I was wondering is there a thing you can bury in the ground to stop adventuresome canes from popping up into lawn


If so how deep does the barrier need to be we have a wood plank in the ground but it's old and only goes a halffoot or so

The only underground barriers I am familiar with are metal sheets buried 2 feet into the ground to prevent bamboo from spreading. If that keeps invasive bamboo out, I am sure it would keep most other things from invading spaces, too.

If you have clay based soil, a 12 inch deep (below the soil line) barrier is sufficient. If your soil is sandy, you might need to go 18 inches. Roof flashing is a relatively cheap (and permanent) material to use.
