If planning was carried out with foresight during the construction of a greenhouse, one already takes into account the Choose a location in the garden that provides the plants with sufficient shade if necessary donates. Somewhat older people can do that, for example tall trees or the gable wall of an already existing house is used, which at least partially shields the solar radiation during the midday heat.

The shade of tall plants as sun protection
If that alone is not enough, there is also the option of shading the greenhouse by cleverly planting it inside to mitigate excessive solar radiation. The plants are sorted according to size when they are placed in the greenhouse. Seen from the window front, the small varieties must therefore be placed towards the center of the house, i.e. in front of the large plants. So:
Shade giving palm trees and potted plants right next to the window and vegetables, orchids and alpine plants right in front of it.Climbing alternatives as greenhouse shading
Greenhouse shades made from annual climbing plants are visually very impressive, but not entirely without their disadvantages. They grow extremely rapidly on the greenhouse walls from the outside towards the roof and, with their dense foliage, ensure a sufficient amount of shade inside. At the same time, the internal temperatures rise much more slowly with long-lasting summer heat than without the vegetation. Well suited for this natural external shading of greenhouses are wax flowers as well Whistle winch or, as the most famous representative, the grapevine. Unwanted side effect of this shading: It is constantly effective, even if it is actually because of it lack of solar radiation is not required and also causes a very high level of radiation Maintenance effort.
The light requirements of the plants are very different
When choosing a shading that is really sensible and adapted to nature, it must be assumed that the light requirements, especially with ornamental plants, can be very different. In addition, there are long and short day plants (Christmas star, Chrysanthemums), where day and night lengths are essential for flower formation and growth. Depending on the crops planted, it can therefore make sense for the greenhouse to provide shade differentiated on the respective segments of the greenhouse and not as a whole.
Tips
The fruit plants as well as most of the common vegetables in this country are plants that need a lot of light. Therefore, they only need to be shaded in such cases when the internal temperature in the house rises too much.
