Living Tree
If you don't want to spend a lot of time digging and you're willing to take risks, you could try spreading hallow around the edges of the jungle as soon as hardmode starts.
It doesn't actually do much to protect the jungle. And by that, I mean it does next to nothing, and the corruption/crimson will have no problems growing past it.Don't worry, the Chlorophyte Ore will pretect the jungle. oh, maybe only underground.
