Dill
Dill is grown for fresh foliage, aromatic fruits and essential oil, with harvest timing determined by the intended product. Well-drained soil and an open canopy are important because prolonged wet conditions favor several destructive fungal diseases.
Profile
- Growth habit
- Erect herb, generally grown as an annual
- Soil
- Well-drained sandy loam or fertile loam
- Soil pH
- PROSEA describes a preferred range of 5.6–6.5
- Leaf harvest
- Generally before flowering; PROSEA gives approximately 40–50 days after sowing
- Seed harvest
- Ripening is uneven and delayed harvest risks shattering
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
- Low moisture is a recognized environmental stress, particularly during reproductive development.
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.
Avoid persistent wetness and excessively dense growth. Rainfall or water-requirement ranges in the references are not calibrated irrigation schedules.
Problems to watch
- Fusarium, Pythium and Rhizoctonia problems during prolonged wet weather
- Botrytis and Alternaria attack during flowering
- Seed shattering and uneven maturity
Stress signs
- Poor fruit set following fungal attack during wet flowering conditions
- The cited sources do not provide a reliable visual checklist specifically diagnosing irrigation or salinity stress.
Where you'll find it
- Fresh or dried dill weed
- Pickling spice
- Essential oil
