The little path is free! The pile of irises is on the left, the pile of saxifrage is by the gate.
So I got out the fork and the spade and started at it. At first I couldn't get the irises to budge and I almost gave up. But after trying a couple of things, I finally figured out how to dislodge them. It took a couple of hours, but I ripped out the plants and their roots and made two piles: one of irises for relocation and the other of elephant ears for getting rid of. I ripped out a fair amount of ivy as well. Ken spent a morning trimming the ripped-out irises and replanting them in a plot behind the shed.
