also has reached the top of the trellis cant help you with the rust on the mint i am hopeless at keeping mint always seem to die when i get them. bought one each year i have given up on them, got basil off my next door neighbour fingers xxxxx it is fine

 

Thanks Liz
