Direct sowing
Direct sowing into the open ground from mid-May, once the risk of frost has passed and the soil has warmed up.
Planting
Pre-cultivated plants can be transplanted outdoors from mid-May, provided night temperatures are consistently above 10°C.
Harvest
Harvest is continuous as soon as the beans reach the desired size. For bush beans, harvest multiple times; pole beans often produce until the first frost.
Year plan
- Prepare soil and incorporate compost if necessary.
- Direct sowing into the open ground or transplanting pre-cultivated young plants.
- Water regularly during dry periods.
- Weed, taking care not to damage young plants.
- Regular harvesting to encourage further flowering.
- Watch for pests such as aphids and spider mites.
- Continuous harvesting.
- Continue watering during prolonged dry spells.
- Final harvest before the first frost.
- Remove plant debris and compost (unless diseased).

Storage
Storage methods: Refrigeration, Freezing (after blanching), Canning/Preserving, Drying (mature seeds only)
Pro tips: Only sow beans when the soil temperature is at least 12°C, otherwise the seeds often rot in the ground., Slightly earthing up the young plants (about 10 cm high) improves stability.

Yield optimization and hygiene Regular picking every 2-3 days acts like maintenance pruning and stimulates new flower production.
Remove
- Dead or yellowing leaves to improve air circulation
- Diseased plant parts (dispose of immediately)
- Plant debris after the final harvest
Preserve
- Main shoot of pole beans
- Flower buds
- Root nodules in the soil after season end (nitrogen fixation)
Avoid
- Topping the shoots before they reach the trellis height
- Harvesting or handling during wet weather (fungal risk)
- Damaging shallow roots during hoeing
Tools and hygiene
Use sharp shears to avoid crushing sensitive shoots; disinfect tools after contact with anthracnose.

FAQ
Can you eat common beans raw?
No, never! Common beans contain phasin, a toxic protein that is only destroyed by boiling for at least 10-15 minutes.
Why are my beans flowering but not setting fruit?
Common causes are extreme heat above 30°C or severe drought during the flowering period.

Book content
Short portrait
The common bean is an indispensable classic in the vegetable garden, valued for its nutritious pods and ease of cultivation. Whether as a compact bush bean or a tall climbing pole bean, it enriches every garden and sustainably improves soil quality through nitrogen fixation.

Cultivation specs
Seed
Spacing
Spacing notes
Spacing varies by variety (bush vs. pole bean). Pole beans require more space per plant and a climbing support.
Growth dimensions
Final size notes
Bush beans are shorter (30-60 cm), while pole beans can climb up to 2-3 meters.
Temperature
Temperature notes
Beans are very frost-sensitive and require warm temperatures for optimal growth.
Water
Critical water phases
- Flowering
- Fruit development
Water notes
Consistent watering is crucial, especially during flowering and fruit development. Avoid waterlogging at all costs.
Nutrition
Nutrition notes
As legumes, beans can fix nitrogen from the air. However, good basic supply of phosphorus and potassium is important. Avoid over-fertilization with nitrogen.
Container
Container notes
Suitable for bush beans and smaller pole bean varieties. Adequate pot size and good drainage are important.
Support
Support types
- stake
- trellis
- arch
Support notes
Pole beans require stable supports such as poles, nets, or trellises. Bush beans do not need support.
Cultivation modes
Yield density
Yield notes
Yields can vary significantly depending on variety, location, and care.
Site
Location
Sunny to partially shaded
Wind protection
Preferably wind-protected, especially for pole beans.
Notes
A warm, sunny location promotes growth and yield. Partial shade is tolerated but may reduce yield.
Soil
Type
Humus-rich, loose, well-draining, nutrient-rich
PH range
Notes
Beans prefer deep, warm soils. Avoid heavy, cold soils. Loosen the soil well and enrich with compost before sowing or planting.
Watering
Frequency
Regularly, especially during dry spells and during flowering/fruiting.
Method
Best at the root zone to prevent fungal diseases.
Notes
Consistent moisture is important. Avoid waterlogging at all costs. Daily watering may be necessary in hot weather.
Nutrition
Fertilization
Good basic supply with compost before planting. If needed, fertilize during the growing season with organic liquid fertilizer.
Notes
As legumes, beans require little nitrogen. Focus on phosphorus and potassium. Avoid over-fertilization with nitrogen, as this can lead to excessive leaf growth and poor fruiting.
Cultivation planning
Succession sowing
Bed planning notes
Beans are good predecessors for many vegetables. Do not plant after other legumes (observe crop rotation).
Crop rotation
Successors
- Brassicas
- Celery
- Leeks
- Lettuce
Predecessors
- Heavy feeders
- Potatoes
- Tomatoes
Notes
Beans leave valuable nitrogen in the soil. A rotation break of 3 years from other legumes must be strictly observed.
Deficiencies
Nitrogen
Stunted growth and pale leaves (rare due to nitrogen fixation).
Manganese
Yellow spots between leaf veins in lime-rich soils.
Problems
Environmental
- Typecold_shock
Label
Cold shock
Description
Growth stops at temperatures below 10°C.
- Typeflower_drop
Label
Flower drop
Description
Often caused by extreme drought or heat.
Problem management
Common pest groups
- Aphids
- Spider mites
- Bean weevils
Common disease groups
- Fungal diseases (Rust, Anthracnose)
- Viruses (Mosaic virus)
Prevention principles
- Observe crop rotation
- Do not work or harvest when wet
- Choose resistant varieties
- Ensure adequate spacing for air circulation
Diagnosis notes
Spots on pods usually indicate fungal infection; leaf deformations often suggest aphids or viruses.

- Pods
Prevention
- Use certified seed
- Crop rotation
Organic control
- Remove infested plants immediately
- Horsetail tea
Diagnostic rules
Symptom
Sunken, dark spots with light borders on the pods
Possible causes
- colletotrichum-lindemuthianum
First checks
- Was it harvested in the rain?
- Is the seed home-grown?
Prevention strategy
Cultural
- Respect rotation breaks
- Keep soil loose
Monitoring
- Weekly check of leaf undersides
Organic first response
- Hosing down with water for aphid infestation
- Use of beneficial insects
Notes
Prevention is more important than cure for beans, as many diseases are seed-borne.
Diagnosis
Common misdiagnoses
Sunburn on young leaves is often misinterpreted as a viral disease.

Yield estimate
1.5–3 kg per square meter
Harvest details
Harvest frequency
Pick every 2–3 days to stimulate the production of new pods.
Harvest indicators
- Pods snap cleanly when bent (snap test)
- Seeds are not yet visible or only faintly bulging
- Smooth surface and vibrant pod color
Post harvest handling
Store beans in a cool place after harvest and process quickly; harvest in dry weather to avoid disease transmission.
Storage
Storage methods
- Refrigeration
- Freezing (after blanching)
- Canning/Preserving
- Drying (mature seeds only)
Storage details
General storage category
Short-term storage (fresh) or long-term storage (preserved/dried)
Storage life
Fresh: 2–4 days in the refrigerator; Frozen/Canned: 12 months; Dried beans: Several years.
Processing options
- Blanching and freezing
- Lactic acid fermentation
- Pressure canning
- Drying mature seeds
Processing use
Primary use
Cooked vegetable
Kitchen usage
Preparation tips
Always boil beans for at least 10-15 minutes to destroy the toxic phasin.
Dish examples
- Bean salad with onions and summer savory
- Green beans with bacon
- Stews
- Buttered green beans
Safety and edibility
Edible parts
- Young pods
- Mature seeds
Inedible or caution parts
- Raw pods
- Raw seeds
Toxicity notes
Contains the protein phasin, which causes severe gastrointestinal distress. It is only neutralized by heating.
Raw consumption
Never consume raw!
Seed saving
Difficulty
Easy
Seed saving advanced
Method
Allow the best pods to dry completely on the plant until the seeds rattle when shaken.
Selection criteria
Only harvest from healthy, high-yielding plants without signs of anthracnose.
Woody crop details
Notes
As an annual herbaceous plant, the common bean does not develop woody structures. Classification is primarily based on bush and pole growth habits.
Ecology
Biodiversity notes
Bean flowers provide nectar for bumblebees and wild bees. As legumes, they improve soil life through symbiosis with rhizobia.
Practical notes
Pro tips
Only sow beans when the soil temperature is at least 12°C, otherwise the seeds often rot in the ground.
Slightly earthing up the young plants (about 10 cm high) improves stability.
Seasonal content
Spring
Prepare soil, set up climbing frames.
Summer
Peak time for irrigation and continuous harvesting.
Autumn
Wait for seed maturity for home seed saving.
Winter
Check storage of dried seeds.
