In the fall, cut off pencil-thick stems 12 to 18 inches long that have at least three buds. Cut the end that was nearest the stem or trunk with a square, flat cut and make an angled cut on the other end so you can keep track of which end is which. Wrap the cuttings in damp cloth to prevent them from drying out.
Fill 1 gallon containers with potting soil and plant one cutting in each container. Plant cuttings with the square-cut end down, planting them deeply so that only one bud remains above the soil.
The containers should be placed in a sunny window or in a greenhouse and the soil kept damp but not soggy. Be patient -- roots and leaves will begin developing in three to six weeks.
Keep the containers indoors, keeping the soil damp but not soggy, until the final danger of frost has passed in the following spring. Choose a sunny, warm location on the south side of a building or on a south-facing slope, in a well-drained area. Dig a hole twice a large as the root ball on your cutting, filling half the hole with organic compost. Spread the roots out carefully and then cover, planting the vines the same depth as they were in your gallon containers. Plant vines 6 to 8 feet apart and provide them with a trellis or series of horizontal wires for them to climb and grown on. Keep the ground slightly moist but with no standing water.
