September can feel like the point when the allotment year is winding down, but there is still plenty to do. In fact, September allotment jobs can be some of the most important of the entire gardening year. Summer crops are beginning to finish, the first cooler and wetter days are arriving, and the plot needs to make the transition from productive summer garden to a space that can cope with autumn and winter.
For new growers, this can be a particularly useful time of year. The excitement of spring sowing has passed, the abundance of summer has started to settle, and you can finally see which crops performed well and which ones were more trouble than they were worth. Rather than simply clearing everything away and waiting for spring, September is an opportunity to make sensible decisions about what happens next.
Whether you have taken on a new allotment garden, or have been growing for years, autumn allotment preparation can make the colder months considerably easier. Clearing finished crops, tackling persistent weeds, improving the soil and making use of empty beds now means there is less work waiting for you when spring arrives.
What Should You Do On An Allotment In September?
The list of September allotment jobs will vary depending on what you have grown, but this is a month when regular maintenance really pays off.
Summer crops such as courgettes, runner beans and tomatoes may still be producing, so don’t clear healthy plants simply because September has arrived. Continue harvesting while crops remain productive, but start thinking about what will replace them once they finish.
At the same time, keep an eye on weeds. September can be an excellent opportunity to tackle areas that became overgrown during the summer, particularly around paths, sheds and the edges of beds.
September Allotment Jobs To Prioritise
- Harvest remaining summer crops regularly.
- Clear crops that have completely finished producing.
- Remove weeds before they establish further.
- Check plants for signs of disease before adding anything to compost.
- Clear and tidy paths and access areas.
- Improve empty beds with suitable organic matter.
- Consider covering bare soil where appropriate.
- Sow or plant suitable autumn and overwintering crops.
- Check tools, supports and garden equipment before wetter weather arrives.
- Make notes about successes and failures from the growing season.
You don’t have to transform the whole plot in one weekend. A little work each time you visit can make the difference between a manageable autumn allotment and a daunting spring clear-up.
What Can You Plant On An Allotment In September?
September is certainly not the end of the growing season. There are still opportunities for September sowing and planting, particularly if you want to grow crops that can provide autumn, winter or early spring harvests.
Depending on your location and growing conditions, you may be able to sow crops such as winter salads, spinach, spring onions, radishes and other suitable hardy varieties. Garlic and certain overwintering crops can also become part of your plans as the season progresses.
The important thing is to check the growing requirements of individual crops rather than assuming that everything has to wait until spring.
Make Use Of Empty Allotment Beds
One of the easiest mistakes to make is to clear a summer crop and then leave the bed completely empty for six months.
If you have suitable conditions, consider whether the space can be used for an autumn or overwintering crop. Alternatively, you could improve the soil and cover the bed to protect it through the winter.
This is where good allotment planning becomes valuable. A productive plot does not have to look exactly the same throughout the year. Beds can have several purposes depending on the season.
Preparing Your Allotment For Autumn And Winter
As the days become shorter, preparing an allotment for winter should start moving higher up your list.
Clear away plants that have finished, but don’t feel that everything needs to be stripped back immediately. Some plants can continue providing food well into autumn, while other vegetation may provide useful shelter for wildlife.
Pay particular attention to anything diseased. Healthy plant material can often be composted, but diseased material may need to be disposed of appropriately to avoid spreading problems around the plot.
Autumn is also a good time to look at the structure of your allotment. Are paths easy to walk along when wet? Are tools stored securely? Are canes and supports likely to survive strong winds? Small jobs completed now can prevent bigger problems later.
September Is The Time To Learn From Your Growing Season
One of the biggest benefits of an allotment is that every season teaches you something.
By September, you have plenty of evidence to work with. You know which crops produced well, which needed constant attention and which simply weren’t worth the space they occupied.
Ask yourself:
- Which vegetables would you definitely grow again?
- Which crops produced more than you could realistically use?
- Which areas of the plot dried out too quickly?
- Where did weeds become a problem?
- Which plants suffered from pests or disease?
- Did you have enough time to maintain everything you planted?
- What would you do differently next year?
Keeping a simple allotment gardening diary can be surprisingly useful. A few notes now can save you from trying to remember what happened when you return to planning next year’s crops.
Don’t Wait Until Spring To Improve Your Allotment
There is a tendency to think of spring as the time when allotment gardening really starts again. However, some of the best preparation can happen during autumn.
As beds become available, consider how you want to manage them over winter. Improving the soil, adding suitable organic matter and keeping weeds under control can all contribute to a healthier and more manageable plot.
This is also the perfect time to think about crop rotation and where different vegetable families will be planted next year. Rather than making decisions when you’re under pressure to start sowing, you can take a more considered approach while the growing season is still fresh in your mind.
