Jasmine is a climbing shrub that can quickly overgrow a wire fence, or any other surface. The plant needs no assistance in getting established on the fence structure, but it is necessary to regularly prune and train the vines to travel in the direction you desire. The jasmine vine is evergreen, meaning it will continue to produce foliage throughout the year. In early summer, it blossoms with fragrant white flowers.
Prune the jasmine vine, using garden shears to remove any dead or damaged vines. Cut them back to the ground. Prune the jasmine in early fall, before the cold sets in.
Select the strongest vertically growing vines and cut them back to 1/3 of their length with the garden shears. Cut back the weaker vertical vines to the ground. This encourages the vine to strengthen the already successful shoots, and prevents the plant from only producing foliage at the tips.
Unravel any vines that are travelling in a direction you do not want and carefully wind them around the wires in the fence that lead to the direction you want the plant to grow. Secure the vine to the fence with a twist tie. Check the tie once a week to make sure it isn't cutting into the plant, and remove it once the vine establishes itself in the correct direction.
If you are starting with a young plant, unravel all vertical shoots and wind them around the lowest horizontal wires in the fence. Once the plant has vines along the entire length of the fence, allow it to begin growing upwards.
Jasmine might need pruning several times a year to keep it growing in the manner you desire.
