The object of the invention is a plant cultivation container, wherein the plants do not need to be transplanted during cultivation or growth. The container is provided with pull-out trays and this allows continuous adaptation of the container volume to the growth and development of the root system. The container of the invention provides for continuous oxygen and air supply to the root system and for development of fibrous roots contrary to root spiralisation which is typical of conventional containers. The pull-out tray has several functions: partitioning of container volume to compartments, retaining of excess water while watering, and as a drip tray when the entire container volume is in use. The walls of the container are provided with notches at various heights which in conjunction with several pull-out trays partition the entire volume of the container along its height to several compartments. The notches are sized in a way to adapt to the thickness and height of the side walls and the bottom of a pull-out tray when the trays are inserted into the notches. The pull-out trays are simply insertable into and removable from the notches and this is why the container volume can simply be adapted to the growth and development of the root system.L'invention concerne un récipient de culture de plantes, grâce auquel les plantes n'ont pas besoin d'être transplantées pendant la culture ou la croissance. Le récipient est pourvu de plateaux escamotables, ce qui permet une adaptation continue du volume du récipient à la croissance et au développement du système racinaire. Le récipient selon l'invention permet l'apport continu d'oxygène et d'air au système racinaire et le développement de racines fibreuses, à la différence de la spiralisation des racines qui est typique des récipients classiques. Le plateau escamotable a plusieurs fonctions : la séparation du volume du conteneur en compartiments, la rétention de l'eau en excès lors de l'arrosage, et comme plateau d'égouttage
