A self-watering planter is a gardening container designed to provide plants with a consistent supply of water. It typically features a reservoir at the bottom that holds water, allowing plants to absorb moisture through a wicking system or drainage holes. This design 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. Self-watering planters can be used for various types of plants, including herbs, flowers, and vegetables, promoting better growth and reducing maintenance efforts.
