Propagation via seeds is (mostly) easy
The large flowers develop up to 40 centimeters long by autumn, bean-like podswhich is why the trumpet tree is also nicknamed "bean tree". These remain on the tree until the following spring and do not ripen until then. You can harvest the very fine seeds inside when the pods have turned brown. Sow the seeds in Potting soil, cover it very lightly and place the seed container in a light and warm place. Usually the small grains germinate within a few days.

Propagate the trumpet tree using cuttings
However, not all trumpet trees produce seeds. In this case, fruits hang on the tree, but they are empty. By the way, you have the best chances of getting seeds after a very warm and rather humid summer! Alternatively, the trumpet tree can also be used Propagate via cuttings. Cut these after flowering in late summer, this year's shoots being best.
- The cuttings should be about four to six inches long.
- Cut the shoots so that there is a sleeping one just above the cut eye is located.
- Remove all but the top two leaves.
- Cut the leftover leaves in half.
- Dip the slightly beveled end into a rooting substrate.
- Plant the cutting in a pot with potting soil.
- Put the pot in a warm and bright place.
- Keep the substrate evenly moist (but not wet!).
Hibernate the cutting frost-free, but cool and cultivate it in the bucket for the first two years if possible.
Tips
Older trumpet trees very often form sinks of their own accord, which take root in the direct vicinity of the mother plant. You should always remove these, but you can also cut them off and use them like cuttings for propagation.
