Angel trumpets are not native to us and cannot tolerate frost. They are therefore candidates for separate overwintering. In the following article, we will explain how you can ensure the right conditions for the Andean plant in its winter quarters.
How can you properly overwinter an angel's trumpet?
In order to successfully overwinter an angel's trumpet, a bright winter quarters with temperatures of 12-18°C or a dark, cool room with minimal watering is recommended. From March/April the plant should be repotted and gradually accustomed to sunlight.
The frost sensitivity of the angel trumpet
The angel's trumpet originally comes from the South American, subtropical Andes, where frost is a foreign word. And even though they occur at altitudes of up to 3,000 meters in the Andes Mountains, their temperature tolerance does not extend far below. In short: Before the first announcement of frost, you must move the angel's trumpet, if you have displayed it outside over the summer, to winter quarters.
- Angel trumpet comes from subtropical areas
- Temperature tolerance therefore not below 0°C
- Get in before the first frost
Adapt wintering conditions to location
You can choose different places for the angel's trumpet to overwinter. Unlike some other plants that require overwintering, it does not need to be particularly bright or particularly dark. However, depending on the lighting conditions, you should ensure adequate accompanying conditions, especially in terms of temperature.
Bright location
If you have a winter garden, you can overwinter the angel's trumpet there. It requires a temperature of around 12 to a comfortable 18°C with constant winter light. In warmer conditions it can even produce a flower. You should water regularly in a bright, heated room, but of course to a limited extent.
Dark location
You can also “shut down” the angel trumpet completely for the winter and put it in a dark place. In that case, bring them to maximum vegetation restriction. Accordingly, you should leave them alone and only water them enough so that their root ball doesn't dry out.
Wintering
After overwintering, you can bring out the angel's trumpet again from March/April. Repotting with the addition of long-term fertilizer is recommended as a spring treatment and jump-start. You should also gently accustom the plant to sunlight, especially if the winter quarters were dark.
