Young trumpet tree does not tolerate frost
Many people confuse the up to 18 meters high awake trumpet tree (Catalpa bignonioides) with the sometimes also called angel trumpet (Brugmansia). While the latter is absolutely not hardy for us, the handsome trumpet tree gets used to frosty temperatures within three to four years. The deciduous deciduous tree survives the Central European winter the better, the older it is and the more protected it stands.
In his home country, it is rarely really cold
Originally, Catalpa originates from the southeastern United States, where the climatic conditions are rather mild and average annual mean annual temperature is around 20 ° C. Correct frost is very rare here, even though the degrees can fluctuate around the zero point during the winter months. Although the temperature differences are not quite as pronounced as here, they are nevertheless present. No wonder then that the trumpet tree needs a winter break - as well as a long and very warm summer, because only then he trains seeds.
Older trees are less sensitive
While younger trees are very susceptible to frost up to the age of about four to five years and therefore, if they are planted out in the garden, need a good winter protection, older specimens are considered much more robust. Nevertheless, it is also advisable to protect the crowns of these trumpet trees from frost by means of a foil or the like: Catalpa develops its flower buds already in the autumn of the previous year, so that they may freeze to death due to severe frosts or especially as a result of late frosts. In contrast to the great relatives ball-trumpet trees remain life-long sensitive to frost, a good protection is therefore inevitable - even if it is rare to warm flower buds here.
The trumpet tree in the bucket overwinters best frost-free
If you cultivate - possibly still a young - trumpet tree in the tub, it is recommended for this a cool, but frost-free wintering. Since the tree throws off its leaves in autumn, the winter quarters do not necessarily have to be bright. Due to the small amount of substrate in the planter, the roots threaten to freeze due to overly cold temperatures.
Tips
If the trumpet tree feels comfortable at its location, it can withstand the cold season significantly better. So, if possible, choose a sheltered, sunny spot where the tree is not exposed to drafts and where it stays slightly warmer year-on-year. Ideal is a south-facing location near a house wall.
