How to Grow Broad Beans

Broad beans are one of the earliest and easiest vegetables to grow — hardy, productive, and delicious. They can be sown in autumn for early crops or in spring for summer harvests. With regular picking, they’ll reward you with plump pods for months.

🗓️ Month-by-Month Growing Guide (UK)

October

🌱 Autumn sowing (for early crops)

• Choose hardy varieties: ‘Aquadulce Claudia’, ‘The Sutton’, or ‘Super Aquadulce’.

• Sow directly outdoors in mild areas:

  • Sow seeds 5 cm deep, 20 cm apart, in double rows spaced 25 cm apart.

  • Space rows about 60 cm apart.

• Cover with fleece or cloches to protect from frost and birds.

• Water lightly and mark the rows clearly.

November

🧤 Overwintering

• In colder areas, sow into pots or modules and grow under cover (cold frame or unheated greenhouse).

• Keep the soil moist but not wet.

• Outdoors, check fleece covers are secure and weed around young seedlings.

December

❄️ Maintenance

• Minimal work needed — just check overwintering plants for slug or mouse damage.

• Remove any yellow or damaged leaves.

• Ventilate cold frames on mild days.

January

🌿 Preparation Month

• Clear and dig over the spring sowing area.

• Add compost or manure to enrich the soil.

• Avoid soggy ground — broad beans dislike sitting in water.

• Check autumn-sown plants — they’ll stay small but strong through winter.

February

🌾 Early Spring Sowing

• Sow seeds under cover in pots or root trainers if the soil outside is still cold.

• Use multi-purpose compost and keep them in a cold frame or greenhouse.

• In milder areas, direct-sow outdoors under fleece for early summer harvests.

March

🌱 Main Sowing Time

• Perfect month for outdoor sowing across the UK.

• Sow directly in double rows as described above.

• Protect seedlings from birds and mice with netting.

• Water after sowing and during dry spells.

April

🌿 Strong Growth

• Thin plants to 20–25 cm apart if overcrowded.

• Weed carefully and mulch around plants to retain moisture.

• Pinch out growing tips once the first flowers appear — it encourages pod set and deters blackfly.

• Stake or support taller varieties if in windy sites.

May

💧 Flowering & Feeding

• Broad beans are in flower now — fragrant and bee-friendly.

• Water generously during flowering and pod formation.

• Feed every two weeks with a liquid seaweed or comfrey feed.

• Continue to pinch out tops if blackfly appear.

June

🥕 Harvest Begins

• Pick young, tender pods regularly to encourage more growth.

• Support heavy plants with canes and string if needed.

• Water well during dry spells.

• Freeze or cook freshly picked beans right away for best flavour.

July

🍃 Peak Harvest

• Continue regular picking — small pods are sweetest.

• Once plants finish cropping, cut them down to soil level and leave roots in place (they add nitrogen to the soil).

• Compost old stems and leaves.

• Sow green manure or a quick salad crop in cleared beds.

August

🌾 End of Crop

• Clear the last plants and dig in compost.

• Plan crop rotation — don’t grow beans in the same place next year.

• You can sow autumn broad beans in late August under cover for transplanting later.

September

🌱 Prep for Next Season

• Prepare soil for autumn sowing.

• Weed, rake, and enrich the bed with compost.

• Order seed for hardy autumn varieties.

🌼 Key Growing Tips

• Soil: Fertile, well-drained, rich in organic matter.

• Sun: Full sun.

• Spacing: 20–25 cm between plants, 60 cm between double rows.

• Watering: Deeply, especially during flowering and pod filling.

• Feeding: Liquid feed every 2–3 weeks once flowers form.

• Harvest: 12–16 weeks after sowing.

• Aftercare: Leave roots in the soil — they release nitrogen for the next crop.

🌤 Tip of the Season

“Pinch out the tips once flowers appear — it keeps the blackfly away and gives you stronger pods.”
