Abstract: A pot assembly for cultivating sprawling plants, such as orchids and Phalaenopsis includes an inner pot and an outer pot. It is proposed to fit an outer pot at the point in time when such plants are being placed in the inner pot. All this is carried out in such a manner that plant parts which project from the inner pot cannot extend into the space between the inner pot and outer pot, while the outer pot ensures that the plant parts do not extend outside the outer pot in an uncontrolled manner. Cultivation takes place in the pot assembly consisting of inner pot and outer pot and, at the end of the growing phase, the inner pot and outer pot are separated and the outer pot is preferably re-used. The assembly makes it possible to automate the cultivation and/or influence the development of the plant in a positive manner.
