Per Frank:

I think an 8 ft fence will keep out any deer but smaller fences will
deter them too. Deer are browsers and will walk along, bump into a
fence and go other wheres. Netting will deter them and cheapest thing
would be wooden posts with netting. It is not necessary to block their
view. The whole garden should be enclosed or deer could just walk
around fenced sections.

Has anybody tried an electric fence? Seems like the cheapest.
