And here's the same arch when we arrived today:
Right over on its side, pulling the bamboo trellis partway over as well! But, with MG muscle, some big metal stakes, and lots of twine, we got things righted again. A few of the gourds had broken, but we still have plenty of giant ones: I measured one at 46" last week.
We also spent a lot of time tying up Jerusalem artichokes that had crashed down on top of other plants. But really we were very lucky.
