Choose a spot for the pond where it will get sun and shade throughout the day. Sun is necessary to keep the pond healthy, but too much means that algae could overgrow. [3] X Research source
Large and elaborate ponds can be over 300 sq ft (28 m2).
Deeper ponds are able to maintain more consistent temperature ranges. This is ideal if you are wanting fish. [6] X Research source
If you need, mark out the shape on the ground first to experiment with different designs. Use rope, a hose, or spray paint. This will also provide a guideline when it comes to digging the pond. [8] X Research source
The terraces look like small steps along the side of the pond. These provide a flat surface for the plants and you only need to dig these where you are planning to put the plants. An ideal size for each terrace is 1 by 1 ft (30 by 30 cm) and 8 in (20 cm) deep. You can hire a professional to use an excavator to dig the pond if you don’t want to dig it by hand.
If you want an extra layer of protection, roll out a piece of old carpet over the layer of sand.
Pond liners keep the water contained in the pond. These are made out of EPDM and polypropylene and are very weather resistant. Pond liners are heavy enough to remain in place and are unlikely to be moved by the wind. If you have concerns, use a few rocks or large stones to hold the liner in place. Make sure that the pond liner is rated as fish-safe if you are going to be placing fish in the pond. [12] X Research source
Pond filters keep the fish healthy, the water clean, and prevent bad odors. You can place plants around the filter box to keep it hidden if you prefer. [15] X Research source
If you are planning to have fish in your pond, add dechlorinator to the water to ensure that it will be safe for the fish. [18] X Research source
This is where you can start to get creative and begin landscaping the area around the pond. Experiment with different designs and ways of stacking the rocks until they look just right. The rocks can be a range of different sizes and types. Some ponds are edged with large rocks that are over 3 ft (0. 91 m) long, while other ponds use smaller rocks that are approximately 1 ft (0. 30 m) long. [20] X Research source
Cattail, lotus, iris, and water hyacinth are all ideal pond plants. [22] X Research source Good options for plants to place around the pond include cow parsley, yarrow, and teasel. [23] X Research source Goldfish, koi, trout, and tilapia all do well in backyard ponds. [24] X Research source
