Well, what did you do? I would have left them until spring, then dug and moved them, realizing that I was probably going to be sacrificing a year's production.

I have decided to leave them alone and let them recover from the "root pruning" they received! I think they'll be fine and are low enough down the bed that I don't think they will be a problem as long as I remove any shoots in the wrong place. There is enough work to be done to repair the damage over the rest of the yard!
Thanks for asking,

In 2009 I planted blueberries over our new drainfield, as they have shallow roots, so shouldn't interfere with the septic functioning. So far, so good. Northwoodswis
