Cumin
Cumin is cultivated for dry fruits commonly called seeds and generally suits a relatively cool, dry growing season with full sun. It is frost-sensitive, requires good drainage, and benefits from crop rotation because soilborne wilt and other diseases can limit production.
Profile
- Origin
- Mediterranean region
- Life cycle
- Annual
- Season
- Approximately three to four months; NC State describes about 120 frost-free days
- Soil pH
- PROSEA reports an optimal range of 6.8–8.3
- Planting
- Seed-propagated; transplanting can be difficult
Water & soil context
- Moisture (VWC)
- No numeric volumetric water content sensor target is provided by the cited sources.
- Salinity tolerance
- No numeric salinity tolerance threshold is provided by the cited sources.
- Drought tolerance
- Adaptation to relatively dry climates should not be interpreted as immunity to moisture stress; no numeric drought threshold is supplied.
Illustrative monitoring-depth band
3–8 in
Editorial placement example, not a validated optimum or total rooting depth. Confirm the site's root distribution and soil horizons; multiple depths may be needed.
NC State advises regular watering while allowing soil to approach dryness between waterings. This qualitative garden guidance is not a calibrated field sensor target.
Problems to watch
- Fusarium wilt
- Powdery mildew and Alternaria blight
- Aphids and fruit-feeding insects
Stress signs
- The cited sources name important diseases but do not provide a reliable visual checklist distinguishing water, salt and disease stress.
Where you'll find it
- Whole or ground culinary spice
- Essential oil flavoring
