Abstract: A plant watering device comprises a receptacle for water with a tube extending downwardly from the receptacle. The tube is packed with a fibrous or particulate medium which permits water to percolate downwardly through it. The lower end of the tube is of spike form to enable it to be pushed into the ground. The upper end of the tube communicates with the receptacle so that water flows into the tube from the receptacle. Below the receptacle the tube has one or more outlets so that water percolating down the tube can escape into the surrounding earth.
