The poisonous Japanese heather lavender does not have much in common with real lavender, although its name suggests otherwise. Those who cherish and care for them will enjoy them for a long time. But only if it survives the winter season…
The Japanese lavender heather tolerates temperatures down to -23°C
The Central European winter is survived
You can rest easy: the Japanese lavender heath is ready for the Central European winter. It tolerates frost down to -23 °C. However, it can sometimes happen that it does not survive the winter. What can be the reason?
In the bucket: Frost protection is required here
A Japanese heather lavender that was in a pot or bucket on the balcony or terrace can freeze to death in winter. For this reason, all Japanese lavender heathers in pots/tubs should be provided with frost protection in late autumn.
That's how it's done:
- shorten too long and thin shoots
- Discontinue fertilizer application from August
- water abundantly until late autumn
- from the end of October, cover the pot with fleece, bubble wrap or jute
- put the wrapped pot on a block of wood against the wall of the house
Beware of the winter sun
Not only shadow bells in pots are endangered during the cold season. Even bell peppers that stand in the blazing sun in winter (the sun is lower in winter) can suffer if deep frost prevails at the same time as the sunshine. The flower buds and young shoots can be destroyed by the interaction of frost and sun.
To prevent this, you should plant your Japanese lavender heather in a semi-shady to shady location as a precaution. If it is exposed to the winter sun there, it should be covered with leaves or brushwood. From February, the protective cover can be removed again so that budding is not hindered.
Don't let the soil dry out
Keeping the soil of this evergreen plant dry is also crucial to surviving the winter. It is not uncommon for people to think that they don't have to care for their plants in winter. But when there is a drought, this evergreen plant needs water.
tips and tricks
In cooler and not wind-protected locations, the Japanese lavender heather should always be protected in winter. The cool and dry winds could damage their leaves, among other things.
