Crossvines provide a beautiful display of orange trumpet-shaped flowers formed in clusters during the summer months. Although the crossvine becomes invasive if left unattended, the plant makes an excellent choice for trellis growing. You can start crossvines from cuttings taken during June or July to add this beautiful vine to your garden.
Choose healthy vines from which to take cuttings. Select crossvine stems about the same thickness as a pencil. Cut 6-inch sections of the crossvine with at least one leaf node at the bottom of the cutting. Place the cuttings in water until you are ready to plant.
Moisten the potting soil with warm water so the soil has the feel of a damp sponge. Squeeze out any excess water with your hands. Fill the growing pot with the potting soil. Make several uniform holes in the soil for planting the crossvines.
Remove the bottom leaves of the crossvine cuttings by running your hand gently along the vine. Leave the top two or three leaves on the cuttings. Trim the remaining leaves if they are large to keep the crossvine cuttings from touching each other in the growing pot.
Dip the cuttings into the rooting hormone and shake off any excess. Stick the crossvine cuttings into the holes of the soil in the growing pot. Place three or four cuttings in each growing pot. Tamp down the soil.
Slide the entire growing pot into the clear plastic bag, or cover the pot with plastic wrap, to form a mini-greenhouse around the crossvine cuttings. Secure the top with a rubber band or twist-tie. Place the growing pot in a warm, bright location but avoid direct sunlight.
Check the crossvine cuttings daily to remove any dead or dying cuttings and to keep the soil moist. Mist the soil when it is dry with a spray bottle of water. Do not over water the soil to avoid root rot.
Test the crossvine cuttings for root growth after six to eight weeks. Gently tug the cuttings to feel for resistance. When roots have formed, pot up the new crossvines in separate containers, and over the winter, keep them indoors until all danger of frost has passed. Transplant into a permanent location in the spring.
