Overwintering citrus plants – what you need to know

by Johannes

If you want to overwinter citrus plants, the most important factors are the right ambient temperature and the light conditions of the location

Hibernating citrus plants in the right location

Citrus plants, such as lemon trees, are sensitive and have certain requirements when it comes to where they are overwintered.

  • As soon as the outside temperatures approach zero, it is time to move your citrus plants indoors.
  • The following applies to the location: the darker, the colder and the lighter, the warmer.
  • If you have a conservatory, keep the temperature there between 10 and 15 degrees Celsius.
  • If you have a garage, garden shed or cellar, citrus plants can also be overwintered there.
  • It is important that there is a window so that some light can enter. The ambient temperature should be between 5 and 10 degrees Celsius.
  • However, the roots must not become too cold. Therefore, place the plants on an insulating base, such as polystyrene sheets.

Caring for citrus plants during the winter

During the winter, citrus plants do not require much care.

  • Test every two weeks whether the top third of the soil has dried out. Then water moderately with lukewarm water.
  • Ventilate the room regularly to prevent mold from forming on the plants.
  • In addition, check the citrus plants regularly for scale insects. This can occur particularly in warmer locations with dry heating air.
