ah the rhizome barrier
please tell me more about this contraption
I have sheets of corrugated roofing
placed edgewise they might stop the rampant running

u could cut down whatever comes up in the wooded area .
Or you could use a rhizome barrier.

Something strong enough to stop the rhizomes and resistant to rot
decay corrossion and cracking buried 24-36" deep with 3-4" above the
surface and the wholle thing slightly angled out of the grove to
direct the rhizomes up and out where they can be severed.
The commercial stuff is 40-60 mil poly.

Poly what ? !
Polyethylene, Polypropylene, Polycarbonate, Polyvinyl Chloride ...

I guess that you mean Polypropylene, I'd be interested if you meant
polyethylene as I have some damp proof course that may suffice.
I suspect that Polycarbonate would work fine also - I have some that
is 0.75 mm thick and very tough.
