摘要：

A device for planting trees, large shrubs and the like has a substructure which can be lowered into the ground, closes off the planting trench laterally and comprises one or more prefabricated concrete compound units. The prefabricated concrete compound units have, in the side wall, through-passages through which the roots can grow. The through-passages are closed up by a decomposable material through which roots can penetrate.
