Propagating Wisteria

Do you know how to propagate wisteria vine? I have some vermiculite, but I'm not quite sure what to do.

Starting woody stemmed plants like wisteria, trees and shrubs from cuttings is a bit more difficult than houseplants and annuals. Proper timing and taking the right type of cutting are critical to success. Take 6 inch cuttings from new growth in June or July. Dip the cut end in a rooting hormone for woody plants. These products encourage root development and discourage rot. Stick the cuttings in moist vermiculite, perlite or well-drained potting mix. Keep in a warm humid shady location. Once rooted, plant the cutting in a well-drained potting mix and grow in a container. Once the plants are well rooted they can be moved to their permanent location. Northern gardeners need to bury the container for winter (if still in the pot) to provide needed insulation from the cold winter temperatures. Or start new plants by a propagation method called layering.
