A self-watering bird feeder provides a steady, controlled release of water directly into the soil. Once inserted into the compost, the ball gradually dispenses water as the soil dries out, helping maintain consistent moisture levels. Ideal for houseplants that prefer evenly moist soil, it reduces the risk of overwatering and is especially useful during holidays or busy periods. It works best in well-draining compost and should be refilled as needed depending on plant size and environment. A simple way to support healthier root systems and more stable growth.
