Anyone who suspects that the trumpet flower is difficult to propagate at home is very wrong. A new plant can develop from almost any part of a plant, from the root to the seed. Sometimes the plant does it alone, sometimes you have to take action.

The five methods at a glance
- seed sowing
- cuttings
- root cuttings
- foothills
- lowering
seed sowing
Let the seed pods mature on the trumpet flower and then let nature take its course. If you later discover a young plant close to the mother plant, you can dig it up and transplant it. Self-sowing is so successful that most owners try to prevent it by removing faded flowers.
If the dry seed pods burst, you can collect the seeds and sow them indoors.
- Sowing is possible all year round
- Pre-soak seeds for six hours
- then place on a damp substrate
- do not cover with soil
- Always keep the substrate moist
- the germination time is about 4 weeks
cuttings
- In July or August, take semi-mature cuttings 20 cm long.
- Fill small pots with potting soil.
- Insert the cuttings and water them.
- Put a transparent plastic bag over each (air regularly)
- Put the pots in a warm and bright place.
- As soon as a cutting has formed sufficient roots, it will visibly sprout new leaves. It can now be transplanted.
tips
A young trumpet flower is not yet sufficiently hardy. When wintering outdoors, you should cover the root area with a thick layer of leaves and wrap the above-ground parts of the plant with jute or protect them with fir branches.
root cuttings
This method is more complex than the others. These are the individual steps:
- expose part of the root area in autumn
- Cut off finger-thick parts of the root
- mark the lower end (so that the planting is done correctly)
- store frost-free in moist coconut fiber
- only cut into 5-10 cm long pieces and plant in winter
- use a coconut fiber and sand mixture
- Cover root pieces 2 cm with substrate
- brighten as soon as budding appears
tips
The sap of the trumpet flower is poisonous and can cause allergic skin reactions. Therefore, wear protective gloves when cutting.
foothills
If runners have formed, separate them from the mother plant and dig them up. They are planted immediately after their future location.
lowering
A previous year's shoot of the climbing plant is bent down to the ground and covered with soil, with the tip still sticking out. If necessary, the shoot is fixed with wire or stones. After that, the soil is kept constantly moist. If the sinker sprouts again, this is a confirmation of successful rooting. The new plant is separated from the mother plant and transplanted.
