How to String Grape Vines

Grapes are enjoyable vines to grow in your yard. They grow quickly, and even in the first couple of years before they produce much fruit, their leafy green branches add a handsome touch to your grape trellis. One of the steps in supporting grapes is the process of stringing them to the trellis. It is a simple process after you have done it once. There are just a couple of factors involved.

Cut a section of string that is long enough to go from the bottom of your grape vine to the top wire of your trellis--typically about 6 feet. Add a few inches to your length to allow for making a knot .

Tie a simple knot at the base of the grape vine. Since you only do this process when the vine is 1 or 2 years old, the trunk will be only 3/4 to 1 inch thick. Make the knot loose enough to slide a little or it might constrict the bark during the year as the vine grows.

Pull the string up so there is barely any tension on the plant. Tie the other end of the string off to the top wire of your trellis. Make a strong knot that will hold for the whole year. This will train the plant to grow straight up to the trellis.

Twist your grape vine's main growing branch counter-clockwise around the string a few times. As the vine grows during the summer it will continue twisting and growing straight up. Pinch off any shoots that might grow on the sides of this vine.

Cut the string off when the vine reaches the top of the trellis and you train it to grow sideways along the trellis. This is now the trunk or main stem of your grape vine.
