The Kent Gardener – September 2026
Why September Is the Gardener’s New Year
Most people think January is the time for fresh starts. Gardeners know better.
For me, September has always felt like the beginning of a new year. The frantic rush of spring has passed, summer has shown us what the garden is capable of, and now we have the opportunity to make thoughtful improvements while the conditions are still on our side.
The soil is warm from months of sunshine, nights are becoming cooler, and the first autumn rain often does much of the hard work for us. It’s an ideal combination for planting trees, shrubs and hardy perennials.
This is also the month when I encourage people to stop looking only at what’s flowering and start looking at the bones of the garden. As leaves begin to thin over the coming weeks, the structure becomes more obvious. Paths, patios, borders, fencing and the way different areas connect all come into sharper focus.
A well-designed garden should look good in every season, not just during those few glorious weeks in June.
Some of our most rewarding projects begin with a simple conversation in September. Clients have enjoyed their gardens throughout the summer and have a clear picture of what works and what doesn’t. Perhaps they need a larger patio for family gatherings, better lighting for autumn evenings, or planting that offers colour long after summer flowers have faded.
The beauty of September is that there’s still plenty of time to make those improvements before winter arrives.
Every garden tells you what it needs. September is simply the month when it’s easiest to listen.
In Our Gardens
As summer draws to a close, our maintenance teams are beginning the gentle transition into autumn. Hedges are receiving their final trims of the season, lawns are recovering from the heat of summer, and borders are being tidied without losing the seed heads and late flowers that provide interest for both people and wildlife.
We’re also busy preparing for our autumn landscaping programme. New patios, fencing, planting schemes and complete garden renovations are all easier to establish at this time of year, giving gardens every opportunity to settle before next spring.
One thing we always remind clients is that autumn isn’t the end of gardening. In many ways, it’s when some of the best work begins.
Weather Watch
September weather in Kent can change quickly. Warm afternoons can be followed by cool, damp mornings, making it an excellent month for new planting.
Keep an eye on fallen leaves as they begin to appear, especially on lawns. Removing them regularly allows light and air to reach the grass and helps prevent disease developing later in the season.
Continue watering anything planted this year if conditions remain dry, but reduce the frequency as temperatures begin to fall.
A Message to Other Estate Owners

Matt’s Garden Tip
September is the perfect month to renovate a tired lawn.
Scarifying, aerating and overseeding now gives new grass the best chance to establish while the soil is still warm. A little work this month often makes an enormous difference by next spring.
Plant Spotlight
Japanese Maple (Acer palmatum)
Few trees announce the arrival of autumn quite as beautifully as a Japanese maple.
Their foliage gradually changes through rich shades of gold, orange and crimson, bringing colour just as many summer plants begin to fade. They’re equally at home in a small courtyard garden or as a focal point in a larger border.
Choose a sheltered position away from strong winds, and you’ll enjoy decades of spectacular autumn colour.

Ask Matt
“Is autumn really a good time to plant trees?”
Absolutely.
In fact, it’s one of the best times of year. The warm soil encourages root growth while cooler air reduces stress on the plant. Trees planted in autumn often establish far better than those planted during the heat of spring or summer.
The key is to water them well after planting and keep an eye on them through their first year.
Matt’s Thought for the Month
A garden is never really finished.
Every season offers another opportunity to improve it, simplify it or simply appreciate it a little more than you did the year before.
See you in the garden next month.
