A plant irrigation apparatus for providing a fluid to one or more plants includes a plurality of platforms that are disposed in an array. Each platform has a support surface that is disposed at a platform elevation. A fluid reservoir for containing the fluid is defined at least partially in between adjacent platforms of the plurality of platforms. At least one fluid-regulating structure is configured to maintain a maximum elevation for the fluid, wherein the maximum elevation for the fluid is lower than the platform elevation. A capillary mat is supported by the plurality of platforms. At least a portion of the capillary mat is disposed within the fluid reservoir below the maximum elevation of the fluid.
