Answer: Clematis vines climb by twisting their petioles (stems of leaves) around any available support. I've found that a wooden trellis is unsuitable because the wooden slats are too wide. A wire trellis would be appropriate because the wires are thin and would also be strong enough to support the weight of the vine as it got bigger. Chicken wire would not be strong enough but a heavier grade wire might do the trick. Since Clematis are woody perennials the stems would provide winter interest and would probably hide whatever trellis you decide on! Good Luck!
