Wintering of plants in the cold winter garden

One of the main uses of a cold winter garden is to be able to overwinter plants protected against frost. Which types of plants in the winter garden can overwinter and what must be laid in the design of the cold winter garden, you can read here.

Conservatory as winter quarters

The cold winter garden is the ideal winter quarters for plants that do not tolerate frost. However, care must be taken that the conservatory is also designed accordingly.

Bright and airy design

Conservatories are usually located on the south side of the building and get enough sun. For potted plants that you want to overwinter in the winter garden, a sufficiently bright location is essential.

Even more important, however, is the good ventilation. Therefore, the wintering in musty cellars is often problematic. The winter garden has the same prerequisites: it must have the best possible ventilation.

You should definitely remember that the light behind the window of a winter garden is less intense and less usable for the plant than in freedom.

temperature range

For wintering of plants, temperatures between 5° C and 10° C are optimal. This bans the risk of frost. However, the temperature should not be warmer than 10° C during the wintering period.

If necessary, appropriate measures must be taken to prevent the temperature from rising - possibly due to shading. Of course, frost in the conservatory should also be avoided. It is best to have regular temperature control to know when to act.

At too high temperatures, the plant metabolism is boosted. If the plants then not enough solar radiation available, they can "hurry". They then form only very long and weakly thin shoots with very small leaves.

The sunshine inside the conservatory is less intense, so the temperature should be lower than 10° C, so that a Verwgeilen is avoided. This is especially important for evergreen, exotic species:

  • oleander
  • laurel
  • Date palm
  • Citrus species (not all are equally sensitive)

pest control

Even during the resting phase of the plants during wintering a regular sparing watering and basic pest control is necessary.

The plants should be checked regularly for pest infestation. This is especially important on the underside of the leaves and on the branches.

If dead plant parts are removed and fallen leaves are discarded at regular intervals, this can help to prevent fungal diseases. Especially in the winter garden densely planted pests and fungi can often spread even better, so you should take care here carefully.

Alternative: Hibernate at the nursery

If you do not have a winter garden, you can usually give your plants to a nearby nursery for wintering. The costs are generally around 50 - 70 EUR per square meter of floor space for the entire winter season. However, occasionally there may be additional costs for transport and special services.
