Answer: Wisteria can be propagated from root division, layering, from stem cuttings and from seed pods. Seeds should be started in late winter or early spring for transplanting outdoors when the weather is warm. Store your seeds over the winter by placing them in an airtight container and keeping them in a cool, dark place. When you're ready to germinate the seeds soak them for 24 hours in tepid water after nicking the seed coat to allow for water penetration. After soaking plant the seeds 1-inch deep in moistened seed starting mix, cover the pots or trays with plastic wrap to help hold in moisture, and keep at 55F-65F degrees. Seedlings will appear in 30-35 days. Plants started from seed may not bloom for 10 years! For this reason, you might want to try layering. It's easy and almost foolproof. Just find a long stem that you can bend down to lay on the ground. Dig a little trench a couple of inches deep and about 6 inches long. Lay part of the stem in the trench, cover it with soil and anchor it down with a rock or with unbent paperclips. Leave the tip of the stem out of the soil so it can grow upwards. Keep the soil moist (as you do with the original wisteria). Where the stem is buried it will develop roots. By the end of the summer it will have rooted and you can use a shovel to sever the rooted stem from the original plant. Plant the newly rooted wisteria in a new garden spot. Best wishes with your wisteria!
