With the 4 clay cones, you can automatically supply plants with water during the day during a hot summer. The permeable material releases doses of water to potted plants, flower pots or raised beds to keep the soil moist. Simply sink the watering aids into the soil or dig them in up to the edge and then pour water in through the opening. Now you can pursue your plans without any worries while your green treasures are safely watered. Please note: The clay spikes are designed to be filled directly with water and are not suitable for bottles . When inserting the watering aids into the soil, please do not use a hammer or similar, but only screw them in by hand. The watering spouts are not winterproof.
