Propagating Trumpet Vine (Campsis radicans): Cuttings, Suckers, and Seeds

Best Methods

1. Suckers (easiest): Dig up rooted shoots from base of mother plant in spring.
2. Seeds: Collect pods in fall; sow fresh or stratify.
3. Stem cuttings (slow): 4" semi-ripe wood in summer; dip in hormone; root in sand/perlite; may not show roots until next spring.
4. Root cuttings: 2" pieces in December; cold frame; shoots in spring.

Cutting Protocol

• Take cuttings in morning.
• Remove lower leaves.
• Keep humid (plastic bag/dome) and warm (70°F).
• Transplant when roots are 1–2" long.

Suckers give the fastest, most reliable results for this vigorous vine.
