got St. Pepin and Lacrosse. The suggested trellis system is a top cordon but you know those little shoots just love to grow up. So when I visited a local winery I noticed that their same grapes are growing off a bottom Cordon with catch wires above. That made since to me, so I'm trying it. Does anyone see a problem that I might run into with this system?? Also, when to Cordon's run into each other, should I just cut the ends off so they don't run over each other or wait until winter. thanks Gordon
