Your goal is to fill your trellis with permanent cordons. There probably isn't enough time this year to do this. You have two choices- begin training now thru dormancy and continue in 2014 OR cut down to two buds at dormancy and start 2014 with a new trunk and start training anew.

Thank you so much for your response to my question flatwoods. I am in southeast Texas and we have a long growing season, usually with our first frost in late November/early December, so I think I will start the training now. I understand that I would prune to two buds to start the training, right?

You mean two buds at ground level? Wait until Xmas to cut it. You need all the energy this year's leaves provide.

Thanks again for your advice. I will hold up on the initial pruning.
