Box or tubular casings (also plant protection casings, protective pants) at a height between 35 and 80 centimeters, which are pressed into the ground and fixed to the planting stick. This will make the Rebstock fairly tightly encased to the desired height. It is very important that the casings are firmly anchored in the floor (at least 15 to 20 centimeters deep), otherwise there will be a negative chimney effect. High-quality cardboard or plastic is used as the material, individual brands have a low aluminum content (such as packaging in the beverage industry) and are reusable. There are also translucent materials that are required in certain wine growing areas. In the New world Such planting aids have been used in young plants and new plantings since the early 1990s. There were trial applications in Europe, for example in the German growing regions Rheinhessen and Moselle, in Austria as in Luxembourg,
Such plant tubes offer protection against many vine pests fungal infection such as wrong mildew and before game browsing, This means that far fewer plant protection measures are required. A "microclimate effect" is created inside the tube. This promotes growth and faster expulsion of the main shoot within the tube after the leakage Triebes then a reduced or normal growth occurs again from the shell. It will also make the formation of unwanted suckers prevented. Based on previous experience, the "correct" height of these plant protection covers plays an important role. Various products are available commercially, for example the Groguard, Tubex and VitiPack brands.
