Hi All,

Ive heard of a treatment for mint rust called the warm water treatment.
Could anyone tell me about this? What it involves and how i go about it?

I think you've asked this before and not got an answer.

It's a very long time since I've done anything like this, but IIRC it
involved waiting till the top growth had died (or removing it if it was
badly rusted) and dunking the roots briefly in very hot water to kill
the over wintering rust spores.

This is a very old memory, so don't try this if it matters to you losing
the mint.
