The selfish ivy had taken everything out of the soil for itself. As I dug up the echinacea, verbena and thyme to replant in pots, I realised that few but the most stubborn plants would grow in this unfriendly earth. Further along the walled bed, two small trees had littered the soil with fallen leaves and not even the Japanese anemone nor the lemon balm would venture any further into the shade.

Then I had an idea. Bees, butterflies and other garden visitors need water as well as food. If I couldn’t grow any flowers for wildlife to eat, then I would give it a place to drink instead.

A quick search around the house and garden and I found everything that I needed to create two mini-wildlife ponds.

Tip: The garden is a great place to find new uses for old things. I also feel that we rely too much on recycling. The next time you think about buying garden accessories have a look around the home or second-hand shops first. A bucket with a broken handle could make a frog pond, a cracked flower pot for a toad house, chipped cups for bird feeders and old serving forks and spoons can be used as stakes for plants.

An empty plastic container and a stained washing-up bowl – both in the queue for a trip to Harefield’s recycling skip – were just the right sizes for my mini ponds. I dug a hole in the earth for each and buried the bowls up to the rims to make it easy for hedgehogs to stop by and dip in for a drink.

Next, I poured gravel into the bottom and made a pile of stone ‘steps’ for frogs, toads or newts to climb in and out. Larger stones and broken paving slabs surrounded the edges. That done, I filled up the ponds with tap water – and some dechlorinator (it hasn’t rained enough lately to collect rainwater in buckets) – and added duckweed and hornwort from the larger fish and frog ponds.

Tip: Duckweed and hornwort can quickly grow and become a nuisance. I find it easy to manage by removing a handful now and then as compost for the garden or to put into the bird bath and rain buckets. The plants seem to keep the still water clear and to deter mosquito larvae as well.

Finally, a few pieces of crockery filled with pebbles made watering holes for thirsty insects. Here are the results:

It wasn’t long before the frogs, and the snails, found the new garden ponds.

Although some still prefer our more established frog pond.

We have a lot of slugs in the garden too, but, as you might guess, we don’t use slug-and-snail pellets. Any slugs that I find on the Japanese anemone, which is their favourite thing, are put on the compost bins where they can eat to their hearts’ content.

The mini-wildlife ponds are also the perfect place for baby snails but overall life in the garden sorts itself out, and the frogs seem to keep the slug and snail population in balance.

As you might imagine, our garden is also pesticide-free and weedkiller-free. In fact, I was once told by a gardener, when asking about how to control the bamboo and bindweed last year, that the bees don’t mind Roundup. I didn’t believe him and I’m glad to say that we found another gardener willing to dig out the bamboo (an expert job because its roots were entwined around the roots of the smoke tree) rather than poison it. Meanwhile, John and I weeded out the bindweed and covered the area using garden sheeting and gravel.

We’ll never be rid of either (bindweed seeds, for example, can live in the soil for many years), but we manage both quite well by physical methods – digging, hoeing and weeding.

The old bamboo grove is now used as a bird-feeding station. Here, the birds can feast on fat balls and splash about in the bath and make as much mess as they want on the rhizome-riddled earth. The area is sheltered by the smoke tree and bushes to allow small birds to make a quick exit if the sparrowhawk flies past.

As a thank you, the birds have left us some beautiful flowers this year from other gardens, such as this love-in-a-mist. Birds are very good gardeners.

Life is always very busy in the garden.

After the bamboo was cut down, several thistles sprung up in its place. John and I kept the largest thistle next to the fence for the sweat bees. It has been a popular breakfast bar.

On the gravel patch, I planned to plant mini-wildflower meadows in pots but the garden had other ideas. This summer’s surprise is the butterfly-and-caterpillar habitat that has sprung up in the form of a toadflax meadow.

The carder bees also buzz around the purple flowers all day long – toadflax is a rewarding plant for wildlife.

While my mason bees that I ordered earlier in spring fell victim to the backwinter and an army of ants, a single local mason bee found the insect hotel when the weather warmed up again. She worked very hard for almost a month to fill as many tubes as possible with her eggs and food for her larvae.

I last saw our mason bee resting on the fence, her exhausted and bedraggled body fit to drop, and then she was gone. A fortnight later, I realised that she wasn’t coming back and that three of the tubes were only partly finished. So I completed her work by making mud plugs myself and hoped for the best for next spring.

The leafcutters moved in next and have been busy filling up the remaining tubes.

Another resident has been watching their progress with interest.

As far as I can tell, he has not caused any mischief and so has not been evicted.

The ants made up for their earlier destruction of my mason bee cocoons by allowing me to watch this year’s queens fly away to start new nests. They didn’t fly very far it seemed and probably we will have more ant nests on the lawn again.

The honeybees returned after the June gap for their annual crop of a flowering shrub around the fir tree. As a beekeeper, I have an interest in planting a garden that is pleasing to bees. This summer, the salvia and scabiosa have been the clear winners, probably because they have flourished and grown rapidly in the sun. The honeybees have also discovered the lemon balm which is in flower and a few bumble bees have opted for the more traditional choice of our lavender bush.

I’m also delighted that our myrtle tree is in flower for the first time since it was planted in the garden, although it has not yet produced enough flowers to delight the pollinators.

Of course, it’s not all about the birds and the bees. On occasion, we have human visitors too.

They provide something interesting for the fish to look at.

Life in the garden is precarious and it can all change as quickly as it came. Already the plants seem too far ahead of the season and the blackberries are beginning to ripen over the fence. I have found a new hobby in collecting my own seeds and cuttings to grow more of the plants and flowers that the wildlife in our garden loves most. Bluebell bulbs can be divided and planted under the smoke tree in autumn, seeds are being collected from the salvia and seedheads from the scabiosa to provide more forage for next year’s bees, and the toadflax and rose campion ‘alba’ are being encouraged to sprout everywhere for next year’s butterflies.

This week on BBC begins The British Garden: Life and Death on Your Lawn looking at how well British gardens support wildlife. From the frog ponds in the shady flower beds to the compost bins and piles of logs and leaves, I like to think that our garden supports a lot of wildlife and that there is still much more to discover beyond our back door.
