Hi Tris,
The wind is certainly a major consideration. For a windbreak use something porous rather than solid, for example Debris Netting. The aim is to reduce the wind speed rather than try to block it completely. A solid break could create more problems with eddies coming over the top which will be more destructive.
I erect mine at about 6′ away from the plants in the path of the prevailing wind.
It also does not need to be a permanent feature. I only put mine up when we get warnings of particularly
gusty conditions.
Don.
