When Is The Best Time To Build A Wildlife Pond?

A wildlife pond can be built at most times of year. Building in autumn or winter gives it time to settle before spring, when frogs and newts start to breed, but a pond built in spring or summer will still be found by wildlife quickly.

Will A Wildlife Pond Attract Mosquitoes?

A balanced wildlife pond is rarely a problem. Dragonfly larvae, water beetles and other insects eat mosquito larvae, and frogs and newts help to keep numbers down.

How Big Does A Wildlife Pond Need To Be?

Even a small pond will attract wildlife. Larger ponds hold steadier water temperatures and support more species, but the most important things are shallow edges, planting and clean water.

Do You Use Native Plants?

We use a mix of plants chosen for wildlife and for the conditions in your garden, including native species, and we avoid invasive plants that can spread into the wider countryside.

What If Great Crested Newts Use My Pond?

Great crested newts are protected by law. They are welcome in a new pond, but if you think they already live in a pond that needs work, tell us before anything starts, because work that affects them may need a licence and has to be timed carefully.

Water For Wildlife

A Pond That Fills With Life.

A wildlife pond is one of the best things you can add to a garden. Within a season it can bring in frogs, toads, newts, dragonflies, damselflies and birds that come to drink and bathe. It needs very little looking after once it has settled, and it changes through the year in a way that a lawn or a border never does.

We design and install wildlife ponds of every size, from small ponds beside a patio to large natural ponds in the middle of a garden. Each one is built around the same simple ideas: gentle edges, plenty of planting and clean water.

Wildlife Ponds

What We Offer.

Every part of the job is handled by the same team, so the whole space is finished to one standard.

01
Gently Sloping Edges
At least one shallow, sloping side or cobble beach, so animals can get in and out of the water safely.
02
Planting Shelves
Shallow shelves around the edge for marginal plants, which give cover to wildlife and help keep the water clear.
03
Deeper Water
A deeper area in the middle, which stays cooler in summer and gives wildlife somewhere to shelter in winter.
04
Native Planting
A mix of marginal, floating and oxygenating plants, including native species, chosen for wildlife and for your garden.
05
Rainwater Where Possible
Advice on filling and topping up, ideally with rainwater, which carries fewer of the nutrients that feed algae.
06
Simple Aftercare
A short guide to the few jobs worth doing each year, and seasonal care if you would like us to look after it.

Built For Wildlife From The Edges In

Most of the life in a pond happens at the edges. Shallow water warms quickly in spring, which suits frogspawn and tadpoles, and marginal plants give young newts and insects somewhere to hide. That is why our wildlife ponds have wide, shallow shelves and at least one gently sloping side or cobble beach.

The slope matters for another reason too. Hedgehogs, birds and other animals that come to drink can struggle to get out of a pond with steep sides. A shallow beach lets them climb out again, and it gives birds a safe place to bathe.

Through The Seasons

A Year At A Wildlife Pond.

Choose a season to see what is happening in and around the water, and the few jobs worth doing.

Spring

Frogs and toads return to breed, and frogspawn appears in the warm, shallow water at the edges. Newts follow soon after.

Worth Doing

Very little. Leave the margins undisturbed and let the planting grow back.

Summer

Dragonflies and damselflies emerge, birds come to drink and bathe on the cobble beach, and the planting is at its fullest.

Worth Doing

Top up in dry spells, ideally with rainwater from a water butt.

Autumn

Leaves fall and the planting begins to die back. Breeding has finished, so this is the time for any bigger jobs.

Worth Doing

Clear fallen leaves before they sink and rot.

Winter

The deeper water stays a little warmer than the shallows, and much of the pond's life rests out of sight.

Worth Doing

If it freezes, never break the ice by force; stand a pan of hot water on it instead. Cut the marginal plants back in late winter.

A general guide. Timings shift a little from year to year with the weather.

Plants Instead Of Pumps And Chemicals

A wildlife pond does not need a filter or chemical treatments. The planting does the work. Oxygenating plants under the water, water lilies and other floating plants on the surface, and marginal plants around the edges use up nutrients, shade the water and keep algae under control.

We choose plants to suit your pond and its position, with a mix of native species that support wildlife. The pond looks new for the first few weeks, but the planting fills in quickly, and within a season it starts to look as though it has always been part of the garden.

Why Wildlife Ponds Are Best Without Fish

Fish and wildlife ponds do not mix well. Fish eat frogspawn, tadpoles and the larvae of insects such as dragonflies, and they add nutrients to the water. If you would like fish as well, we can build a separate ornamental pond for them, or talk you through a koi pond, which is designed for fish from the start.

Wildlife arrives on its own. Frogs, newts and insects find a new pond quickly, so there is no need to bring in spawn or animals from other ponds, which can spread disease and invasive plants.

Our Wildlife Pond At Woodhurst

In September 2026 we finished a wildlife pond at Woodhurst, a village just north of St Ives. The brief was a pond that looked as though it had always been in the garden. We built shallow shelves on three sides and a cobble beach on the fourth, and planted the margins while the water was still settling. Within weeks the planting was already looking established.

You can see more of this pond and our other recent projects on our work page, or read about how we design ponds for each garden.
