Jobs to Do in the Garden in September – Your Essential Autumn Garden Checklist

September Garden Jobs for Eastbourne & East Sussex

September is an important month in the garden. With summer coming to an end and autumn approaching, it’s the perfect time to get your garden back under control and prepare your lawn, borders, hedges, trees and outdoor spaces for the colder months ahead.

Whether you enjoy gardening yourself or need help getting those larger jobs completed, there are plenty of September garden jobs to tackle.

At CG Garden Services, we provide professional garden maintenance and a wide range of garden services throughout Eastbourne and surrounding areas of East Sussex, including Polegate, Hailsham, Stone Cross, Pevensey and Langney Point.

Here are some of the most important jobs to consider this September.

1. Give Your Lawn Some Autumn Care

After a long summer, your lawn may be looking tired, dry or patchy. September is an excellent time to give your grass some attention before winter arrives.

Consider:

  • Cutting the grass regularly, but gradually raising the mowing height as temperatures fall.

  • Removing excessive thatch with a scarifier.

  • Aerating compacted areas of lawn.

  • Overseeding thin or bare patches.

  • Applying a suitable autumn lawn feed.

  • Removing fallen leaves before they block light from reaching the grass.

Good autumn lawn care now can help your lawn recover from summer and improve its appearance going into winter.

2. Trim Hedges and Tidy Boundaries

September can be an ideal time to bring overgrown hedges back under control.

With the main bird nesting season coming to an end, many hedge maintenance jobs can now be carried out, although it is still important to check carefully for any active nests before cutting.


Hedge trimming can improve the appearance of your property, keep paths and driveways clear and prevent hedges from becoming excessively large.

For particularly overgrown hedges, a heavy hedge reduction may be required rather than a simple trim.


CG Garden Services can help with hedge trimming, hedge reductions and general garden maintenance in Eastbourne and surrounding areas.

3. Clear Fallen Leaves and Garden Debris

As September progresses, leaves will begin to fall from trees and shrubs.

Regularly clearing leaves from lawns, patios, paths and borders helps keep your garden looking tidy and can reduce the risk of slippery surfaces.


Rather than simply throwing everything away, consider using suitable leaves and garden waste for composting where possible.


If you have a large amount of garden waste following a clearance, pruning or hedge reduction, CG Garden Services can also help with garden waste removal and chipping services.

4. Prune and Cut Back Summer Growth

Many plants will have produced plenty of growth during the summer months.


September is a good opportunity to tidy back plants that have become overgrown and remove dead, damaged or diseased material where appropriate.


However, avoid cutting plants indiscriminately. Some shrubs benefit from pruning at different times of the year, so it is important to know what you are cutting and when it should be pruned.

5. Start Preparing Your Garden for Autumn

Now is the time to start thinking about the wetter and colder months ahead.

Check:

  • Fences for loose or damaged panels.

  • Gates for sticking, sagging or damaged hinges.

  • Paths and patios for moss, algae and dirt.

  • Drainage around lawns and borders.

  • Outdoor structures for signs of damage.

  • Trees and shrubs for dead or damaged branches.


Getting small problems dealt with now can prevent them becoming bigger and more expensive problems during the winter.

6. Clean and Maintain Patios and Driveways

Summer often leaves patios and driveways covered in dirt, algae, moss and general grime.


Jet washing patios and driveways can make a dramatic difference to the appearance of your outdoor space and is a great way to freshen up your garden before autumn.


If your patio or driveway has become slippery or heavily soiled, professional pressure washing can help restore its appearance.

7. Plant Spring Bulbs

September is a great time to start planning for next spring.

Many spring-flowering bulbs can be planted during autumn, including:

  • Daffodils

  • Crocuses

  • Tulips

  • Alliums

  • Snowdrops


Planting bulbs now gives them time to establish before winter and provides welcome colour when spring arrives.

8. Divide Overcrowded Perennials

If your perennial plants have become large or overcrowded, September can be a good time to divide suitable plants.


Dividing established perennials can help rejuvenate them, create additional plants for other areas of the garden and prevent borders from becoming overcrowded.

9. Tidy Garden Borders

Summer growth can quickly make borders look untidy.


September is a good month to remove spent annuals, cut back suitable herbaceous plants, remove weeds and add compost or well-rotted organic matter where appropriate.


A good autumn tidy-up can make your garden much easier to manage over the winter.

10. Consider a General Garden Clearance

If your garden has become overgrown during the summer, September is an ideal time to get it back under control.


A garden clearance in Eastbourne can include cutting back overgrown vegetation, clearing weeds, removing unwanted growth, tidying borders and clearing garden waste.


Getting the garden under control before autumn and winter can make next year’s maintenance considerably easier.
