Construct a greenhouse to overwinter

A greenhouse either belongs to the group that is designed for wintering or to a non-frost-resistant plant shelter. Some types of construction are excluded for winter operation. The heat requirement of the plants is important. For exotic species, additional heating is required, while many native species only need to be protected.

Overwintering can be temporarily or permanently resolved

There are several ways to organize wintering in a greenhouse:

  • The building will be made permanently winter-proof
  • The building is seasonally and temporarily made winterproof (bubble wrap)
  • An inflatable greenhouse is placed over the plants and heated

So-called cold greenhouses do not need heating for temperatures between four and ten degrees Celsius. For warm greenhouses, also known as greenhouses, temperatures between 15 and 25 degrees are required. In order to keep them at this temperature level even when there is severe frost outside, permanent and effective insulation must be in place.

Prevent frost traps

If a greenhouse is to withstand the frosty climate, cold spots and ground frost must be considered.

  • Cold bridges occur wherever highly conductive materials come into contact. In the case of metal, the support structure should be provided with interrupting components such as rubber blocks or silicone injections.
  • Ground frost "moves" through the earth. A circumferential strip foundation at least eighty centimeters deep protects the soil in the greenhouse. If there is no demarcation, wooden boards sunk into the ground can form a frost barrier.
  • In order to reduce the risk of freezing, a construction above the subsurface is recommended. The air buffer under planks and boards has an insulating effect.
