Why You Should Create a Pond in Your Garden
Creating a pond in your garden isn't just about making it pretty (although that's a great reason); it's also a fantastic way to support local biodiversity. A pond attracts various birds, insects, and other wildlife, providing them with a crucial water source and habitat. Birds will visit for a drink and a bath, while insects like dragonflies and butterflies are drawn to the water's edge. Frogs may also make your pond their home, helping to control insect populations naturally. Best of all, by adding a pond, you contribute to a healthier ecosystem in your garden.

Before you begin, gather the following materials:
- Concrete edging stones (we used three, adjoined to the existing deck at one end)
- Concrete (for the joints)
- Wood for the frame
- Pond fleece
- Black Pond liner
- Screws (anti-rust)
- Drill
- Extra decking wood (preferably matching your existing decking)
- Large and small stones (for inside the pond)
- Solar-operated pump with filter and fountain feature
- Pond plants
- Pond plant containers
- Aquarium gravel
- Edging stones (optional)
Measuring and Planning
To ensure your above-ground pond blends seamlessly with your deck, start by measuring the height of your deck. This will help you determine the correct height for your pond. Don't forget to account for the thickness of the pond fleece, liner, and wooden supports and trim. (Read more about that below).
Building the Base
Concrete Edging Stones
Begin by placing the concrete edging stones against your deck or patio to form the base of your pond. If they are too high, dig them into the ground a little so they are at the right height once the fleece and liner are added. 'Weld' the joints with concrete and allow the concrete to set. This foundation will provide stability and structure to your above-ground pond. For our project, the pond was 100 x 90 cm (approximately 39.4 x 35.4 inches).
Wood trim
We added wood to the top of the edging stones to bring the pond to the level of the deck. If you need to do this, remember to account for the fleece, pond liner, and wood trim. The end result should be that the wood trim on your pond is perfectly level with your existing deck or patio.
Pond Fleece
Lay the pond fleece inside the pond, ensuring that the corners are neat and fit flat against the concrete blocks. This layer protects the liner from sharp objects like stones and adds insulation to your above-ground pond. You could use an old carpet for this instead of fleece.
Pond Liner
Next, place the pond liner over the fleece. Smooth out any wrinkles and again, make sure the corners are neatly folded. The liner holds the water and stops it from leaking out of your pond.
Assembling the Pond
Securing the Liner
Use anti-rust screws to secure the fleece and liner to the concrete edging stones. Trim any excess material to fit the pond perfectly. Instead of trimming the liner and fleece to the top of the concrete supports as we did, you could fold them over the concrete supports and secure them with the wood trimming plank.
Cladding the Sides
Attach wood decking pieces to the sides of the pond to match your existing deck if possible. This step will give your deck and pond a cohesive look, although as it ages, the wood will develop a beautiful natural patina anyway.
Adding the Top Decking
Fix additional decking pieces on top of the pond to join it to your deck and make it appear as an extension of your patio.
Decorating the Pond
Stones for a raised pond
Place stones at the bottom of the pond (the images show white stones, but we ended up exchanging those for black slate). Pile larger stones at one end to create a natural, varied terrain. These stones also provide hiding spots for aquatic life.
Installing a Pond Fountain and Pump
We installed a solar bubble fountain with an integrated pump. A pump helps oxygenate the water, keeping it healthy for plants and any potential fish.
Our fountain has five unique sprinkler options but we keep ours on the bubble option because we love the sound it makes. Also, our above-ground pond is so small that some of the sprinkler options sprinkle water outside the pond. It's worth thinking about that when purchasing a pond sprinkler or fountain for a small pond. The reach of the fountain should be stated in the description.
Filling a Raised Pond with Water
Fill the pond with water. While rainwater is best because of its low nutrient content, tap water can be used if rainwater is unavailable. If algae blooms occur, use algae control to clear the water. String algae started to form in our pond, but a tiny amount of algae powder was all it took to clear the water.
Oxygenation and Planting
Oxygenation: Ponds need oxygen for the health of plants and aquatic life. A small patio pond can be oxygenated using water features like fountains or waterfalls, which keep the water moving. Alternatively, adding an air pump can increase oxygen levels.
Planting
Choose a variety of pond plants for visual interest and ecosystem balance. Repot the plants into larger pond plant baskets using pond planting soil. It's important not to use regular garden soil in a pond because it has too many nutrients and encourages algae blooms.
Add aquarium gravel around the plant bases to prevent soil from escaping and clouding the water. Pay attention to the area for which the plant is suitable because some need to be planted in much deeper water.
If you use marsh plants as we did, stand them on bricks or stones, elevating them toward the pond surface.
Acclimatizing Pond Plants
After purchasing your pond plants, especially floating varieties, it’s important to acclimatize them to their new environment to ensure they thrive. Place the plants in a bucket filled with pond water for about an hour. This helps them adjust to the temperature and pH of your pond.
How to prevent pond plants from scorching
While researching the best pond plants for a mini pond, I came across so many comments from people saying that they had bought floating plants only to have them die from scorching immediately after introducing them to the pond. In each case, it was clear that the plants had been added to the pond without acclimatizing them first.
If your plants were kept indoors at a garden center or in a shaded area before purchase, they should be gradually introduced to sunlight to prevent scorching. Plants can easily scorch if exposed to full sun too quickly, as their leaves are not yet adapted to intense light.
To acclimatize your pond plants, or floating plants, place them in a bucket of pond water in a shady area or on the north side of your house for a few days before moving them to your patio pond. This gradual process minimizes shock and promotes healthy growth. We made sure to acclimatize our pond plants and have had no problems with scorching at all. I know it's hard to wait (at least it was for me), but it's better than having your pond plants die within a few days.
Preventing Mosquitoes
Mosquitoes can be a nuisance in any pond. To prevent them from breeding, use a water feature that keeps the water moving, as mosquitoes prefer stagnant water. Additionally, you could use a pond net to remove mosquito larvae. Introducing fish that eat mosquito larvae can also be effective.
Final Touches
To complete your above-ground pond project, surround the pond and the edge of your deck with small stones that complement your garden color scheme. To soften the border, we planted Spanish daisies around the base of the pond to add a splash of color and blend the pond with our garden.
Preparing an above-ground pond for fish
We haven't added fish to our pond yet, but we have researched it, which I'm passing on here. If you're considering adding some fish to your pond, you'll need to make a few additional preparations to ensure the pond is healthy for them. First, choose fish species known for their mosquito control abilities, such as mosquito fish (Gambusia affinis), guppies, or goldfish. These fish thrive in small ponds and can significantly reduce mosquito larvae.
Preparations:
- Filtration System: Install a robust filtration system to maintain clean water, as fish produce waste that can affect water quality. A solar-operated pump with a filter should keep the water clear and oxygenated.
- Shelter and Hiding Spots: If you haven't done so already, add some aquatic plants and stones to create shelter and hiding spots. Plants add more interest to your patio pond and provide a natural habitat for the fish. Plants also help oxygenate the water and absorb excess nutrients, creating a healthier environment for your fish.
- Water Quality Monitoring: You will need to check the water quality regularly, to make sure the mini pond has the proper pH levels and cleanliness. Use a pond test kit to monitor ammonia, nitrite, and nitrate levels to keep the water safe for your fish.
- Overwintering Fish: The thing about having a pond above ground is that it could freeze in Winter. In this case, transfer any fish to an indoor aquarium during this time.
Enjoying Your Pond
There's something truly magical about sitting beside your newly built pond, listening to the gentle bubble of the fountain, and feeling the breeze on your face. It's the perfect spot for quiet reflection, where you can journal, jot down ideas for your next garden project, or dream up new ways to beautify your outdoor space. Maybe you'll sketch out plans for a cozy seating area or brainstorm a list of plants you'd love to add. Or perhaps you'll simply sit with a cup of tea, soaking up the tranquility and letting your mind wander.
This little raised garden pond you’ve created is more than just a water feature; it’s a sanctuary where inspiration and peace flow as freely as the water.
Do you remember what I said in the first paragraph of this post about the coffee, the water, and the plants? Well, that's me every day now that I have my patio pond. I find it very relaxing to sit there, even if I only have five to ten minutes to spare.
