Rhubarb is most successfully transplanted early in the spring before any growth has started.  The plants can also be transplanted at other times but it will be more difficult.  The next best time is in the early fall, followed by summer being the most difficult.

Follow these steps to transplant rhubarb:

  1. Dig up the entire plant.  Try to get as much of the root system as possible.
  2. Divide large plants into several sections.  Each section should have 2-3 buds and a good root section.
  3. Replant the original plant back at the same height as it was when you started.
  4. If the new section must be stored for a day or two, be sure to keep it moist.  Roots should not be allowed to dry out.
  5. Plant the new rhubarb section in a sunny location with fertile, well-drained soil.  The section should be planted at the original height or place the buds 1.5″ – 2″ below the soil surface.  Water with a mixture containing a root stimulant like Earl May Plant Start.  Adding a good layer of shredded bark will help retain moisture during the summer months.
  6. For best results, new plants should not be harvested until the third season.  In the third season, harvesting for 4 – 6 weeks until mid-June is recommended.
