Solved Unknown bumps appearing on peppermint leaves and stems!

Just an update, I decided that it was best to toss the main plant, but prior to doing that I took a few cuttings, am propagating in water and intend to quarantine before replanting once I have ensured that I can't see any signs of rust. Fingers crossed!

 

I guess its worth a try AOG but I would not keep anything that was disease affected. For the small cost of a clean replacement I would get rid of the old plant, cuttings as well.
There are so many pest and disease problems around now that I thoroughly check all plants introduced here

 

I think you may well be right Verdun, I'll give it a shot but at the first sign of any rust papules they will be destroyed aswell. I've learnt my lesson and will be extra vigilant from now on when purchasing new plants!

 

I quite agree on this one mate

 

Hi AOG, sorry to hear throwed it away...it's a shame when it comes to plants we like
