What do I need? There are several different types of vine training attaching products out there.  Here are some that I have tried.   Be sure to contact a distributor for a free sample of various types if they offer them.  Two Piece Snap Together Sleeve type - Blue X Milk cartons

 

Also, here's the progress with my new Vignole vines I planted back in mid April, 2003.   The one on the left is using the Blue-X growtube.   The one on the right is a snap together 2 piece growtube.    I have found the snap together growtube to be much easier later on for pruning lower growth as the vine gets older and starts reaching the trellis wire.

Here are the vines as of July 27, 2003.  From the photos to the right, you can make your own determination.   Personally, I like the snap together style of grow tube.  It is easy to remove for pruning.   Also, at the end of the summer months, you'll want to remove the grow tubes.   If you have the Blue-X style, you'll have to cut the replaceable plastic outer sleeve and order new ones the next year.
