September 2026 - Ponds, Long Grass & Letting Nature In
September is a lovely month in the garden. The rush of summer begins to ease, but there is still plenty happening — seeds ripening, insects taking advantage of the last warmth, birds searching through fading vegetation and plants gradually beginning to retreat towards autumn.
It is also a good time to step back and think about what makes a garden genuinely useful to wildlife.
This month we've been working on a number of gardens with wildlife and biodiversity in mind, and a few simple things keep coming up: water, longer vegetation, leaving things a little untidy, and making good use of what the garden already produces.
Ponds: one of the best things you can add
If you want to make a garden more valuable to wildlife, a pond is hard to beat.
It doesn't need to be enormous. Even a relatively small pond can provide drinking water, bathing opportunities and habitat for an enormous range of creatures.
Frogs, newts, dragonflies and other aquatic invertebrates can all benefit, while birds, bees and other insects use the edges for drinking.
And a pond doesn't have to look like a formal ornamental feature. A simple, naturalistic pond surrounded by planting can become one of the most interesting parts of a garden.
The important thing is to think about the pond as an ecosystem rather than an object — shallow areas, vegetation, shelter and easy access for wildlife all matter.
Don't be too tidy
One of the simplest things we can do for wildlife costs absolutely nothing:
Leave things alone.
There is an understandable temptation to cut everything back as soon as plants start looking past their best. But what looks untidy to us can be incredibly valuable to wildlife.
Long grass provides shelter and habitat. Seedheads provide food for birds. Hollow stems and dead vegetation can provide places for insects to overwinter. Fallen leaves and plant debris become habitat and eventually return their nutrients to the soil.
That doesn't mean letting every garden become completely wild. There is a balance.
Paths, entrances and areas that need to be used can still be kept neat, while other areas are allowed to grow and change naturally.
I often think of it as being selective about what we tidy, rather than trying to tidy everything.
A garden can still look cared for without every square metre being cut, clipped and cleared.
Autumn doesn't mean everything needs cutting back
September and October are particularly tempting months for the big garden clear-up.
But before reaching for the strimmer or secateurs, it is worth asking: does this actually need cutting back yet?
Where practical, leaving some plants standing through autumn and winter gives wildlife somewhere to shelter and feed. Many seedheads also provide valuable winter food for birds, while their stems and structures add interest to the garden when everything else has died back.
Often the best approach is simply to leave things until late winter or early spring, then cut them back when there is less risk of disturbing overwintering wildlife.
And when you do clear something, the material doesn't necessarily need to leave the garden.
Make your own compost
A wildlife-friendly garden is also about looking after the soil.
Composting is one of the simplest ways of keeping nutrients and organic matter within the garden rather than constantly bringing them in from somewhere else.
Grass cuttings, leaves, weeds, prunings and other garden material can all become valuable compost with a little time.
Good homemade compost can then be returned to beds and borders, improving soil structure and feeding the next generation of plants.
It is a simple cycle:
plants grow → plants are cut or die back → material is composted → compost feeds the soil → new plants grow.
There is something satisfying about keeping that cycle happening within the garden.
A garden doesn't have to be perfect to be good
Perhaps the biggest lesson from working in wildlife-friendly gardens is that sometimes doing less is actually doing more.
A pond instead of another perfectly level lawn.
A patch of long grass instead of another weekly mow.
Seedheads left standing rather than everything being cut down in October.
Leaves and plant material composted rather than taken away.
None of these things require expensive equipment or complicated wildlife schemes. They simply require us to think slightly differently about what a garden is for.
A garden can be beautiful, productive and enjoyable for people while also providing food, shelter, water and habitat for everything else that shares it.
And sometimes, the most wildlife-friendly thing we can do is simply leave a little more of it alone.
September's gardens have been a good reminder that a healthy garden isn't necessarily the tidiest one.
