A method for cultivating a plurality of young plants of different species or variety to form a group of young plants which can be handled as a unit. The method includes providing a plurality of propagation pots, each containing a substrate, which allow roots that form in a propagation pot to grow out at the sides, loading at least one growing container with the plurality of propagation pots such that the propagation pots arranged in each growing container contact one another along a portion of their lateral peripheral surface, introducing at least one cutting or seed into each propagation pot, and allowing roots to form in the propagation pots of each growing container until roots emerging from the sides of the propagation pots have formed a network of roots binding the propagation pots together as a cluster of propagation pots.
