Hibernate? Not necessary everywhere
Anyone who has planted the foxglove in the bed does not need to protect it with leaves and brushwood over the winter. This plant is hardy and can easily cope with temperatures down to -18 °C (-4F).
The hibernation procedure is only worthwhile if your thimble is in a pot, for example on the balcony. Cut down the foxglove in autumn and place the pot in a frost-free place. During this time:
- water sparingly
- do not fertilize
- do not expose to temperatures below 0 °C (32F)
If you don’t cut off the seed pods, the seeds will survive the winter unscathed. They mature and germinate in spring. Numerous new foxglove plants are often the result.
