A sink garden can be called a basin garden, container garden, or even a planter garden. The concept behind a sink garden is to use an old or discarded sink as a container for growing plants. However, if sinks are not available, other containers can be used such as a bucket, watering can, or an old bathtub. Sink gardens are great because they are small and can be placed almost anywhere. They are perfect for growing vegetables, herbs, and even flowers. With a little bit of creativity, a sink garden can add a unique touch to any space, making it a wonderful addition to any gardening project.
