Does anyone have any other rhizome barrier ideas (besides the regular
rhizome barrier, and large drum.)? I want my bamboo to grow big in my
pasture, with plenty of room to roam. So, I need a new idea or cheaper
material for a rhizome barrier. I have a 1 acre lot I am going to turn
into a multiple variety bamboo grove. Needless to say, I am going to
need about 2500 ft of rhizome barrier at the least. 2500 feet of
rhizome barrier at $2 per foot is a whole lot more than I want to pay.
Any suggestions?

You could mow a 15m wide path around the perimeter once a month. Young
bamboo shoots are much thicker than grass, but an ordinary mower will still
take care of them.
