All plants
Indoor sowingDirect sowingPlantingHarvest

Direct sowing

MayJun

Direct sowing into the open ground from mid-May, once the risk of frost has passed and the soil has warmed up.

Planting

May

Pre-cultivated plants can be transplanted outdoors from mid-May, provided night temperatures are consistently above 10°C.

Harvest

JulAugSep

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
  1. Prepare soil and incorporate compost if necessary.
  2. Direct sowing into the open ground or transplanting pre-cultivated young plants.
  3. Water regularly during dry periods.
  4. Weed, taking care not to damage young plants.
  5. Regular harvesting to encourage further flowering.
  6. Watch for pests such as aphids and spider mites.
  7. Continuous harvesting.
  8. Continue watering during prolonged dry spells.
  9. Final harvest before the first frost.
  10. Remove plant debris and compost (unless diseased).

Growing

Common bean Site, soil and care

Spacing

10 - 15 cm

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.

Pruning timing

summer

JulAugSep

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.

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
Min.6
Max.7
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.

Notes

Prevention is more important than cure for beans, as many diseases are seed-borne.

Harvest details
Harvest frequency

Pick every 2–3 days to stimulate the production of new pods.

Harvest indicators
  1. Pods snap cleanly when bent (snap test)
  2. Seeds are not yet visible or only faintly bulging
  3. 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 life

Fresh: 2–4 days in the refrigerator; Frozen/Canned: 12 months; Dried beans: Several years.

Processing options

  2. Lactic acid fermentation
  3. Pressure canning
  4. Drying mature seeds
Processing use
Primary use

Kitchen usage
Preparation tips

Always boil beans for at least 10-15 minutes to destroy the toxic phasin.

Dish examples

  2. Green beans with bacon
  3. Stews
  4. Buttered green beans
Safety and edibility
Edible parts
  1. Young pods
  2. Mature seeds
Inedible or caution parts
  1. Raw pods
  2. 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

Isolation distance5 m
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
Pollinator valuemedium
Wildlife valuelow
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
  1. Only sow beans when the soil temperature is at least 12°C, otherwise the seeds often rot in the ground.

  2. 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.
