Your Garden in September: Preparing Your Garden for Autumn

September is a month of change in the garden. Summer may still be hanging on, but the days are getting shorter, temperatures are beginning to drop, and the first signs of autumn are starting to appear.
It’s also one of the busiest and most useful months for gardeners. There are still flowers to enjoy, vegetables to harvest and lawns to maintain, but September is also the perfect time to start preparing your garden for the months ahead.
A little work now can make a big difference when autumn and winter arrive.
With cooler temperatures and more regular rainfall, lawns often begin growing more vigorously again after the slower growth of summer.
September is a good time to give your lawn some attention. Continue mowing regularly, but avoid cutting the grass too short. If your lawn has become compacted over the summer, aerating it can help water, air and nutrients reach the roots more effectively.
You can also repair bare or damaged patches with grass seed while conditions are still favourable for germination.
As summer flowers begin to fade, September is a good time to remove dead or dying plants and clear away any unwanted growth.
However, don't feel that everything needs to be cut back immediately. Some seed heads provide valuable food for birds and can also add structure and interest to the garden throughout autumn and winter.
Leaving some plants standing until later in the year can also provide shelter for insects and other wildlife.
One of the most rewarding September jobs is planning ahead for next spring.
Early autumn is an excellent time to plant spring-flowering bulbs such as daffodils, crocuses and alliums. Getting them into the ground now gives them time to establish their roots before winter.
If you're planning new borders or want to add more colour to your garden next year, September is also a good opportunity to start thinking about what you'd like to plant.
There's still plenty to harvest in September, including runner beans, courgettes, tomatoes, carrots and many other summer crops.
Continue picking regularly to encourage plants to produce as much as possible. You can also begin clearing crops that have finished and preparing the soil for the months ahead.
If you're growing pumpkins or squashes, keep an eye on them as they mature. With autumn approaching, protecting ripening fruit from damp ground can help prevent them from rotting.
September is a good month to assess trees, shrubs and hedges after the growing season.
Remove any dead, damaged or diseased branches where appropriate, and take a look at hedges to see whether they need attention before winter.
If you are planning more substantial tree work, it's always best to seek professional advice rather than attempting potentially dangerous work yourself.
Containers can continue looking fantastic well into September, but summer bedding plants will eventually begin to fade.
Remove plants that have finished and consider replacing them with autumn and winter-interest plants. Cyclamen, heathers and pansies can all add colour when much of the summer display has disappeared.
It's also worth checking pots and containers for cracks or damage before colder weather arrives.
The first leaves may already be beginning to fall, and keeping paths, lawns and patios clear becomes increasingly important as autumn progresses.
Regularly sweeping up leaves helps prevent slippery surfaces and stops thick layers of leaves from smothering grass.
Rather than simply throwing all your leaves away, consider creating leaf mould. It's an excellent natural soil conditioner and gives fallen leaves another useful purpose in the garden.
September can be a surprisingly beautiful month in the garden. Summer flowers may still be blooming, while early autumn colours begin to appear and the garden takes on a slightly different character.
Before the darker months arrive, take some time to enjoy the work you've put into your garden over the summer.
And if there are jobs you've been putting off, September is a great time to tackle them before the weather becomes colder and wetter.
