A plant pot assembly (1) comprises a first pot (3) for a plant (7) in growing medium (9), a second pot (11) coupled to it for forming a liquid reservoir (15), and a wick (17) between the liquid reservoir and the first pot for transporting liquid from the liquid reservoir into the first pot. The liquid reservoir has a filling opening (21) at or near the upper side of the assembly and wherein the first pot is received in the second pot with a close fit so that the liquid reservoir is situated substantially below the first pot. The wick extends between the first and second pots and protrudes near an upper edge of the first pot into the first pot, and extends in it. The first pot is substantially watertight and the assembly is arranged to prevent liquid transport between the reservoir and the growing medium via another route than the wick.
