Also look for soft spots because this is another common iris problem called soft rot. Using a sharp knife, remove any traces of either iris borer damage or soft rot and dispose of these segments. Soft rot spreads easily, so disinfect your cutting tool with denatured alcohol between cuts, to prevent further contamination. If you question how good the rhizome is, just throw it away.
