  • Separate the mother plant from the offshoot roots. Dispose of the mother plant because it can no longer produce a bloom.
  • Examine the root of the plant. Check for any rotten tissues and remove infected or unhealthy areas.
  • The leaves should also be trimmed down to about 3 to 5 inches. This will help the plant establish new growth.
  • Replant your fresh rhizomes in a new bed.
