How to Propagate Trumpet Vine from Cuttings

by

Propagating trumpet vine (Campsis radicans) from cuttings is a rewarding way to expand your garden with this vibrant, flowering plant. With proper technique, you can easily grow new trumpet vines from cuttings taken in the right season.

Choosing the Right Time

The best time to take cuttings is late spring to early summer when the plant is actively growing. This ensures the cuttings have enough energy to develop roots and establish themselves.

Preparing the Cuttings

Follow these steps to prepare healthy cuttings:

  • Select a healthy, mature stem that has at least two to three leaf nodes.
  • Use clean, sharp pruning shears to make a 4-6 inch cut just below a leaf node.
  • Remove the lower leaves to expose the node and reduce moisture loss.
  • If desired, dip the cut end in rooting hormone to promote faster root development.

Rooting the Cuttings

Follow these steps to root your cuttings successfully:

  • Fill a pot with well-draining potting mix or a mixture of peat and perlite.
  • Make a hole in the soil with a pencil or stick.
  • Insert the cutting into the hole, ensuring at least one node is buried.
  • Gently firm the soil around the cutting.
  • Water lightly to settle the soil and maintain moisture.

Caring for the Cuttings

Proper care encourages rooting:

  • Place the pot in a warm, bright location with indirect sunlight.
  • Maintain consistent moisture in the soil, but do not overwater.
  • Cover the pot with a plastic bag or a clear plastic dome to create a humid environment.
  • Ventilate occasionally to prevent mold and fungal issues.

Monitoring and Transplanting

Root development typically takes 4-8 weeks. You can check for roots by gently tugging the cutting—resistance indicates successful rooting.

Once roots are established, gradually acclimate the new plant to outdoor conditions by removing the plastic cover and increasing sunlight exposure. Transplant into a larger garden bed when the plant is strong enough.

Tips for Success

  • Use sharp, clean tools to prevent disease.
  • Take cuttings on a dry day to reduce disease risk.
  • Ensure good soil drainage to prevent root rot.
  • Be patient; some cuttings may take longer to root.

With these steps, you can successfully propagate trumpet vine from cuttings and enjoy its beautiful, trumpet-shaped flowers year after year.
