Patent ID: 7082716

Claim:
A device for watering vegetation comprising (A) a cylindrical tube having two ends and opposing inside surfaces, where the opposing inside surfaces do not contact each other except about 2 to about 6 inches from each end of said tube, where a watertight seal that extends from the bottom of said tube to the top of said tube is formed between opposing surfaces of the inside of said tube, forming a compartment inside said tube and leaving a flap of said tube about 2 to about 6 inches long at each end of said tube; (B) horizontal slits extending part of the way across said flaps, whereby one or more stakes are inserted through said slits and said stakes hold top ends of said tube higher than rest of said tube, the bottom of said tube substantially contacts the ground surface; (C) one or two openings into said compartment at or near said seals where said top ends of said tube are higher than any other top portion of said tube between said seals, through which water can be admitted into said compartment; and (D) at least one drip emitter in said compartment, at or near the bottom of said tube, from which water exits said tube, whereby when said tube is filled with water said tube assumes a cross-sectional shape that is wider than it is high and when said tube is empty it may be laid flat and rolled up.
