Make a Wildlife Pond in Your Backyard

wildlife-pond

Providing the perfect home for some of the most decorative foliage and flowering plants, a pond also mirrors the sky, reflecting light into the garden. A wildlife pond is especially beautiful, and will also attract a whole host of beneficial animals, birds, and insects. Make one with sloping sides, to allow easy access for creatures to come and go, and leafy edges that offer habitats and cover. Site your pond in an open area, not too near overhanging trees because decaying autumn leaves will muck up the water.

The 10 Steps for Making a Backyard Wildlife Pond

 

wildlife-pond-notes1. MARK OUT THE POND

wildlife-pond-step-1 Using a hose, mark out the pond with sweeping curves for a natural effect. Calculate the area of liner you will need by adding twice the total depth (D), plus 18 in (45 cm) extra, to the length (L). Then add twice the depth (D), plus 18 in (45 cm) extra, to the width (W), and multiply the two answers (see also Step 2 below): (2xD+18 in+L) x (2xD+18 in+W).

2. DIG DOWN

wildlife-pond-step-2

Dig out the whole area of the pond to a depth of 18 in (45 cm), and angle the sides so that they slope slightly. Leave a 12–18 in (30–45 cm) wide shelf around the sides at this depth. Then dig out a central area 3 ft (1 m) deep, and an adjacent area, about 30 in (75 cm) deep, creating two deeper areas to keep plants and wildlife frost-free in winter.

It is essential that the top edges of the pond are level all the way round, or water will drain out unevenly. Place a spirit level on a straight plank of wood and test the level in six or seven different places, building up or removing soil as necessary.

4. LINE THE BASE

wildlife-pond-step-4Smooth the edges, and remove large or sharp stones from the sides and base. Line the pond with old carpet or a special pond underlay. Do not use sand because it falls away from the sides and will fill up the hole.

5. LINE WITH BUTYL

Center the liner over the hole and push it down in the middle, allowing pleats to form against the sides and base. Fill the deepest part with water; the weight will pull the liner into place.

6. FILL WITH WATER

wildlife-pond-step-6Fold the liner in neat pleats over the shelf and top edges, and check that it is bedded into the bottom of the pond. Top up with more water, which will force the liner against the shelf and sides.

7. TRIM TO FIT

As you fill the pond, move around so that the liner is pulled evenly into the hole. When the pond is full, trim the liner with a sharp knife, leaving up to 18 in (45 cm) excess around the edges.

To turf up to the edges, leave 10 in (25 cm) of excess liner and butt the turves up to it. Or add stones by mortaring them onto the liner, making sure no cement falls in the water in the process.

9. PLACE THE STONESwildlife-pond-step-9

When positioning the stones, make sure that they do not overhang the edge by more than 2 in (5 cm). This will prevent them from tipping up and both you and the stones falling into the water when you walk on the edge.

Place rocks in the water but protect the liner from damage by placing them on cushions of folded plastic sacks or spare rolled-up liner. Ensure the rocks are stable, but do not mortar them in. The pond is now ready to plant. Use the shelves around the sides for marginal plants, and the deeper areas for submerged aquatics, such as water lilies.

Top Tip: Choosing Pond Plantswildlife-pond-plants

There are four main types of pond plant; deep-water aquatics, oxygenators, marginals, and bog plants. Water lilies are deep-water aquatics and sit on the bottom of the pond, although some will grow in shallow water. Check the depth required on the label (measured from the pot surface) and raise them up on bricks as required. Oxygenators are essential plants that help keep the water clear. Marginals, such as the marsh marigold, Caltha palustris (right), prefer the shallows around the edge of the pond, and will be happiest on the shelf. Site bog plants in the damp area around the pond—not in the water.

  1. Thanks for the info, I have added a bookmark.

  2. Wohh just what I was searching for, thank you for putting this up.

  3. This is a great guide. Here is a tip for new water gardens.

    They will go through a cycling period where the water will appear cloudy. You can speed up cycling by planting a large number of pond plants like floaters, submerged, marginals and waterlilies. These plants will also absorb excess nutrients which can improve water quality!
