I'm thinking about using vetiver as an outside border of my
land, with a border of bamboo inside of that, on the west + north + east edges. I have 1 acre which I will farm naturally (
Fukuoka style). I want the erosion control of vetiver, and the wind break and natural aesthetic of bamboo.
I'm in central Illinois, zone 5b, so I need a good cold hardy bamboo, which it seems are mostly the running type and not clumping. So, I'm wondering if the vetiver would be an effective blockade to stop the bamboo from spreading off my land and into my neighbor's plowed field. I don't mind it running sideways or inwards a bit.
It seems vetiver is effective in stopping other invasive species, so I hope it can work against bamboo. Any thoughts on this combination?
