CREATING A WILDLIFE POND

Brief: Create a small wildlife pond in an existing border to attract natural predators to control pests such as slugs and snails.

Solution: Much of the planting and in particular the large Cotinus coggygria had to be removed. It is important to remove any roots, stones and debris that may penetrate the pond liner.

Having cleared a suitable area, I dug a two-tiered hole incorporating a shallow ledge to allow for a variety of plants. One end has a gentler incline to allow easy access for animals.

Sand was used to sculpt the shape. A textile underlay was laid first for added security against leaks then a butyl liner was laid on top. It is important to get the levels correct. This particular pond was dug into a gentle slope. The permanent water level should be at least 15cm below the top of the liner to prevent water loss.

I filled the pond with water from the mains and introduced some micro-organisms from the river at the end of the garden. It's a good idea if you can, as it gives everything a bit of a kick-start.

Result: A small wildlife pond that will attract many animals beneficial to the garden. Also the way the light plays across water can act as a wonderful focal point in any garden.
