When the prevailing wind blows from the west the portal to the caged garden becomes a wind tunnel, so instead of putting on doors, I built a windbreak with some old lumber.
It’s portable, and can be moved depending on the direction of the wind.

The weather is stormy today, so the windbreak is getting a good test, and it works pretty well. For really bad storms, I’ll have to tie it down so that it doesn’t blow away. This spring it will get a coating of falu red paint.
