I had thought the heliconias would just get more densely packed as new shoots came up, but they haven't for me. I'm thinking about how to "fence" them in, underground, since I still hope that they'll ultimately re-sprout up through the degraded older sprouts, if they're forced to do so.

Anyone have any insight on this? Could I dig them their spot, say a full 12 inches down, line it with heavy (eg 60 mil) plastic sheeting (with drainage down) and expect that to block them?

some of mine...
