I was led to believe that to overwinter Cosmos Chocamocha you treated them like Dahlia's? I recently potted up last years corm and on inspection today found the corm had rotted. A new corm that I bought this year and potted up at the same time is growing well. Should I have treated it as my Canna Lily and kept it in slightly damp soil in a frost free place over winter? The Canna Lily is now growing strongly.

I was under the same impression and on inspecting mine today found it had rotted away completely - very disappointed as will have to buy again. I followed the instructions to the letter so don't know why it failed to survive but will have another go at keeping it alive over next winter. Good luck
