Plant container irrigation apparatus 10 includes a master controller 12 for controlling irrigation of a plant container 14. The apparatus includes an irrigation liquid transport arrangement 16 for transporting irrigation liquid 18 from an irrigation liquid supply 20 to the plant container. The transport arrangement includes a flow controller 22 for controlling the flow of the irrigation liquid to the plant container, the flow controller being movable between a flow condition, in which the flow controller permits the irrigation liquid to flow to the plant container, and a non-flow condition, in which the flow controller does not permit flow of the irrigation liquid to the plant container. The apparatus includes a run-off detector 24 which, in use, detects irrigation liquid run-off 26 from the plant container and provides a run-off detection signal to the master controller. The master controller is arranged so that receipt of the run-off detection signal causes the flow controller to move from the flow condition to the non-flow condition. Also disclosed is a method of irrigating a plant container.
