PROBLEM TO BE SOLVED: To provide a plant watering device enabling a plant to be watered at any levels by utilizing empty plastic bottle(s) in the absence of any person, enabling the plant to be entirely watered by laying the plastic bottle(s) sideways, or enabling water supply from a single plastic bottle to at least one water supply point or from at least one plastic bottle to a single water supply point. SOLUTION: This plant watering device has the following scheme and mechanism: a pipe is penetrated through the plastic bottle, the inside pipe port is tightened with a lid or stopper connected with a bellows-bearing tube, and the resultant plastic bottle is laid sideways; the tip port of the tube is fixed at the flank bottom of the bottle, and together with a water supply tube linked outside, a parabolic-trajectory-shaped water pathway through which water can be discharged based on the siphon principle is formed; a watering vessel is connected to the tip of the water supply tube, functioning to water the plant by producing a water pool therein and issuing water driplets via small holes on the surface thereof, the watering level depending on both the size and number of the small holes; if the water supply tube to be used is branched, water division/collection can easily be accomplished.
