Most gardeners know that lobelia are sensitive when it comes to low temperatures. But some lobelia, such as those found in wine-growing areas or perennial lobelia, can be overwintered.
The roots of lobelia outdoors should be protected from frost for wintering with leaves and branches
It's best to change location
To be on the safe side, perennial lobelia should be quartered. That means: a change of location to a cool place of 5 to 10 °C. The lobelia remain there until mid-May and are then slowly accustomed to direct sunlight again.
Get outside through the winter
In mild climates, some lobelia can be overwintered outside:
- cut back in autumn
- Reduce pouring from August
- Water gently in winter when dry
- cover with leaves, brushwood or spruce/fir branches
tips
If you want to overwinter your lobelia, but a frosty night has already passed, there is no need to panic. These hardy plants survive brief frosts.
