Sometimes called "trumpet creeper," the trumpet vine (Campsis radicans) has aerial roots that stick to walls, allowing the stems to climb 30 feet unless you prune them. The deciduous plant is hardy in U.S. Department of Agriculture zones 4 to 9, where it blooms in the summer, bearing the orange trumpet-shaped flowers that give the vine its common name. The blossoms attract hummingbirds thirsty for nectar to the garden. Root cuttings are a method of starting new trumpet vines to grow them elsewhere. Cut the root while the vine is still dormant in later winter to early spring.
Items you will need
- Sand or sawdust
- Saw, as needed
- Machete, as needed
Fill a container that can accommodate a 6-inch-long root horizontally with sand or sawdust. Moisten the medium.
Dig carefully near the plant's base to expose one section of the root system. Continue to get the soil out, following the spread of one root 6 inches away from the base.
Cut the root at a point close to the base. Use the blade of a sharp spade, a saw or machete to sever the root from the tree.
Chop the same root 6 inches away from the trumpet vine at a slant.
Take the root cutting gently out of the ground. Bury it in the moist sand or sawdust you prepared. Keep it at 40 degrees F for the next three weeks.
Loosen the ground where you plan to grow the new trumpet vine. Remove debris and vegetation from the area. Rake the bed to smooth it out.
Make a narrow hole 3 inches deeper than the cutting is long--about 9 inches deep. Plant the root piece, slanted end in first. Verify the cutting is 3 inches below the soil surface and cover the hole. Keep the soil moist to help the root develop and send a new shoot through the surface.
