      Use machete to chop up the growing tip (apical meristem). Works good. Just need to make sure that new workers chop up enough of the growing tip to kill the plant. We give a quick anatomy lesson to new workers so they understand what not to do: 1) not chop it up enough or 2) cut down a tree fern trunk without killing the growing tip.
