Abstract
A subirrigation mat has a substrate covering an area across which several potted plants are to be irrigated. Connected along the substrate are a plurality of channel members upon which the plant containers sit. A main conduit connected at respective open ends of the channel members provides irrigating fluid concurrently to each channel member. This fluid flows through outlet holes in the channel members and into the containers placed above the holes. A valve can be associated with each outlet hole to close it when a container is not placed above the hole. A cup can be associated with each outlet hole or valve to facilitate communication between the hole in the channel member and the hole in the bottom of the container.
