How are primroses overwintered?
If you have planted your primrose after the flowering period, you can protect the plant in winter as a precaution. From temperatures below -5 °C it becomes critical for the flower buds. Hibernation can be done outdoors or indoors in a cool place.
Proceed as follows for wintering outdoors:
- Cut off the flower stalks of the primula in summer
- Water the primrose one last time in the fall
- Remove dead leaves before overwintering
- At the end of September, cover with a layer of fallen leaves, brushwood, spruce branches
