| Generally, to take a portion of a plant, you just drive a spade straight down into it and get as much of the rootball as you can with the part you're taking away.
I'm no expert on the agave particularly, but from the looks of how it "funnels down" to the rootball, I fear that that you'd kill the plant by trying to break it up.
I hope someone in the know about agave will pipe in. |
