Self-watering planters are gardening containers designed to provide plants with a consistent supply of moisture. They typically feature a reservoir at the bottom that holds water, allowing plants to absorb it through a wicking system or drainage holes. This helps prevent overwatering and underwatering, making it easier for gardeners to maintain healthy plants. These planters are especially useful for busy individuals or those who travel frequently, as they reduce the need for daily watering. Available in various sizes and styles, self-watering planters can accommodate a wide range of plants, from herbs to flowers and even small vegetables.
