Unitized mat to facilitate growing woody plants

A unitized mat to facilitate growing woody plants, comprising:

• at least two polymeric material layers sized and shaped to cover an area immediately around at least one plant and selectively bonded together to define fluid-conveying passageways forming at least one distribution header and at least one flow restricting means, the polymeric material layers having a plurality of perforations extending therethrough;
• an inlet means for delivery of a fluid into a first distribution header through the polymeric material layers, said inlet means being in fluid communication with the first distribution header, said flow restricting means extending outwardly from said first distribution header;
• and
• an outlet means for dispensing fluid into a root zone area covered by at least one layer of said polymeric material layers and positioned at the perforations, said outlet means being in fluid communication with a second distribution header, said flow restricting means throughout the polymeric material layers being in fluid communication between said first distribution header and said second distribution header, said flow restricting means extending outwardly from said first distribution header to said second distribution header, said outlet means having multiple outlet ports being positioned at said perforations.
