The best results are achieved, if the eggplant is cultivated under glass or foil.
This type of vegetable is highly recommended for summer use in cold frames and small greenhouses. Here the plants are protected from rain and too much cooling at night and can develop without stunted growth. In the cold frame, the windows must be raised, once the plants are that big, that they almost hit the glass. To do this, posts are driven into the long sides of the cold frame and connected with slats, where the windows come to rest. The plants are airy and yet protected from the weather. By the way, building over with cold frames or with foil-covered wooden frames is also recommended outdoors. It is sufficient, when the slide – or glass protection is about 80cm above the ground. The windows or. Foil frames remain over the plants throughout vegetation. There is no shading, since eggplants require full light.
