Angel Trumpet: Tips For Cultivation And Care

Angel trumpets are popular container plants. Nevertheless, if possible, you should put them directly into the ground. This way the plant can spread better and gets more nutrients. Over the winter, however, you will have to put them back in a frost-free place.

  • Location: sunny and protected from wind
  • Time: plant out from April (frost-free)
  • Soil: humus-rich, nutrient-rich, loose


As soon as there is no more frost in spring, you can plant out the Angel’s Trumpet. Potted plant soil is ideal for the plant. It contains ten percent expanded clay, which stores water and continuously releases it to the plant. Of course, you can also mix your own soil with expanded clay. If you use a flower pot, you should place a layer of expanded clay at the bottom.

Caution: cut angel trumpet

You should only prune the angel’s trumpet when it has grown too large. Any pruning will reduce the flowering next summer. There are a few things to keep in mind:

Cut back the angel’s trumpet in the fall – a few days before wintering.


The plant has symmetrical and asymmetrical leaves. Flowers will only form later on shoots with asymmetrical leaves. You can recognize these leaves by the fact that a part is missing from the lower end of one half of the leaf.
At least one asymmetrical leaf must remain on each shoot for new flowers to appear in the spring.

Overwintering angel’s trumpet: how to do it successfully


Angel’s trumpets are sensitive to frost. Therefore, you must bring them indoors in the fall, but then water them only rarely:

  • The perfect conditions are provided by a greenhouse that lets in plenty of light and has temperatures of five to ten degrees.
  • A conservatory is also suitable, where it is between ten and 15 degrees warm.
  • Alternatively, you can overwinter the plant in the dark (max. five to ten degrees). It will then lose all its leaves, but new ones will sprout in the spring.
  • If you have planted the plant in the bed over the summer, you can put it in a large flower pot over the winter. Dig it up carefully with a spade. Many roots will be lost in the process, but the plant will not mind.

Propagate angel’s trumpet


The easiest way to propagate angel’s trumpet is by cuttings:

Cut a branch below the base of a leaf.
Remove the lower leaves and put the branch in potting soil.
After about three weeks, roots will form. Then you can plant out the plant in a flower pot.
Alternatively, you can harvest angel’s trumpet seeds in the fall and sow them in the spring. Even then, it takes about three weeks before you can plant the plants in flower pots.
