Smart PotŪ Pond Pots give your pond plants a natural home in which to grow. The porous, breathable fabric allows water to pass through the Pond Pot, bringing oxygen to the plant's roots and promoting healthy growth. The Pond Pot fabric keeps soil in and conforms to sloping or uneven pond floors. The Pond Pots are much safer for fish and other aquatic life since there are no cracked or sharp edges.
