CorianderCoriandrum sativum
Coriander is an essential culinary herb valued for both its fresh leaves and aromatic seeds. While straightforward to grow, it is prone to 'bolting' or premature flowering during hot weather. The best way to ensure a continuous harvest of fresh greens is through successive sowings every three weeks.

Continuous harvest and vitality Regular picking of leaves slightly delays bolting.
seed_harvest
Seed collection Cut the entire umbel once seeds are brown and dry.
Remove
- Individual leaves as needed
- Bolting stems (if only leaves are desired)
- Yellowing or diseased leaves at the base
- Mature seed umbels in late summer
Preserve
- The heart of the plant (growing point) for regrowth
- Flower stalks if seed production is intended
- Lower third of the plant during partial harvest
Avoid
- Total clear-cutting of the plant before seed maturity
- Pruning during extreme midday heat (wilting risk)
- Damaging the taproot during weeding or harvesting
Tools and hygiene
Use clean scissors to avoid crushing soft stems and to prevent bacterial leaf spot.

FAQ
Why does coriander taste like soap to some people?
This is due to a genetic variation (OR6A2 gene) that causes aldehydes in coriander to be perceived as soapy.

Cultivation specs
Seed
Spacing
Spacing notes
Closer spacing encourages leaf production, wider spacing encourages seed production.
Growth dimensions
Final size notes
Flowering plants grow significantly taller than the initial leaf rosette.
Temperature
Temperature notes
High temperatures trigger bolting (flowering).
Water
Critical water phases
- Germination phase
- Leaf development
Water notes
Consistent moisture prevents premature bolting.
Nutrition
Nutrition notes
Excess nitrogen reduces the aroma of the leaves.
Container
Container notes
Choose deeper pots due to the taproot.
Support
Support notes
Usually stable, except in extreme wind during seed ripening.
Cultivation modes
Yield density
Yield notes
Seed yield is approx. 10-20g per plant.
Site
Sun exposure
Full sun to partial shade
Wind protection
Protected, especially during flowering
Soil
Texture
Well-drained, humus-rich, loamy-sandy
PH range
Watering
Frequency
Regularly, never let soil dry out completely
Nutrition
Fertilization strategy
Small applications of compost before sowing are usually sufficient.

Succession sowing
Bed planning notes
Good companions: Cabbage, beetroot, lettuce. Poor companions: Fennel.

Notes
Do not grow after other umbellifers to prevent soil fatigue and disease buildup.

Name
Nitrogen deficiency
Symptoms
Pale green to yellowish discoloration of older leaves.
Problems
- Slugvorzeitiges-schossen
Name
Premature bolting
Description
Plant goes to seed too quickly, usually due to heat or drought stress.
Problem management
Common pest groups
- Sucking insects
- Soil-borne larvae
Common disease groups
- Fungal diseases
- Bacterial pathogens
Prevention principles
- Consistent soil moisture
- Wide spacing for ventilation
- Follow crop rotation
Diagnosis notes
In case of wilting, first check soil moisture and roots for pest infestation.

Leaves turn yellow and plant immediately forms flower stalks.
Possible causes
- Trockenstress
- Hitzestress
First checks
- Check soil moisture
- Monitor site temperature
Prevention strategy
Cultural
- Prefer direct sowing
- Mulching to retain moisture
Monitoring
- Weekly check for aphids
- Observation of leaf undersides
Organic first response
- Rinse with water for light aphid infestation
- Remove affected plant parts early
Notes
Coriander is short-lived; often resowing is more sensible than intensive treatment.
Diagnosis
Common misdiagnoses
- Bolting is often misinterpreted as nutrient deficiency.
Phenology
Stages
- Germination
- Leaf rosette formation
- Stem elongation (Bolting)
- Umbellate flowering
- Fruit development (Green seeds)
- Seed ripening (Browning)
- Plant senescence
Notes
Annual plant with a rapid development cycle, especially during warm weather.

Flowering period

Flower color
White to pale pink
Inflorescence type

Harvest
Leaf harvest period
Continuous from June until frost
Seed harvest period

Harvest details
Harvest frequency
Leaves can be harvested regularly as needed, as long as the heart of the plant remains intact.
Harvest indicators
- Leaves: Reaching sufficient size (approx. 10-15 cm)
- Seeds: Color shift from green to light brown
- Seeds: Emit a pleasant spicy scent instead of the 'bug-like' smell of unripe seeds
Post harvest handling
Use leaves immediately or place in a glass of water. Allow seeds to fully air-dry after harvest.
Storage
Fresh storage
In the refrigerator in a damp cloth for approx. 2-3 days.
Dried storage
Store dried seeds in a cool, dark, and airtight container (up to 2 years).

Toxicity notes
No toxicity known for common consumption. Due to genetics, some people perceive the taste as soapy.
Raw consumption
Leaves and young stems are mostly used raw as a garnish or in salads.
Seed saving
Isolation distance
No crossing with other herbs except other coriander varieties.
Extraction method
Hang whole seed umbels in a paper bag and let dry until the seeds drop off.
Seed saving advanced
Purity maintenance
Use at least 5-10 plants for seed saving to maintain genetic diversity.
Woody crop details
Notes
As an annual herbaceous plant, coriander does not undergo lignification; classic fruit tree pruning principles are not applicable.
Ecology
Biodiversity notes
The open umbel flowers are particularly attractive to hoverflies and parasitic wasps, which are natural predators of aphids.

- Resow every 3 weeks.
- Do not transplant as the taproot is sensitive.
- Seeds only smell pleasant after drying.
