It's enough to keep critters away yea.
Something like that (36" tall I'd recommend, except the taller version listed there has 2" holes so mice may get in):

Bury it 8"-12" deep and fence around each plant. The trek with the caging isn't so bad, you can use the cage to bat away branches and other forest matter on your way to the site. To cut the fencing you just need a hand pruner. The roll is kept together with a wire that wraps around it, you can keep that wire and use it to wire closed the fencing around each plant. The cage doesn't need to be wired together to intensely though, just enough so that it won't open up obviously, burying it 8"-12" should keep it in place more or less anyway
