Make it winterproof - absolutely necessary?

Most types that are commercially available in this country are hardy and tolerate frost. However, if you want to sit at home with a clear conscience in winter, you should provide your primroses with appropriate protection as a precaution. This is especially true for potted primroses.

Prepare potted primroses for the winter from the end of September

It is not necessary to prune primroses before winter sets in. You don't need a pruning. Watering should not be stopped, but rather shut down. Fertilizers should not be applied after the end of the flowering period. From the end of September, the primroses in the pot should be prepared for the winter.

How are potted primroses winterized?

If the pot is on the balcony, it should be taken out of the window box and placed against the wall of the house. There, primroses are protected from the weather. At the same time, a portion of warmth from the house flows towards them through the wall.

As soon as temperatures approach 0 °C in winter, it is advisable to wrap the pot in newspaper or fleece. Likewise, it is good to protect the primrose flowers by covering them with an insulating material.

At temperatures below -2 °C it is better to put them indoors

If the thermometer reading continues to fall, potted primroses should be placed indoors. Otherwise, there is a risk that the flower buds will freeze, the pot will freeze through, and the end of the primroses will be near. The location in the house should have the following characteristics:

  • shady
  • cool (5 to 12 °C)
  • well ventilated
