Many palm lines survive high minus temperatures without problems. However, what bothers them is too much moisture in the cold season. But you can counteract this purposefully.The family of palm trees or yuccas (Yucca) includes hardy and non-hardy species that have different demands on the winter habitat. So before you make any arrangements, you should know exactly what type of palm tree it is.
Then you can take appropriate measures to enjoy the exotic flowers again next year. Here I would like to explain exactly how the different species need to be protected in winter time.
➜ Hibernate frost-hardy palm trees outdoors
Frozen palm trees are used to the clamor of nocturnal cold in their natural habitat of North America. These species include many yuccas, which are very popular as ornamental plants, for example:
- Filamentous palm-leaf (Yucca filamentosa)
- Candle palm-tree (Yucca gloriosa)
- Blue Palme Lily (Yucca baccata)
- Trans Pecos Yucca (Yucca thompsoniana)
- Big Bend Yucca (Yucca rostrata)
Adult specimens of these species can cope with temperatures of -20° C and sometimes even -30° C and survive the mostly milder winters in Germany well. However, in the cold season, the plants are at risk of too much water in the form of rainstorms and melting ice and snow. Persistent waterlogging is extremely harmful to many palms from arid or semi-arid areas. You can already take the following protective measures when planting:
- mix plenty of sand or gravel into the soil at the site and drainage
- Planting palm trees raises to further enhance water drainage
- Plant palm trees under roof (carport, canopy) while leaving the plant as much sunlight as possible
Build rain cover for palm trees yourself
If you do not shy away from a little effort, you can build a simple but effective rain cover for the Palmlilien itself without special knowledge. That's how it's done:
- Anchor four posts firmly in the garden soil.
- Allow two adjacent posts to protrude higher, creating a slope of at least 30 degrees.
- Screw or nail a frame of slats with two diagonal struts.
- Put on a stable, transparent film and fix it with a stapler.
- Leave at least one, better two sides open for the aeration.
➜ Do not overwinter frost-hardy palm trees indoors
No or only partially frost-hardy Yuccas should be cultivated in the tub and kept in a cool place in the house over the winter. This applies, for example, to:
- Giant palm-tree (Yucca elephantipes)
- Mojave Yucca (Yucca Schidigera)
- Gray palm-tree (Yucca aloifolia)
Choose a cool, bright place in the house, where temperatures between 5° C and 10° C prevail. Pour very sparingly, and less so, the colder the winter quarters. When fingering you should feel only a little moisture on the root ball. A regular, weak misting of the leaves with the spray plant gets the palms, however, good. Additional advantage: they counteract the infestation of spider mites with the mist shower.
