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.

AugSep

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.

Harvest details
Harvest frequency

Leaves can be harvested regularly as needed, as long as the heart of the plant remains intact.

Harvest indicators
  1. Leaves: Reaching sufficient size (approx. 10-15 cm)
  2. Seeds: Color shift from green to light brown
  3. 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).

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.

Notes

As an annual herbaceous plant, coriander does not undergo lignification; classic fruit tree pruning principles are not applicable.
