The invention relates to agriculture, and is designed for automatic irrigation as a garden and garden and houseplants. The apparatus does not include electronic and electrical products, and all parts of the device can be made of plastic by injection molding. Further watering device subject to weather conditions: air temperature and humidity, rainfall. The apparatus comprises a clamp-evaporator, consisting of a housing equipped with focusing and outlet and the evaporating tray equipped with focusing and counterweight. The tray is suspended within the housing of the evaporator-clip on the axle, providing swing tray in a vertical plane. Between the casing and stops the tray, directed towards each other, passes the elastic tube, which leads the water from the water source to the water flow divider. The divider equipped with discharge outlets, disposed beam having a double-capacity bucket with rocker rocking axis in the vertical plane, providing two rocker free rest position. swing axis of the rocker is suspended in a divider on the turntable, ensuring the possibility of rotation of the rocker with the platform in a horizontal plane around the platform axis. This rotational movement provides Coronaform helical guide, located in the divider along the radius from the rotation axis of the platform. Each inverted from one position to another rest free rocker under the action of gravity forces the water to slide along the rail, providing the platform rotate together with a yoke at one step of the guide. So step by step, the water is distributed between the discharge outlets divider. One of the outlets is directed to the dosing siphon, which measures a single irrigation rate per plant. Water outlet of the siphon in turn sent to the evaporation tray. When triggered siphon water tray under the force of gravity is lowered and pinched between the abutments elastic tube, stopping the water supply to the divider, thereby, completing the watering cycle. Watering is stopped and the ra
