How to Cut & Root Wisteria
- 1). Fill a 1-gallon terracotta flower pot one-third full of sand. This will help the wisteria cutting drain properly.
- 2). Fill the pot up to about a half-inch below the rim with a perlite and vermiculite potting mix. This mix is light and airy but holds moisture very well. Pour the mixture slowly; it will try to puff up out of the pot at the slightest breeze.
- 3). Take cuttings from wisteria plants in late summer. The flowers should be in full bloom but not yet wilted or gone to seed.
- 4). Snip a wisteria twig about 6 inches long, taking a little of the main stem (a rounded "heel") with it. Dip the cut end of the cutting in some liquid rooting hormone. The hormone encourages root growth and prevents mold or root rot.
- 5). Push your finger 1 inch down into the perlite-vermiculite mix and slip the cut end of the wisteria into the mix. Press the mix around the wisteria's stem with your fingers.
- 6). Water the potting mix until water stops draining from the bottom. This means the mix is fully saturated and the wisteria has plenty of water. Set the pot on a flood tray in a sunny window.
