Remove
- Yellow or dried outer leaves
- Flower stalks in the second year (to briefly preserve leaf aroma)
- Infected leaves in case of Septoria fungus
Preserve
- Heart leaf (central growing point)
- Young, healthy shoots for photosynthesis
Avoid
- Clearing the entire plant at once
- Damaging the heart while cutting
Tools and hygiene
Use clean scissors to prevent the transmission of leaf spot diseases.

Cultivation specs
Seed
Spacing
Spacing notes
Sowing too densely leads to stunted growth; thin out if necessary.
Growth dimensions
Final size notes
Leaf rosette forms in the first year, flower stalk in the second.
Temperature
Temperature notes
Frost-hardy, can often be harvested throughout the winter.
Water
Critical water phases
- Germination phase
- Establishment phase
Water notes
Consistent moisture is crucial for success.
Nutrition
Nutrition notes
Avoid over-fertilizing as it weakens the aroma and promotes diseases.
Container
Container notes
Excellent for balcony planter boxes.
Support
Support notes
No support required.
Cultivation modes
Yield density
Yield notes
Yield depends heavily on variety (leaf vs. root) and cutting frequency.
Site
Exposure
Sunny to partial shade
Wind protection
Not strictly necessary, but beneficial.
Soil
Type
Humus-rich, deep, and well-drained soil
Watering
Frequency
Regularly, soil must not dry out.
Nutrition
Fertilization strategy
Basal dressing with compost before sowing; light top-dressing in summer if needed.
Cultivation planning
Succession sowing
Bed planning notes
Observe a 4-year crop rotation break (self-intolerance).
Crop rotation
Preceding crops
- Potatoes
- Tomatoes
- Onions
- Leeks
Succeeding crops
- Lettuce
- Radishes
- Brassicas
Rotation notes
Observe a 4-year break between other Apiaceae due to self-intolerance and root pests.
Deficiencies
- Slugnitrogen-deficiency
Name
Nitrogen deficiency
Symptoms
Yellowish discoloration of older leaves, weak growth.
Problems
- Sluggermination-failure
Name
Germination inhibition
Description
Seeds germinate unevenly or not at all in dry or cold conditions.
Problem management
Common pest groups
- Aphids
- Voles
- Carrot rust flies
Common disease groups
- Powdery mildew
- Downy mildew
- Leaf spot diseases
Prevention principles
- Strictly follow crop rotation
- Avoid waterlogging
- Use insect meshes against carrot rust fly
Diagnosis notes
Yellowing leaves in summer often indicate drought stress or root damage.

- Leaves
- Stems
- Roots
- Seeds (in small quantities)
Inedible or caution parts
- Plants in the flowering stage (increased apiol content)
Toxicity notes
Contains apiol; levels rise significantly during the flowering year, which can be toxic (especially to be avoided by pregnant women).
Raw consumption
Excellent for raw consumption; high vitamin C content.
Seed saving
Difficulty
Medium (due to biennial nature)
Seed collection
Harvest umbels in late summer of the second year when seeds turn brown.
Seed saving advanced
Crossing risk
Cross-pollination with wild parsley or other varieties of the same species is possible.
Seed cleaning
Shake out umbels, sieve and separate from chaff.
