Growing Broad Beans: Sowing, Care, Pests and Harvest

Garden broad bean is a traditional vegetable that is slowly falling into oblivion. However, this legume deserves our attention not only for its exceptional nutritional value, but also for its ease of cultivation and ability to improve soil quality. In this comprehensive guide, you'll learn everything you need to know about growing garden broad beans – from soil preparation to harvest and use in the kitchen.

What is Garden Broad Bean and Why Grow It?

Garden broad bean (Vicia faba), also known as fava bean or horse bean, is one of the oldest cultivated plants in Europe. This annual legume can reach heights of 60-150 cm depending on the variety. Its distinctive features include upright growth, grey-green leaves and white flowers with characteristic black spots.

Main benefits of growing broad beans:

Nutritional richness – high protein, fibre and B vitamin content
Nitrogen fixation – improves soil quality for subsequent crops
Frost resistance – can be sown very early in spring
Low demands – suitable for beginners
Versatile use – fresh, dried or frozen consumption

Choosing the Right Variety

Broad beans are divided into several types according to seed size and intended use:

Large-Seeded Varieties

These varieties have large, flat seeds and are ideal for fresh consumption. They mature later but offer the best taste. Popular varieties include 'Hangdown Giant' and 'Imperial Green Longpod'.

Medium-Seeded Varieties

Universal varieties suitable for both fresh and dried consumption. They offer a good balance between yield and taste quality. Try varieties like 'The Sutton' or 'Aquadulce'.

Small-Seeded Varieties

These are mainly used for drying and animal feed. They are the most productive but have lower culinary value.

Soil Preparation and Sowing

Success in growing broad beans starts with proper soil preparation. Broad beans prefer heavy clay soils with neutral to slightly alkaline pH (6.5-7.5).

Soil Preparation Steps:

Dig the bed in autumn to a depth of 25-30 cm
Work in compost or well-rotted manure (3-4 kg per m²)
In spring, work in wood ash to supply potassium
Level and firm the surface before sowing

Sowing Date

Broad beans are among the earliest vegetables you can sow:

Autumn sowing (October-November) – for very early harvest in milder areas
Early spring sowing (February-March) – most common method
Successive sowing (until May) – for continuous harvest

Sowing Technique

Broad beans can be sown directly outdoors or pre-germinated:

Sowing depth: 5-8 cm
Row spacing: 40-50 cm
Plant spacing in row: 10-15 cm
Seed requirement: approximately 20-25 seeds per 1 m²

Tip: Pre-soaking seeds in water for 24 hours before sowing speeds up germination.

Cultivation and Care

Although broad beans are undemanding, proper care significantly increases yield and quality.

Watering

Broad beans have deep roots and are relatively drought-resistant. However, regular watering is important during flowering and pod development. Water thoroughly but less frequently – approximately 20-30 litres per m² weekly during dry periods.

Feeding

As legumes, broad beans fix atmospheric nitrogen and therefore don't need much nitrogen fertilisation. Focus instead on:

Phosphorus – supports root development and flowering
Potassium – improves pod quality and plant resistance
Magnesium – important for chlorophyll formation

Apply a complex vegetable fertiliser with lower nitrogen content during bud formation.

Supporting and Pinching

Taller varieties need support to prevent lodging. Use stakes or stretch string between posts along rows. When plants reach the desired height (usually when the first pods form), pinch out growing tips. This encourages pod development and helps prevent black bean aphid infestation.

Weeding and Mulching

Regular weeding is important, especially in the early growth stages. Once plants are well established, apply a layer of mulch around them to:

Suppress weed growth
Retain soil moisture
Stabilise soil temperature

Pest and Disease Protection

Black Bean Aphid

The most common broad bean pest. Black aphids colonise the growing tips and young pods. Prevention:

Pinch out growing tips when pods form
Support beneficial insects (ladybirds, lacewings)
Grow companion plants (nasturtiums, marigolds)
Spray with soapy water solution in case of mild infestation

Chocolate Spot

Fungal disease manifesting as brown spots on leaves. Prevention is better than cure:

Ensure sufficient plant spacing for good air circulation
Avoid overhead watering
Rotate crops – don't grow beans in the same spot more than once every 4 years
Remove and destroy affected plants

Harvesting and Storage

When to Harvest

The harvest period depends on sowing date and intended use:

Young pods (whole consumption) – 8-10 weeks after sowing
Fresh beans (green seeds) – 12-16 weeks after sowing
Dried beans – 20-24 weeks after sowing, when pods turn black

For fresh consumption, harvest when seeds are fully developed but still soft. Pods should be firm and green.

Storage Methods

Fresh beans:

Store in refrigerator for up to 5 days
Blanch and freeze for long-term storage

Dried beans:

Leave pods on plants until completely dry
Shell and dry seeds in a warm, airy place
Store in airtight containers in a cool, dry place

Culinary Use

Broad beans are a versatile ingredient offering many culinary possibilities:

Young Beans

Young, small beans can be eaten whole including the pod. Prepare them similarly to green beans – boil, steam or sauté.

Green Beans

Larger green seeds are best after removing the outer skin. Use them in:

Salads and side dishes
Purees and patés
Risottos and pasta
Soups and stews

Dried Beans

Dried broad beans need longer cooking (1-2 hours after overnight soaking). They're ideal for:

Traditional stews and soups
Vegetarian burgers and patties
Spreads and dips

Broad Beans in Crop Rotation

Broad beans are an excellent preceding crop for many vegetables. Thanks to nitrogen fixation, they leave soil enriched with this important nutrient. Ideal crops to follow broad beans include:

Brassicas (cabbage, broccoli, cauliflower)
Leafy vegetables (lettuce, spinach)
Fruiting vegetables (tomatoes, peppers)
Root vegetables (carrots, beetroot)

After harvest, don't pull up plants but cut them at ground level. Leave roots in soil to decompose and release fixed nitrogen.

Conclusion

Growing garden broad beans is rewarding for any gardener. This traditional vegetable offers high nutritional value, improves soil quality and is easy to grow. With proper variety selection, timely sowing and basic care, you can look forward to a bountiful harvest of fresh, healthy beans. Don't let this valuable crop fall into complete oblivion – give broad beans a place in your garden and discover their unique taste and benefits.

Broad bean (Faba vulgaris) is a plant from the legume family (lat. Fabaceae). In new terminology, broad bean has been renamed faba bean (lat. Vicia faba) and was classified into the vetch family (lat. Viciaceae) of plants. Another name, especially used frequently in the past, is horse bean. Broad bean is a very important agricultural crop that is grown in temperate climate zones.

Three basic forms of this crop are distinguished according to seed (bean) size

Garden bean, also called Windsor bean (lat. Vicia faba var. major). This form of bean is grown as a vegetable in gardens and in large-scale agriculture for food processing.

Horse bean, also called field bean (lat. Vicia faba var equina), is incorporated into feed mixtures for animals. So-called "hot-air drying products" are made from it.

Small-seeded bean, also called pigeon bean (lat. Vicia faba var minor), is more suitable as a pre-crop and green manure.

Bean flowers are three-lobed, resembling a trefoil.

What does a bean plant actually look like?

A well-developed bean plant can be up to 1 meter tall and have a massive inflorescence. Bean flowers are white, self-pollinating, and can be up to 4 cm. Elongated, brownish-black pods develop from the flowers. The leaves of the broad bean resemble clover and are trifoliate. The root system is not very extensive, so when growing in a garden, it is recommended to hill up soil around the stems.

Where did the bean come from?

Broad bean originates from North America and Southwest Asia. In the eastern Mediterranean, it was commonly consumed as early as 6000 BC. It spread to Central Europe later, but was never grown too massively.

Grow broad beans in your garden!

You can grow broad beans in your garden from seeds available in our e-shop. Broad bean is a plant resembling beans, with white flowers. Pods containing white fruits - beans develop from the flowers. Beans taste excellent and have a delicate, floury texture. Beans thrive best in previously fertilized, loose soil.

Beans taste excellent and have a delicate, floury texture.

What conditions does broad bean prefer?

Broad bean has the highest soil quality and climate requirements of all legumes, yet its cultivation is not complicated. Broad bean thrives best in heavy, clay-loam soils that are rich in calcium and other nutrients. The suitable soil pH should be neutral, ranging from 6.8 to 7. Broad bean is not demanding in terms of heat, so it does well even at higher altitudes. The only risk here is late ground frosts, which could damage the broad bean. In the initial growth phase, mild ground frosts don't harm the broad bean. Broad bean has high water requirements. Broad beans need an increased amount of water during the early growth period, as this is when the most green mass is formed. Older plants grow more slowly, so the required water dose also decreases.

Sowing broad bean

Broad bean is sown directly into the soil early in spring. Seeds begin to germinate at temperatures just above freezing, so they can be sown as early as February and March. Mild ground frosts (approximately down to -4°C) are easily survived by broad beans. Broad beans are planted at a spacing of approximately 50 x 80 cm. 2-3 seeds are always sown in one spot. After germination, it's necessary to provide young seedlings with sufficient water so they can develop well. Keep broad bean beds free of weeds.

Broad beans produce a large amount of green mass, which is used as "green manure"

Broad bean as a soil improver

Broad bean is used to improve soil in two ways. Mature broad bean plants have a large amount of green mass, which becomes so-called "green manure" after being dug in, enriching the soil with important nutrients. Another enormous benefit for the soil is broad bean's ability to fix atmospheric nitrogen on nodule bacteria on the roots. Broad bean is a good preceding crop and an excellent cover crop, as vigorously growing young broad beans don't allow weeds to grow. Broad bean should not be grown in the same place for more than 4 years.
