Trumpet vine (Campsis) can be propagated from cuttings. For a leafy cutting, use healthy semi-ripe growth: the current season’s shoot has begun to firm at its base while its upper growth is still flexible. Keep it in a suitable rooting medium with humidity, drainage and indirect light until roots develop.
The RHS Campsis guide also lists hardwood and root cuttings, as well as layering. Those are different methods with different material and timing. Do not combine winter hardwood instructions with the daily care of a leafy summer cutting.
Decide whether you want another vine
Campsis is vigorous and can spread by suckers. Identify the parent plant, check its suitability in your area and decide where the mature vine would grow before making more. A small cutting eventually needs appropriate support and room; pruning alone does not guarantee containment of underground spread.
Take material only with the owner’s permission. Use gloves if sap irritates your skin, clean cutting tools and a labeled pot. Prepare the container first so the shoot is not left drying while you find supplies.
1. Select semi-ripe growth
Look for a healthy, nonflowering shoot from the current season, usually in late summer into early autumn depending on local growth. Avoid visibly diseased material, damaged shoots and extremely soft tips. The right stage of growth matters more than a fixed calendar date copied from another climate.
Take a section long enough to prepare a cutting with several nodes. Work in a cool part of the day and protect the material from wilting. A node is the point where leaves or buds join the stem; it helps you identify the base and the portion to insert.
2. Prepare the cutting and pot
Trim the base just below a node, remove leaves from the lower portion and remove the very soft tip. Retain some healthy upper leaves. Do not bury leaves in the rooting medium. The RHS semi-ripe cutting instructions describe preparation and the need for a free-draining medium.
Use a clean container with drainage holes and a suitable propagation mix. Moisten it, make a planting hole and insert the lower stem so the cutting is supported. Firm gently and allow excess water to drain. If using a rooting product, follow its directions; more is not better, and repeatedly pulling up the cutting to reapply it is not useful.
3. Control drying without creating stagnant wetness
A propagator or clear cover can reduce moisture loss from the leaves. Keep the pot in bright indirect light, away from direct sun that can overheat a covered container. Inspect it regularly, ventilate as necessary and prevent leaves from remaining pressed against a wet cover.
Check the medium before watering. Keep it damp while the cutting roots, but do not leave the pot standing in water. Daily misting is not an automatic requirement if the enclosure is already humid. Remove dead or diseased cuttings rather than assuming a new pot or extra hormone will rescue rotting tissue.
4. Look for roots, not a deadline
Rooting time varies with the cutting, temperature and conditions. Do not promise success in four to six weeks. Fresh leaves alone do not prove a complete root system, and repeated tugging can disturb fragile roots. Look for root development at drainage holes or assess the root ball carefully when there is reason to believe it is established.
Once rooted, gradually increase ventilation before removing the cover. Pot on carefully into suitable growing mix when the roots can support the plant. Maintain the established planting depth rather than burying the stem deeply as a routine precaution.
5. Grow on before planting outside
Protect the young plant from conditions it has not adapted to, including frost and sudden strong sun. Harden it off gradually when local planting conditions are suitable. Water according to the new pot’s moisture rather than continuing the propagation routine indefinitely.
For final location, support and ongoing care, use our general trumpet-vine growing guide. Keep the propagation stage separate from mature-vine pruning and feeding: an unrooted cutting does not benefit from being treated as an established climber.
