I soaked mine for 3 days before putting them in the ground. When I get home this evening, I'm going to check to see if they are starting to swell. Everyone else who survived the winter is putting out leaves (today's going to be 70 degs) so they should be doing SOMETHING. If they don't survive, I won't be ordering from them for 2012.
I'm a bit disappointed on how dry they were. I planted them about 2' down and then piled mulch on top of them so that only about an inch of canes are showing.
