Here is my attempt last year to try and restrict the spreading of the alstromeria. I got some plastic with holes that I hope is small enough to prevent the tubers from crossing through, and put it in about 8 inches deep. The barrier contained it enough so that I did not have to thin out in the fall - seems to be holding up OK. To the side and the rear of the alstromeria clump where there was no barrier, I still had to dig and toss.
