Autumn can be an easy season to underestimate.
Summer has been busy, harvests are still coming in and there always seems to be another job that needs doing.
Then suddenly September arrives and you're wondering what happened to all those plans for autumn crops.
A productive autumn market garden starts with planning before summer is over.
Look at What Is Already Growing
Start by looking at your existing beds.
Which crops are going to finish soon?
Which will continue producing into autumn?
Which beds will become available?
Make a simple list.
You don't need a complicated farm management system.
Even a basic bed map can help you see where gaps are likely to appear.
Work Backwards From Harvest
One of the easiest ways to plan autumn crops is to start with the harvest date.
Ask:
What do I want to harvest in October?
Then work backwards.
How long does the crop take to mature?
When does it need to be sown?
Does it need to be transplanted?
Will it need protection?
What happens if temperatures fall earlier than expected?
This approach is much more useful than simply asking, "What can I sow now?"
Don't Forget the Shorter Days
Autumn growing is very different from summer growing.
As daylight decreases, crop growth slows.
A crop that grows quickly in July may take significantly longer later in the year.
This is why autumn sowings need careful timing.
It is also why varieties matter.
Look for crops and varieties suited to cooler conditions and shorter days where appropriate.
Use Your Protected Space Wisely
If you have a polytunnel, greenhouse or low tunnels, think carefully about what you want them to do.
Protected space is limited.
Using it for crops that could happily grow outside may not always be the best use of that valuable growing area.
Instead, consider crops that genuinely benefit from protection.
This might include:
-
Salad leaves
-
Spinach
-
Herbs
-
Asian greens
-
Young plants
-
Crops being pushed later into the season
Think about your customers too.
A relatively small area of high-value or frequently harvested crops may be more useful than filling the entire tunnel with one crop.
Plan Your Bed Gaps
As summer crops finish, you will inevitably have beds becoming available at different times.
Some may be ready in August.
Others may not be available until September or October.
Rather than treating every bed the same, make a simple plan for each one.
For example:
Bed 1: Summer crop → winter salad
Bed 2: Summer crop → cover crop
Bed 3: Summer crop → overwintering brassica
Bed 4: Summer crop → mulch until spring
This makes the autumn workload much more predictable.
Think About Soil Protection
As rainfall increases, protecting the soil becomes increasingly important.
Try to avoid leaving large areas of soil bare for long periods without a reason.
Depending on your system, this could mean:
-
Growing another crop
-
Using a cover crop
-
Applying mulch
-
Keeping established crops in place
-
Minimising unnecessary soil disturbance
The goal is to finish autumn with soil that is still in good condition.
Keep an Eye on Weeds
Autumn weeds are easy to ignore.
They're often slower than their summer counterparts and it can feel like the problem is disappearing.
But allowing weeds to establish before winter can create extra work later.
Regular light cultivation when conditions allow is generally easier than dealing with a heavily overgrown bed.
The same principle applies to paths and around infrastructure.
A little maintenance now can save time in spring.
Prepare for the Weather
Autumn weather in the UK can be unpredictable.
One week can feel like summer.
The next can bring heavy rain and cold winds.
Have your crop protection materials ready before you need them.
Check:
-
Fleece
-
Hoops
-
Low tunnels
-
Netting
-
Polytunnel covers
-
Irrigation
-
Drainage
-
Harvest equipment
You don't want to discover that something needs repairing when the weather has already changed.
Review the Season While You Still Remember It
Autumn is also a good time to look back at the growing season.
Which crops sold well?
Which varieties performed?
Which crops were difficult to harvest?
Where did you lose time?
Which beds worked particularly well?
What would you do differently next year?
Write it down.
It is surprisingly easy to forget the details once winter arrives.
Those notes can become incredibly useful when you start planning the following season.
Autumn Doesn't Have to Be an Afterthought
A productive autumn market garden isn't created by trying to squeeze another summer into the calendar.
It's about working with the season.
Choose suitable crops.
Plan your sowings.
Use protected space carefully.
Keep soil covered.
Prepare for changing weather.
And make sure your tools and infrastructure are ready.
The more of this you can organise before summer ends, the easier autumn becomes.
And when the days start getting shorter, you'll be glad you did.
