Filling a mini pond

Make a mini-pond

Every wild garden benefits from having a pond. Make a splash for nature near you by creating your own!

Birds bathe in it, dragonflies lay there eggs there, newts get a wiggle on among the water weed. Ponds are a fantastic addition to any garden and a great way to give nature a home.

You don't have to have a huge outdoor space to make a pond. If you do have a big garden, you can try your hand at a large pond, but a mini-pond is something nearly anyone can do.

It doesn't matter whether you've got a small balcony or a tiny backyard, everyone can bring a little bit of water into the lives of the wildlife around them!

It's a fun activity that the whole family can get involved with and can be the start of many more garden adventures to come!

What you will need

  • A large water tight container, like an old sink or big washing up bowl, or even a purpose built rigid liner.  
  • Pond plants. Here's a selection which are perfect for a mini-pond:

To go under the waterrigid hornwort, whorled water-milfoil, water-                       soldier, water starwort.

To poke out of the water: lesser spearwort, Equisetum                                                 hyemale, brooklime, water-plantain, iris versocolor, iris laevigata

  • The base of the pond should have a bit of sand or gravel.
  • Camera or smart phone

Step-by-step

  1. Find or buy a large container. It could be a half-barrel, an old Belfast butler sink, or even your mum and dad's old washing-up bowl! (Although we can't promise this will get you out of doing the washing up!)

    It needs to be strong if it's going to live outside, especially during frosts.

    You could use something that isn't watertight but is strong, such as a large plant pot, but making sure that it doesn't leak can be tricky. If you do use a pot, you may want to consider lining it with pond liner - otherwise you'll end up with a pond with no water!

  2. Put your container into your chosen place while it’s empty. Once it’s full of water, it will be very hard to move without spilling it all over the floor!

    Ideally you’ll put it somewhere that gets a good amount of light, but isn't in full sunlight all day.

    You can sink it into the ground or leave it proud of the surface, but if the edges are level with the ground, more creatures can get in and out.
  3. Even a mini-pond can be a hazard for small children, so position it where it will be safe.
  4. Prepare your pond. Seal any drainage holes. After all, a pond with holes isn't going to be a very good pond!

    If you’re using an old sink, ask an adult to help you silicon a plug into the plughole. If using a large plantpot line it with butyl pond-liner, although be aware that folding it around right-angle corners is tricky - like a difficult origami!

    Put a layer of clean gravel in the bottom if you wish. Don't use soil  it is too full of nutrients and it will help slimy-green algae to take over!

    Imagine you're an animal! Shrink down to the size of a frog or newt and think about how you might get in and out of the pond. Use bricks, rocks or logs to create little stepping stones and ladders in and out of the pond!

  5. At last, you can fill your pond! Whenever possible, use rainwater. Tapwater contains too many chemicals to be good for a pond. Maybe your parents have got a water-butt to use? Or perhaps you can let it fill up naturally on a stormy day!
  6. Plant up your pond. Don't try and plant your parents' garden flowers or prize roses - they won't do very well in a pond at all! Use aquatic plants, ideally in special aquatic plant pots (which have mesh sides). Use a very low nutrient soil (you can buy special soil for ponds), mixed with grit.

    Submerged pondweed is vital to help the pond stay clear, Always use native plants in ponds  rigid hornwort and whorled water-milfoil are recommended. You can buy these from garden centres or specialist pond suppliers.

    Include native marginal plants around the edge, poking clear of the surface to give perches and cover to wildlife. Just be very careful to only use plants which won't grow too large for such a small space. Two or three plants is the maximum for a pond this size. Try plants such as water forget-me-not, lesser spearwort and marsh marigold.

  7. Aftercare. For the first few months, don’t worry if you get algae or blanket weed (which is like strings of green gloop!), it's easy to get out by winding it around a stick and great fun!

    As your mini-pond matures, all the pond creatures you’ve attracted will help keep the water clear. You may need to top the pond up in hot weather  try to use rainwater from a water butt.
  8. And now see what arrives! Don't be tempted to bring in buckets of pond life from elsewhere. Pond creatures are great at finding ponds themselves. Toads tend to like larger ponds, but there is every chance a frog or newt will find your mini-pond, especially if you provide little patches of cover next to a pond, and maybe add a frog and toad abode nearby. After a while, your pond should slowly become a home to a host of amazing pond creatures. Why not take another step towards your Wild Challenge and try pond dipping?
