These were fine until we had a couple of windy days, with wind gusts up to 40 m.p.h, at which point the one on the windward side was blown out of the ground.

Has anyone else tried these? If so, do you have any tricks to keep them from blowing away? I thought of putting up some sort of wind break, like a short fence, on the windward side, which is to the north and west so it wouldn't block the Sun.

Those look about as long as mine but thinner, I use 2 4x8 bricks midway and 3 at each end. I use concrete reinforcement wire to hold it up.
