This makes it possible for a double or triple-level water feature to be created. In a typical case, water would be pumped from a lower barrel up into a decorative hand-pump attached to the upper barrel. From the hand-pump, the water falls into the upper barrel. The water then cascades out of the upper barrel down to a second, lower barrel. A double-level garden like this can form an attractive centerpiece to a deck or patio.
Some people prefer to have multiple barrel gardens arranged in a row or in some creative design.
Six or eight barrels, each containing blooming waterlilies, can make a stunning edge for a deck or border for a patio. Many water features are available for the barrel garden. The pumps are available in several styles and materials. Watering cans and water buckets can be hung from the hand-pump for added decoration. The hand-pump is usually mounted on a bracket at the edge of the barrel.
