I've heard Sept. is best fore dividing Iris rhizomes, but HOW do I tell which part of the rhizome is the part that will BLOOM next year? Last years blooms will not bloom again, right? |
When you dig the iris rhizomes you will notice that the new growth is at the ends but that the center in non-productive. Simply break the rhizome ends off and replant them, discarding the old centers. The replanted ends will grow and flower for you next year. |
