The message
from "Paul D.Smith" contains these words:

Any tips for handling rhubard crowns? Should I prepare the ground in any
special way before planting etc?

Dig a BIG WIDE hole for each crown and fill it with well rotted muck
and compost-heap contents, plant the crown in it and water in well. Each
year, mulch well with more muck. It's a hungry root, supporting huge
annual growth above ground, so you can't overfeed rhubarb. The taste and
tenderness difference between well-fed rhubarb and unfed rhubarb is well
worth the effort.

Janet.
