A plant irrigation system and method of use, wherein the system accepts a fluid and releases it over time to one or more plants. The system can be fed manually or via an irrigation network capable of feeding fluid to one or more containers. The irrigation network can feed fluid automatically or manually. Fluid flow into each individual container is controlled via a float valve or level switch. Fluid exits the container and waters the ground immediately below via a fluid release valve that can be manually set, regulating the flowrate out of the container. The containers are above the ground, each mounted upon a stake, and utilize a flexible impermeable membrane.
