Growing Broad Beans Through Winter – Complete UK Guide

Growing broad beans through winter is a fantastic way to keep your UK allotment productive during the colder months and give yourself the chance of an earlier harvest the following year. But how do you protect your broad bean plants from frost, waterlogging, strong winds and winter diseases?

If you’ve planted broad beans during October or November, you might be wondering what happens next.

Will they continue growing in December?

Should you protect the plants with horticultural fleece?

Can they survive snow?

Do broad beans need watering or feeding during January?

And what should you do if their leaves start turning yellow or developing brown spots?

These are all important questions, particularly if this is your first attempt at overwintering broad beans.

Here at Gardening with Ben, I love keeping my allotment productive throughout the year.

There’s something lovely about visiting your plot on a cold winter morning and seeing vegetables growing while much of the garden is resting.

Broad beans are particularly useful because certain hardy varieties can be planted in autumn, survive the colder months and produce an early crop of delicious beans.

One variety worth considering is Aquadulce Claudia.

This variety is well known for autumn sowing and is recommended by the Royal Horticultural Society for overwintering in suitable conditions.

However, growing broad beans through winter is different from sowing them during spring.

Cold weather slows growth.

Prolonged rainfall can leave the soil saturated.

Strong winds may damage the stems.

And damp, crowded conditions can encourage chocolate spot, a fungal disease that commonly affects overwintered broad bean plants.

The good news is that these problems can often be reduced by sensible preparation and regular checks.

You don’t need to water your broad beans every week.

You don’t need to feed them constantly.

And you don’t necessarily need to keep them covered throughout the entire winter.

What matters most is choosing the right variety, maintaining good drainage and protecting the plants when genuinely necessary.

In this complete UK guide, I’ll explain how to look after broad beans from November through to March.

We’ll cover frost, snow, wind, drainage, watering, feeding, chocolate spot, winter-growing in raised beds and pots, and how to encourage healthy flowering and pod development during spring.

So let’s find out how to keep those broad beans growing through winter!

Can Broad Beans Survive Winter in the UK?

Yes.

Suitable hardy broad bean varieties can survive normal UK winter conditions.

The Royal Horticultural Society recommends ‘Aquadulce Claudia’ for autumn sowing and overwintering.

However, success depends on the growing location and the weather.

Can Broad Beans Survive Frost?

Established hardy plants can usually tolerate ordinary winter frosts.

However, severe or prolonged freezing may still cause damage.

Will Broad Beans Survive Snow?

They may survive periods of snow, but heavy snow, strong winds and prolonged freezing can damage foliage and stems.

Do Broad Beans Grow All Winter?

Not at the same rate.

Growth slows considerably during colder conditions.

Will They Produce Beans in January?

Not normally.

The aim of autumn sowing is to establish plants for flowering and cropping later.

Are All Broad Bean Varieties Hardy?

No.

Some varieties are intended primarily for spring sowing.

Are Broad Beans Suitable for Every UK Allotment?

Not necessarily.

If your soil remains saturated throughout winter, spring sowing may be more successful.

What’s My Recommendation?

Use a hardy variety and choose your best-draining, most sheltered growing area.

Why Grow Broad Beans Through Winter?

There are several good reasons to grow broad beans during autumn and winter.

Earlier Harvesting

Successful autumn-sown plants may crop during May or June.

Productive Winter Beds

You can make use of space that might otherwise remain empty.

Early Spring Growth

Established plants can begin growing strongly as temperatures improve.

Spreading Your Vegetable Sowing

Autumn planting reduces the amount of sowing you need to do during spring.

Growing Different Crops Throughout the Year

Broad beans fit well alongside other suitable autumn vegetables.

Can Overwintering Give Bigger Crops?

Not always.

The RHS points out that quick-maturing varieties started in pots during February may harvest almost as early as autumn crops in difficult growing locations.

Is It Worth the Risk?

If your soil drains well, it’s definitely worth experimenting.

If the site is exposed or extremely wet, you may get better results from spring sowing.

Best Broad Bean Varieties for Overwintering

Choosing the right variety is essential.

Aquadulce Claudia

‘Aquadulce Claudia’ is one of the most widely recommended varieties for autumn sowing.

It produces relatively tall plants with long pods.

It’s useful for gardeners who want to establish a crop before winter.

Other Aquadulce Varieties

Some other Aquadulce types are also sold for autumn planting.

Check the seed packet carefully.

What About The Sutton?

‘The Sutton’ is a compact variety that can be useful in containers and windy sites.

It can be grown in suitable protected systems, but always follow the supplier’s sowing recommendations.

What About Witkiem Manita?

This is primarily a spring-sowing variety.

Does Every Variety Need Winter Cold?

No.

Broad beans don’t need a period of cold weather to trigger flowering.

Can You Sow Aquadulce Claudia in March?

Yes.

It’s also suitable for spring sowing.

What’s the Best Choice?

For a straightforward autumn-sown crop, I’d choose ‘Aquadulce Claudia’.

When Should You Plant Broad Beans for Winter?

The usual autumn sowing period is October and November.

October Sowing

October gives suitable hardy varieties an opportunity to establish before the coldest weather arrives.

November Sowing

November can also work, especially in mild areas with well-drained soil.

What If You Live in Northern England?

Choose a sheltered position and avoid saturated soil.

What If You Miss November?

Don’t feel you have to sow into unsuitable December soil.

You can start seeds under cover during February instead.

Can You Sow in January?

Protected sowing is possible under appropriate conditions, but this isn’t the normal outdoor sowing season.

What’s the Easiest Spring Alternative?

Sow in February under cover or directly outside during March and April.

Should You Sow More Than One Batch?

Yes.

An autumn crop followed by a spring crop can spread the harvest and reduce risk.

How to Prepare Broad Beans for Winter

Good winter care begins before the cold weather arrives.

Step 1: Choose a Suitable Bed

Look for a sunny, sheltered, well-drained position.

Step 2: Check Soil Drainage

Avoid areas where rainwater regularly collects.

Step 3: Remove Weeds

Clear perennial weeds before sowing.

Step 4: Improve Soil Structure

Add mature compost or well-rotted organic matter where needed.

Step 5: Avoid Fresh Manure

Use properly decomposed material.

Step 6: Choose Hardy Seeds

Check that the variety is intended for autumn planting.

Step 7: Sow Correctly

Plant seeds approximately 5–7.5 cm deep outdoors.

Step 8: Allow Enough Space

Broad beans need airflow around their foliage.

Step 9: Label the Row

Record the variety and sowing date.

Step 10: Consider Supports

Tall varieties will eventually need stakes and string.

Step 11: Prepare Fleece or Cloches

Keep suitable temporary protection available for severe weather.

Step 12: Check the Plants Regularly

A quick inspection after heavy rain or strong wind can prevent avoidable damage.

Gardening with Ben tip: Winter preparation doesn’t have to be complicated. The main things I’d concentrate on are strong plants, good drainage, adequate spacing and support where needed.

What Do Broad Beans Look Like in November?

If you’ve sown during October, you may begin seeing young plants emerging during November.

What Do Young Broad Beans Look Like?

They produce thick stems with paired grey-green leaves.

Should They Be Tall?

Not necessarily.

Plant size depends on sowing date and temperatures.

What If They Haven’t Germinated?

Cold conditions can delay emergence.

Could Mice Be Responsible?

Yes.

Mice sometimes eat broad bean seeds before they germinate.

Could the Seeds Have Rotted?

Yes, particularly if the soil has been waterlogged.

Should You Dig Up Every Seed?

No.

If there’s a genuine concern, carefully inspect one planting position.

Should You Feed November Seedlings?

Not routinely.

Healthy soil usually provides sufficient nutrients for early development.

What Do Broad Beans Look Like in December?

By December, autumn-sown broad beans may have several sets of leaves.

However, their growth often slows considerably.

Is Slow Growth Normal?

Yes.

Cooler temperatures and reduced daylight limit development.

Should the Leaves Stay Green?

Most healthy foliage should remain green or grey-green, although older leaves may suffer weather damage.

Can Frost Make Leaves Wilt?

Yes.

Foliage may temporarily look limp during freezing conditions.

Should You Water Wilting Plants?

Not before checking the soil.

Frozen or waterlogged roots may be unable to take up water properly.

Should You Put Fleece Over the Plants?

It may help during severe cold or exposure.

Do You Need to Feed in December?

No routine winter feeding is necessary.

What’s the Most Important December Job?

Checking drainage and ensuring plants haven’t been damaged by the weather.

Looking After Broad Beans in January

January is often one of the coldest months on a British allotment.

Your broad beans may appear to be making very little progress.

That’s usually normal.

Will Broad Beans Grow in January?

Some growth may occur during mild periods.

However, visible development is often limited.

Should You Remove Damaged Leaves?

Only where necessary.

Avoid stripping away healthy foliage.

Should You Water?

Outdoor plants normally don’t need additional water during typical winter conditions.

Should You Feed?

Not simply because the plants aren’t growing quickly.

What About Wind Damage?

Check whether stems are leaning or broken.

Can You Add Supports?

Yes, if needed.

Should Fleece Remain On Permanently?

Not automatically.

Remove or ventilate temporary protection when conditions allow.

What If Some Plants Die?

Record the likely cause.

You can still start replacement broad beans under cover during February.

Looking After Broad Beans in February

February is an important transition month.

Winter may not be over, but some plants begin responding to longer days and milder conditions.

Should Broad Beans Start Growing Again?

They may, depending on temperatures.

Is February a Good Time to Inspect Leaves?

Yes.

Look for unusual spots, yellowing or damaged stems.

Can Chocolate Spot Appear?

Yes.

The RHS identifies late winter as the time chocolate spot can begin appearing on autumn-sown broad beans.

Should You Add Fertiliser?

Not automatically.

What If Your Autumn Crop Has Failed?

Start new seeds in pots under cover.

Can February-Sown Beans Catch Up?

Yes.

The RHS explains that quick-maturing varieties started in February can harvest almost as early as overwintered plants in some conditions.

What’s My Recommendation?

Assess the health of your autumn plants and prepare a backup spring crop if necessary.

What Happens to Broad Beans in March?

March is when overwintered broad beans often become noticeably more vigorous.

Why Does Growth Improve?

Temperatures begin rising and daylight increases.

Will the Stems Become Taller?

Usually, yes.

Should You Add Stakes?

Definitely consider support before the plants become tall and vulnerable to wind.

Will Flowers Appear?

Some autumn-sown plants may begin flowering in spring, depending on the season.

What About Weeds?

Remove them before they compete heavily with the crop.

Should You Check for Disease?

Yes.

Continue monitoring for chocolate spot and other problems.

Can You Sow Another Batch?

Yes.

March is one of the main months for outdoor broad bean sowing.

How to Protect Broad Beans from Frost

Frost is one of the first things gardeners worry about when overwintering vegetables.

However, hardy broad beans are generally quite resilient.

Do Broad Beans Need Protection from Every Frost?

No.

Suitable established varieties can tolerate ordinary winter frosts.

What Is Horticultural Fleece?

It’s a lightweight covering that provides a limited amount of insulation.

Does Fleece Stop All Frost Damage?

No.

It provides some protection, not a guarantee against extreme cold.

Can You Use Cloches?

Yes.

Cloches can protect young plants from wind and cold.

When Should You Use Protection?

During particularly cold spells or where plants are exposed.

Should Covers Touch the Plants?

A supported cover may be preferable in windy conditions to reduce rubbing and crushing.

Can You Leave Fleece On During Mild Weather?

Check the plants and ventilation.

Persistent dampness under covers can create problems.

What About Snow?

After heavy snowfall, carefully check that supports and covers haven’t collapsed onto the plants.

What If Leaves Are Frost-Damaged?

Wait until conditions improve before deciding which tissue is permanently damaged.

Healthy growing points may produce new growth.

The Biggest Winter Risk: Waterlogging

For many UK allotments, waterlogging is a bigger problem than ordinary cold weather.

Broad beans prefer soil that retains some moisture but drains properly.

Why Is Waterlogging Dangerous?

Roots need oxygen.

When water fills the air spaces in the soil, roots struggle to function.

Seeds may also rot before germinating.

What Are the Symptoms?

You might see:

• Slow or stopped growth.
• Yellowing leaves.
• Wilting despite wet ground.
• Soft or rotting seeds.
• Deteriorating roots.
• Plants collapsing.

Can Broad Beans Survive Short Wet Periods?

Often, yes.

The greater danger is prolonged saturation.

Is Clay Soil Always a Problem?

No.

Clay can be fertile, but its structure and drainage matter.

Can You Improve Drainage?

Over time, mature organic matter and avoiding compaction can help soil structure.

What About Raised Beds?

Properly constructed raised beds can make overwintering more reliable where ground-level beds remain wet.

Can You Save Waterlogged Plants?

Plants with limited damage may recover when conditions improve.

Severely rotten roots or stems may not.

What’s My Recommendation?

Don’t sow directly into a bed that remains saturated for weeks. Use a better-drained area or wait until spring.

Should You Water Broad Beans in Winter?

Usually very little extra watering is needed outdoors.

Normal UK winter rainfall is often enough.

Should You Water Every Week?

No.

What If It Hasn’t Rained?

Check the soil before watering.

What About Raised Beds?

They may dry out more quickly in some situations, but don’t assume they’re always dry.

Can Polytunnel Soil Become Dry?

Yes.

Covered beds don’t receive normal rainfall.

Should You Water Pots?

Check the compost.

Water only when necessary.

Is Overwatering Dangerous?

Yes.

Persistently wet compost can cause root problems.

When Does Watering Become More Important?

Once plants begin flowering and developing pods during spring.

How Much Should You Give?

Enough to moisten the root zone when needed, without leaving the soil waterlogged.

Do Broad Beans Need Fertiliser During Winter?

Generally not.

Broad beans are legumes and can form a relationship with nitrogen-fixing bacteria in their roots.

Do They Need Nitrogen?

Yes, but they can obtain some nitrogen through biological nitrogen fixation.

Should You Use Chicken Manure Pellets?

Not automatically.

What About Onion and Garlic Feed?

There’s no special reason to use an allium fertiliser on broad beans.

Should You Feed in December?

Usually no.

What About January?

Routine feeding is unnecessary.

Should You Feed in February?

Only if soil fertility and plant condition justify it.

Can Too Much Nitrogen Be Harmful?

Excess nitrogen can encourage soft foliage growth without improving the crop.

What About Compost?

Mature compost is useful for preparing and maintaining fertile soil.

Do Container Broad Beans Need Feeding?

The RHS recommends a high-potassium liquid feed for dwarf broad beans in containers once the first flowers appear.

What’s My Recommendation?

Don’t feed every month. Maintain good soil and consider additional nutrients only when genuinely required.

Can You Grow Broad Beans Through Winter in Raised Beds?

Yes.

Raised beds are particularly useful where ordinary allotment soil drains poorly.

What Are the Benefits?

They can offer:

• Better access.
• Less soil compaction.
• Easier weeding.
• More controlled soil improvement.
• Potentially improved drainage.

Are Raised Beds Automatically Free-Draining?

No.

The growing medium and the ground beneath still matter.

Can You Sow Aquadulce Claudia in October?

Yes, when conditions are suitable.

Do You Need the Same Spacing?

Generally, yes.

Allow approximately 15–23 cm between plants.

Can You Grow in Double Rows?

Yes.

Should You Mulch?

Suitable mature compost can be used around established plants.

Avoid burying young shoots or creating excessively damp conditions.

Will the Plants Need Support?

Tall varieties usually do.

What About Strong Winds?

Raised beds in exposed sites may need particularly secure stakes.

Growing Winter Broad Beans in Pots and Containers

Broad beans can grow in containers, especially compact varieties.

However, overwintering in pots requires some care.

What Variety Is Suitable?

‘The Sutton’ is a compact option.

For overwintering, check whether your chosen variety and sowing method are suitable.

What Size Pot Do You Need?

The RHS recommends containers at least 40 cm wide.

What Compost Should You Use?

A suitable peat-free multi-purpose or loam-based potting compost.

Do Containers Need Drainage Holes?

Yes.

Can Pots Freeze?

Container root systems may experience more pronounced temperature changes than plants growing in the ground.

Should You Move Them During Severe Frost?

A sheltered position may reduce exposure.

Can You Put Pots in an Unheated Greenhouse?

Yes.

But unheated greenhouses can still become cold.

Should You Water Weekly?

Not automatically.

Check the compost first.

Do You Feed in Winter?

Generally not.

Wait until active growth and actual nutrient requirements justify feeding.

Can You Grow Broad Beans in a Polytunnel During Winter?

Yes.

A polytunnel can provide protection against wind and excess rainfall.

But there are several things to consider.

Will a Polytunnel Keep Plants Frost-Free?

No.

An unheated tunnel can still experience freezing temperatures.

Does It Help with Waterlogging?

It can prevent direct rainfall from saturating the bed.

However, ground drainage still matters.

Is Ventilation Important?

Very.

Broad bean foliage may develop fungal problems in persistently humid conditions.

Can Chocolate Spot Occur in a Polytunnel?

Yes.

Poor airflow and humidity can create favourable conditions.

Should You Water in Winter?

Check soil moisture.

Polytunnel beds may dry out because rain cannot reach them.

Do You Need to Open Doors?

Ventilation during suitable weather can reduce persistent humidity.

Will Broad Beans Need Pollination?

They can self-pollinate, but visiting insects may contribute to good pod set.

If plants are flowering under cover, consider access and ventilation.

Is a Polytunnel Better Than Outdoor Growing?

Not always.

Broad beans generally tolerate outdoor conditions, so valuable tunnel space may be better used for crops needing greater protection.

What Is Chocolate Spot on Broad Beans?

Chocolate spot is one of the most important diseases to watch for on overwintered broad beans.

It is caused by fungi including Botrytis fabae and Botrytis cinerea.

What Are the Symptoms?

Small red-brown or chocolate-coloured spots appear on leaves and other plant tissues.

What Happens in Severe Cases?

Spots may enlarge and merge.

Leaves can shrivel.

Stems may become damaged.

Severe infections can cause plants to collapse.

When Does Chocolate Spot Appear?

The RHS reports that it can appear from late winter onwards on autumn-sown broad beans.

What Weather Encourages It?

Cool, damp and humid conditions.

Does Crowding Increase the Risk?

Yes.

Crowded plants can remain wet for longer.

Can You Prevent It?

Reduce risk by allowing airflow, avoiding overly humid locations and keeping plants appropriately spaced.

Should You Use Diseased Seeds Next Year?

No.

Avoid saving seeds from infected plants.

Can Fertiliser Cure Chocolate Spot?

No.

Is There an Approved Home-Garden Fungicide?

The RHS states that no fungicides are available to amateur gardeners specifically for controlling broad bean chocolate spot.

Gardening with Ben tip: If you see brown spots appearing on winter broad bean leaves, don’t automatically assume they’re frost marks. Compare the symptoms with trusted chocolate spot identification information.

Why Are My Broad Beans Turning Yellow in Winter?

Yellow foliage doesn’t always mean the same thing.

Cold Weather

Harsh conditions may damage older leaves.

Waterlogging

Roots damaged by saturated soil may be unable to absorb nutrients normally.

Nutrient Deficiency

Poor soil can contribute to pale foliage.

Chocolate Spot

Severe fungal damage can cause leaves to deteriorate.

Other Root Problems

Damaged or decaying roots can affect the whole plant.

Should You Add Fertiliser Straight Away?

No.

Check drainage and plant condition first.

Should You Remove Yellow Leaves?

Remove badly damaged or rotting material where appropriate, but avoid stripping healthy plants unnecessarily.

Can the Plants Recover?

Yes, if the growing points and roots remain healthy.

Why Aren’t My Broad Beans Growing in Winter?

This is one of the most common concerns.

You plant seeds in October and see healthy shoots appear.

Then December arrives and the plants barely seem to change.

Is Slow Growth Normal?

Yes.

Cold weather and reduced daylight naturally slow development.

Does It Mean the Plants Are Dormant?

They may remain alive and carry out limited growth, even when little change is visible.

Should You Feed Them?

Not simply because they are growing slowly.

Should You Move Them?

Usually not.

Disturbing established roots is unnecessary.

What If the Stems Are Black or Rotten?

Investigate disease or root damage.

What Happens in Spring?

Healthy plants usually grow more vigorously as conditions improve.

When Should You Worry?

If plants show serious rot, collapse or persistent damage rather than simply slow growth.

How to Protect Broad Beans from Wind

Wind damage is another problem during winter.

Broad bean plants have upright stems that can be bent or broken.

Do Young Plants Need Stakes?

Not always.

What About Taller Varieties?

They benefit from support as they grow.

What Supports Work Best?

Strong wooden stakes and garden string.

When Should You Install Them?

Before the plants become tall and difficult to handle.

How Should You Arrange the Stakes?

Use stakes at the ends of rows and at intervals along them.

Where Should You Put the String?

Run string around the outside of the growing plants at suitable height intervals.

What About Double Rows?

The plants can offer some support to one another, but extra string is useful on windy sites.

Can Fleece Protect Against Wind?

It can reduce some wind exposure, but poorly secured fleece can flap and damage plants.

What Should You Check After a Storm?

Look for loose supports, broken stems and covers pressing against the foliage.

Should You Pinch Out Broad Bean Tips in Winter?

No, not routinely.

Pinching out broad bean growing tips is usually associated with later growth.

What Is Pinching Out?

Removing the soft growing point from the top of a stem.

Why Do Gardeners Do It?

To remove some tender growth attractive to blackfly and encourage attention towards developing pods.

When Does the RHS Recommend It?

Once the lowest flowers have formed small pods.

Should You Pinch Out Young December Plants?

No.

What About January?

Again, not as a standard practice.

Can Pinching Prevent All Blackfly?

No.

The RHS notes that pinching alone doesn’t reliably prevent infestation.

When Should You Check for Aphids?

Particularly once new spring growth develops.

What Happens to Overwintered Broad Beans in Spring?

Spring is when the rewards of autumn sowing become much more obvious.

March

Healthy plants begin making stronger growth.

Support them as needed and remove weeds.

April

Flowers may begin developing, depending on the season.

Monitor the leaves and stems for signs of disease.

May

Early pods may appear on well-established crops.

Watch for blackfly on tender growth.

June

Successful autumn crops may provide their main harvest.

Should You Water During Flowering?

Yes, during dry weather.

The RHS recommends a thorough watering when flowering begins and another around two weeks later if rainfall is insufficient.

Do Broad Beans Need Bees?

Broad beans can self-pollinate, but pollinating insects may improve pod development.

What About Blackfly?

Inspect the shoot tips regularly.

When Can You Harvest Overwintered Broad Beans?

Overwintered broad beans may provide pods as early as May in favourable seasons.

June is another common harvest month.

Is Every Crop Ready in May?

No.

Harvest dates vary by variety, site and weather.

How Do You Tell When Pods Are Ready?

The pods become plump and you can feel beans developing inside.

Can You Eat Young Pods?

Yes.

Very young, tender pods can be cooked whole.

Do Larger Pods Need Shelling?

Usually, yes.

Should You Harvest Regularly?

Yes.

Frequent picking encourages further cropping where conditions allow.

Can You Freeze Broad Beans?

Yes.

Prepared broad beans freeze well.

What Should You Do After Harvest?

Cut finished plants at soil level, leaving the roots in place if appropriate, then plan another crop for the freed growing space.

Ten Mistakes to Avoid When Overwintering Broad Beans

1. Choosing a Spring-Only Variety

Use a cultivar suitable for autumn sowing.

2. Sowing in Waterlogged Soil

Cold, saturated ground can cause seed and root rot.

3. Planting Too Closely

Crowded plants may be more vulnerable to chocolate spot.

4. Watering Every Week in Winter

Check the soil first.

5. Applying Large Amounts of Fertiliser

Routine winter feeding is rarely necessary.

6. Leaving Covers Poorly Secured

Wind-blown fleece can damage plants.

7. Ignoring Chocolate Spot

Identify unusual leaf marks early.

8. Forgetting Supports

Tall plants may be damaged by wind.

9. Pinching Out Young Plants Too Early

Wait until the crop has reached the appropriate flowering and pod-development stage.

10. Assuming Autumn Sowing Is Always Best

Spring sowing is often more dependable on wet or exposed sites.

Final Thoughts: Successfully Growing Broad Beans Through Winter

Growing broad beans through winter can be a fantastic way to make the most of your allotment during the colder months.

And there’s something incredibly satisfying about sowing seeds during autumn, looking after the plants through winter and eventually harvesting fresh broad beans when spring turns into summer.

However, success starts with choosing the right variety.

For autumn sowing, I’d particularly recommend looking at ‘Aquadulce Claudia’.

It’s a hardy variety with a good reputation for overwintering.

But even the hardiest broad bean can struggle when planted in the wrong conditions.

If your soil remains saturated throughout winter, I’d consider using raised beds or waiting until spring.

If your allotment is exposed, provide suitable shelter and support.

And if severe frosts are forecast, keep horticultural fleece or cloches available for temporary protection.

Remember that broad beans don’t need lots of attention during winter.

You don’t need to water them every week.

You don’t need to keep applying fertiliser.

And you certainly don’t need to worry because the plants appear to have stopped growing during January.

Cold weather naturally slows them down.

The important thing is to keep an eye on drainage, check for storm damage and monitor their general health.

As late winter approaches, look for chocolate spot, particularly during cool, damp conditions.

Then, as spring arrives, your overwintered broad beans should begin growing more strongly.

Support them as necessary.

Keep weeds under control.

And check for blackfly when tender growth and developing pods appear.

Once the plants begin flowering, remember that sufficient moisture can make a big difference to pod production.

Then it’s simply a matter of enjoying the harvest.

If everything goes well, you could be picking lovely broad beans during May or June.

And because they crop relatively early, you may still have time to grow another vegetable in the same bed afterwards.

For me, that’s one of the best reasons to grow broad beans through winter.

They give you something productive to look after during the colder months and something delicious to look forward to when summer arrives.

So if you’ve never overwintered broad beans before, why not try a small row this autumn?

Compare them with a spring sowing and see which performs best on your allotment.

Every growing season teaches us something new.
