Worlds first Bamboo Fiber self-watering pot this 16″ Herbs Rectangular self-watering planter is made from sustainable biodegradable all natural Bamboo Fiber and corn starch. Plants thrive in this natural Bamboo Fiber planter that is plastic free. The soil is better aerated by the unique water well in the base allowing better nutrient management helping the plants grow healthy and strong. These planters should be treated like ceramic suitable for use in hot or cold climates inside or outside. At initial planting water from the top until water is just below the overflow. Then periodically check the water level in the base and add water to the well from the bottom access or from the top of the planter. The soil draws water up from the well as needed using capillary action just like a wick. No more overwatering strong healthy plants is the result! Everyone gets a “green thumb” growing in bamboo planters and just by keeping water in the well! When you are finished with your planter just break it up and put into your compost bin. Over time the material will degrade back to nature.
