Tips
The increase
the trumpet flower also works very well at home. It is better to keep these delicate plants indoors in the first winter and only plant them in their permanent location in spring.Container plants threatened by frost
All winter-hardy trumpet flowers that grow in the tub are more exposed to frost than planted specimens. Your pot is covered in icy cold on all sides, so that the earth can freeze through faster. Therefore, these trumpet flowers should only be exposed to light frost. You can do this by hibernating the plant in a garage, for example.
If the bucket has to be outside, take suitable protective measures:
- Place the pot protected from wind and rain
- Lay the styrofoam underneath
- Cover the pot with fleece or raffia mats
- Cover the root area with leaves or fir branches
