A tree girdling technique that uses a water jet cutting device to effect girdling of a tree (10). After making an undercut (12) in a tree, a girdler is wrapped about a tree at an elevation lower than the undercut and pressurized water with abrasive particles are dispensed from the girdler about the girth of the tree. The dispensing may be done either by rotating a port about the girth or by positioning a series of ports (60) each arranged to direct the pressurized water with abrasive particles to flow in a stream at an oblique angle relative to the inner face of the girdler. |
