Fiskars Self-watering Planter reduces how often you have to water and still improves the health of your plant. A built-in reservoir holds water in the bottom of the planter, and specially designed soil channels draw up water and oxygen for the roots. This keeps your plants healthy by supplying consistent moisture, preventing plant-killing root rot and preventing the loss of nutrients that traditional pots experience. Lightweight planter includes UV-protection and all-weather durability for lasting value.
