Building a beautiful pond in your garden is nowhere near as difficult as you might imagine. In fact, it’s the perfect weekend DIY project!
To determine how big your pond can be, you will need to take into account the size of the area the pond will go into. The larger the space, the larger your pond can be. However, if you’re planning to create a really big pond, you may need to check your with your local council to see if there are any restrictions on the size and depth of an unfenced pond. We recommend a pond size approximately 1.2 metres by 2.4 metres, and about 30cm deep.
You should also consider your budget. While creating a larger pond will not cost too much more, adding water plants and water features will. Water plants require a deeper pond – water lilies, for example, require a minimum depth of 40cm. Water features will also cost more depending on the size and style.
Now you’ve got the logistics sorted, let’s get started.
1. First you’ll need to determine the location of your pond. Envision how your pond will fit in to the area, and approximate its shape with paint, chalk, or string.
2. Now you have to dig! Dig down to your desired depth, keeping the edges as vertical as possible.
3. Once you’ve got a nice, even hole, you’ll need to lay some material, such as newspaper or old carpet, over the bottom. This will protect the liner from becoming damaged by sticks or rocks.
4. You’re now ready to line your pond. You can purchase pond liner from a hardware store. To calculate how much liner you will need, use this equation: pond liner = (depth x 2) + (length + 60cm). So that’s two times the depth, plus the length, plus 60cm. Line the bottom of your pond, and fill it with about 15cm of water. Leave this overnight to allow the soil to settle.
5. The following day, trim the liner until it is about 10cm larger than the pond. If you are including a pump water feature, install this now.
6. Now you want to cover the edge of the liner with rocks. You can use rocks from your garden, or purchase some from your local hardware. You can even use old slate floor tiles smashed with hammer. Use smaller rocks to fill in the gaps. You can also line the bottom with stones, though this isn’t necessary.
7. Fill the remainder of your pond with water, and position your water feature on a brick to ensure it’s the right height. You can add plants and sculptures to the perimeter of your pond, too.
8. If you have used a pump action water feature that consistently breaks the surface of the water, your pond should be safe for goldfish.
9. You can keep most water plants in their pots. Unless the plant label says otherwise, place the pot on the bottom of your pond, and allow the plant to float to the surface.
And there you have it – a quick, easy, inexpensive way to create a stunning garden feature. Enjoy!
