When to Take Trumpet Vine Cuttings

Optimal Timing for Trumpet Vine Propagation

Trumpet vine (Campsis radicans) is a deciduous woody vine. Propagation timing depends on the type of cutting:

Hardwood Cuttings (Dormant Season)

Take 6–8 inch cuttings from mature, leafless stems in late fall to winter (after leaf drop, before bud break). Store in moist peat or sand in a cool (35–40°F / 2–4°C) location until spring, then plant in rooting medium.

Softwood/Semi-hardwood Cuttings (Active Growth)

In late spring to early summer, take 4–6 inch cuttings from current season's growth that is firm but not woody. Remove lower leaves, dip in rooting hormone, and place in a well-draining mix under high humidity (e.g., under a plastic dome). Root in 4–8 weeks.

December Considerations

In December, the vine is dormant. You can take hardwood cuttings now, but they won't root until spring. Alternatively, wait until spring for softwood cuttings, which root faster and more reliably.

For best results, propagate in spring using semi-hardwood cuttings with bottom heat and mist.
