Linda,
 
Many many grovels in apology. I was meaning to be making a light-hearted
tease, but I should know by now that even teases can be hurtful...not to
mention they don't come off as intended in e-mail. Now as for "crocking."
 
It is an historic term, but I cannot think for the life of me where I have
encountered it. I have a bunch of books and articles on 18th-c gardening.
Maybe in one of those. I'll try to do some some scouting.
