Pond in a Bucket
Create this easy water garden on your deck or patio in a few hours. This pond takes only a few hours to make, and it can be made out of nearly anything that holds water.
Oak barrels, old sinks, or bathtubs can all make fine backyard ponds. One of the easiest container pond gardens is made from a stainless steel sitz bath—they don't require an extra liner. This project is so easy to assemble that you can gather your supplies on Saturday morning, fill the pond with water in the afternoon, and launch the fish into their home after waiting 48 hours for the chlorine to disperse.
Like a natural pond, container ponds depend on a delicate balance of plants, snails, tadpoles, and fish. You can also use a pump or a filter instead of water creatures to keep the water fresh. Use oxygenating grasses (which add oxygen to the water) and floating plants such as water hyacinths (which provide hiding space among their roots for pond creatures). When winter comes, plants sit underwater on the bottom of the pond; fish and tadpoles winter inside.
