I checked the mint this morning and it is completely dead to the ground. No sign of any growth coming up. So it looks like we have discovered a selective killer for mint that will help everything else around it. Maybe someone with a mint problem can try it on a control patch. I used 1/2 cup Epsom Salts in a gallon of water and then sprayed it on. None of the other plants I listed have been harmed. The peppers have turned a rich dark green, so they sure like it. Tom
