Angel trumpets are among the non-native ornamental plants that are sensitive to frost and therefore have to overwinter indoors. In addition to proper handling in the winter quarters, wintering out is also important for a successful next season.
When should you put the angel trumpet outside?
The angel's trumpet should be put back outdoors after the last danger of frost in spring, ideally at the end of May after the Ice Saints. If the plant overwintered in cool, dark conditions, earlier overwintering is possible, but frost should be strictly avoided.
The wintering rules for the angel's trumpet
Proper wintering of cold-sensitive potted plants requires skill - after all, they are always plants that come from warmer regions than ours and for which the climatic conditions are generally not optimal here. So they definitely have a harder time than native species. This makes it all the more important to help them survive the winter.
- Due to its origin, angel trumpet is absolutely intolerant of frost
- correct wintering is therefore important
Wintering in and out at the right time
There is one thing that determines both the wintering in after the summer and the outwintering after the hibernation phase: Father Frost. He can put an end to the angel trumpet in just one night. You have to use it as a guide when it comes to the right time to bring it into the house and to put it out - of course every year is different. When the first frost occurs in autumn and when the last danger of frost is averted in spring varies.
So pay close attention to the weather forecast in autumn and save the angel's trumpet into the warm in time when the temperature is critical.
In spring the frost line can be treacherous. In some years, any danger of frost is already over in March - sometimes the month of April can be wonderfully sunny and warm, so that the angel's trumpet can easily stand outside. In May, however, the famous ice saints still threaten the last nights of frost. So be attentive again at this time and follow the weather forecast. If you want to be on the safe side, just don't put the angel trumpet outside until after the Ice Saints at the end of May.
Put out depending on the wintering quarters
What you should also consider when putting it out is the circumstances under which you overwintered the angel's trumpet. If it was kept bright and warm during the winter months, you should only put it out when the climate has become stable and mild. However, if you have overwintered them in a cool, dark place or in a greenhouse, you can put them out for the winter a little earlier - but there is also a strict ban on frost here.
