How do you get bamboo culms into the ground as supports?

[throwaway]

Long story short I have some evil bamboo on my property that I haven't had the chance to eradicate (yet). The culms are pretty thick and sturdy, so I took a few down and cut into 8ft lengths. My hope is to get them ~2 feet into the ground and string some twine or nylon between to support a wall of tomato & friends. Trouble is I can't imagine how to get the bamboo 2 feet into the ground. I figure a post driver would shatter the culm. I saw one mention of a dead blow hammer on a search, but how big/heavy should that be? Or do I shovel a 2 foot hole, put culm in hole, hold upright, and fill back in? Or is there a better way? Also, any suggestions for attaching the string to the culms? I was thinking about lashing, but drilling and threading might be easier/stronger? I probably need 6-8 posts, so the solution doesn't have to scale up!

Lastly, if you have any practical uses for dug up rhizomes I am all ears
