Gary, if it doesn't last more than a day, is that still a problem? I'm up to a sunny morning, and no standing moisture remains. I added sand to the original mix of top soil and compost. Maybe I shouldn't worry if it's gone in a day??
Sandy, I was thinking trenching around the bed and/or adding French drains there. Might that be a solution?? We aren't supposed to have rain for another week, but I'm afraid to plant the bed at this point.
