Abstract
An improved sub-irrigation system for container nursery stock wherein liquid rises by capillarity through small pores in the growth medium in the container so that the larger pores of the growth medium retain air. The sub-irrigation system comprises at least one container and a trough assembly. The container, which is constructed to receive and retain growth medium and one or more plants therein, is provided with a drain opening and a spatially disposed inlet port in a lower portion thereof; and the trough assembly is provided with an outwardly extending leg positionable through the inlet port of the container so that controlled amounts of liquid can be discharged into the growth medium for capillary movement therethrough and absorption by the roots of the plants in the container.
