How to Propagate Snail Vine

Snail vines are climbers capable of growing up to 25 feet long. In summer, lavender and off-white blooms shaped like snail shells adorned the snail vine. The vines thrive in U.S. Department of Agriculture Zone 9 and above, but grow for a single season in areas farther north. Propagate the vines from seed sown directly into the garden or from softwood cuttings taken during spring or early summer. Propagation success depends heavily upon the chosen planting site. A location with full sun exposure and soil holding moisture without remaining wet is ideal.

Instructions

  1. Propagation from Seed

    • 1

      Drop snail vine seeds into a container of water and soak them overnight.

    • 2

      Clear the growing site of vegetation and loosen the soil 4 to 6 inches deep.

    • 3

      Plant the snail vine seeds at a depth equal to half their diameter. Water until the soil feels damp.

    • 4

      Add additional water only when the top 1/2 inch of soil feels dry. Watering more causes the seedlings to rot.

    Propagation from Cuttings

    • 5

      Cut a 4- to 5-inch piece of the vine. Use sharp pruning shears and make a smooth cut.

    • 6

      Fill a 3 inch growing container with perlite and add enough water to moisten it evenly.

    • 7

      Pull the leaves from the lowest half of the cutting.

    • 8

      Dip the clipped end of the cutting in rooting compound.

    • 9

      Poke a hole in the perlite with a pencil so that the rooting compound isn't accidentally rubbed off the cutting. Insert the bottom 2 inches of the cutting into the perlite.

    • 10

      Slip the container into a clear plastic bag and seal it.

    • 11

      Move the container to a brightly lit area away but from direct sunlight.

    • 12

      Pull gently on the cutting every week until you feel resistance, which means roots are growing. Remove the container from the bag when this occurs.

    • 13

      Transplant the new snail vine to its permanent location before cold weather arrives.
