How To Make A Garden Pond

Hello there! Are you ready to turn your garden into a haven for wildlife and a peaceful retreat? Creating a garden pond is the perfect DIY project for you. Not only will it provide a beautiful addition to your outdoor space, but it will also become a thriving ecosystem for plants and animals. In this step-by-step guide, I will show you how to make a garden pond that will bring joy and tranquility to your life.

Key Takeaways:

  • Creating a garden pond is a rewarding DIY project that brings wildlife and serenity to your backyard.
  • Mark out the pond shape using a length of rope or hosepipe.
  • Remove the turf carefully and save it to secure the liner around the pond.
  • Dig the pond to the right depth, ensuring plenty of shallow basins for wildlife.
  • Check the level of the pond using a spirit level for a neat finish.

Step 1: Mark out the pond shape

Before you begin the exciting process of building your garden pond, it’s important to mark out its shape. This initial step sets the foundation for the rest of the construction process.

To mark out the shape of your pond, you can use a variety of tools like a length of rope, hosepipe, string between sticks, or bamboo canes. By shaping the outline, you can visualize how the pond will fit into your garden landscape.

Depending on your personal preference and the style of your garden, you can choose between a natural or formal pond shape. A natural shape mimics the irregularity of a pond found in nature and can create a more organic and relaxed feel. On the other hand, a formal shape, such as a rectangular or circular design, offers a more structured and symmetrical appearance.

Remember to consider the size and proportion of your garden when determining the pond shape. Ensure it complements your existing landscaping and fits harmoniously into the overall design.

Why Marking out the Pond Shape is Important

Marking out the pond shape is a crucial step in your DIY pond building journey. It allows you to:

  • Visualize the placement and size of the pond in your garden
  • Ensure the pond shape harmonizes with your existing landscape
  • Have a clear guide for digging and shaping the pond

By taking the time to mark out the pond shape accurately, you lay the groundwork for a successful garden pond construction project.

Step 2: Remove the turf

Now that you have marked out the shape of your garden pond, it’s time to get your hands dirty and start digging. The first step is to remove the turf from the designated area.

Using a sharp spade or turf cutter, carefully cut and lift the turf, creating neat edges around the pond perimeter. Keep the pieces of turf aside as you will need them later to secure the liner around the edge of the pond.

Pro tip: Instead of discarding the turf, consider using it in other areas of your garden or composting it to enrich your soil.

Removing the turf is an essential step in garden pond construction as it allows you to create a clean and stable base for the pond. Additionally, avoiding the use of turf inside the pond prevents the introduction of any potential contaminants or excess nutrients that can negatively affect the water quality and harm the plants and wildlife.

Remember, a healthy and balanced backyard water feature relies on maintaining a clean and pollutant-free environment.


“Removing the turf not only helps prepare the site for your garden pond but also ensures that the water remains in its purest form, providing a safe haven for wildlife to thrive.” – David Wilson, a professional landscaper.

With the turf out of the way, you are now ready to move on to the next step of your DIY pond building adventure.

Step 3: Dig to the right depth

When constructing a garden pond, it’s important to dig to the appropriate depth to create the ideal habitat for wildlife. A well-designed pond with varying depths provides a supportive environment for various plants and animals.

Tadpoles and other pond wildlife thrive in shallow basins, so be sure to incorporate plenty of shallow areas when digging your pond. Aim for a depth of no more than 30 cm, with approximately 50% of the pond designated as shallow water.

Here’s a step-by-step guide to help you dig your pond to the right depth:

  1. Start by marking out the desired shape of your pond as discussed in the previous section. This will serve as a guide for your digging.
  2. With a spade or shovel, carefully begin digging within the marked area, working your way outwards towards the edges.
  3. As you dig, measure the depth at different sections of the pond to ensure consistency. This will help maintain a balanced ecosystem.
  4. Keep in mind the 50% shallow-to-deep ratio to provide ample habitat for wildlife.

By digging to the right depth and incorporating shallow basins into your pond design, you’ll create a welcoming space for frogs, dragonflies, and other wildlife to thrive in your garden.

I found that creating different depths in my garden pond made a noticeable difference in the variety of wildlife it attracted. Watching the tadpoles and dragonflies flourish in the shallow areas has been truly fascinating.

Benefits of Digging to the Right Depth Considerations
Provides habitat for diverse wildlife Digging too deep may make it challenging for certain species to thrive
Encourages natural water filtration and oxygenation Shallow areas may require more frequent cleaning to prevent stagnation
Creates a harmonious ecosystem with a range of plant species Deeper areas may require additional precautions for safety, especially if children are present

Step 4: Create shallow basins

If you want to create a thriving ecosystem in your garden pond, it’s crucial to ensure the right depth for pond wildlife. Most garden ponds are too deep, which can limit the diversity of plants and animals that can inhabit them. By creating shallow basins, you can provide a more suitable habitat for a variety of pond life. Here’s how:

  1. Design a Gentler Grass Edge:

The first step is to shape the grass edge of your pond in a gentler manner. Instead of a steep drop, create a gradual slope from the water’s edge towards the surrounding soil. This will allow creatures like frogs and newts to easily enter and exit the pond without struggling or getting trapped.

  1. Raise a Rim of Turf:

To further enhance the shallow areas of your pond, raise a rim of turf around the perimeter. This will help retain water and create a more natural appearance. Simply remove the sod around the edge and carefully fold it inward, securing it with stakes or rocks. Make sure the turf is slightly lower than the desired water level to prevent any overflow.

“Creating a gentler grass edge and a rim of turf is essential to mimic the natural conditions found in many pond ecosystems. This allows for a wider variety of plants and creatures to thrive and provides a more visually appealing pond.” – Pond enthusiast, Jane Smith

The Benefits of Shallow Basins

Creating shallow basins in your garden pond offers numerous benefits, not only for wildlife but also for the overall aesthetics of your outdoor space. Here are some key advantages:

  • Promotes biodiversity by attracting a wider range of species
  • Allows for the growth of diverse aquatic plants, such as water lilies and marginal plants
  • Supports breeding and nesting activities of amphibians and insects
  • Provides a safe and accessible drinking spot for birds and other small animals
  • Encourages a more natural and visually appealing pond design
Species Preferred Habitat Depth
Frogs 10-20 cm
Newts 15-30 cm
Dragonflies 10-30 cm
Water Beetles 10-20 cm

By incorporating these shallow basins into your pond construction, you’ll create a thriving environment that attracts a wide array of fascinating wildlife.

Step 5: Check the level

Before moving forward with your garden pond construction project, it’s crucial to check the level of the pond. Ensuring a level surface will prevent water from running out and create a neat, finished look. Plus, a level pond contributes to the overall aesthetics of your garden.

Use a reliable tool like a spirit level to accurately assess the level of your pond. This will help you determine if any adjustments or corrections are necessary.
