Creating a garden pond
A butyl liner allows you to make an attractive shape
1 Define the perimeter and shape of the pond with string or a hosepipe and start to dig it out. Move the soil and turf out of the way.
2 Dig out your pond in graded shelves (this is important so wildlife can climb out) and make sure each shelf is level using a spirit level.
3 Line the pond with a thick layer of sand or old carpet. This stops sharp stones or roots from puncturing the lining.
4 Get someone to help you drape the lining over the hole. Spread it carefully without dragging it and anchor the sides with bricks.
5 While the pond is filling with water, trim the sides of the lining so there is a 12in (30cm) overlap. Anchor it with cemented edging stones or turf.
6 Plant up lilies in baskets lined with hessian and filled with aquatic compost. Any marginals can be planted straight into mud at the sides.
7 Place your plants where they will thrive. Stand some on bricks and don’t forget to add oxygenators to help keep the water clear.
8 The water will soon clear as any sediment sinks to the bottom. If you want to add fish, wait for six weeks until the plants have become established.
