Cardamom
Green cardamom performs best in humid tropical environments with partial shade, organic-rich soil and good drainage. Reliable moisture during inflorescence formation and flowering is particularly important because later rainfall cannot compensate fully for drought damage during these stages.
Profile
- Origin
- Southern India
- Growth habit
- Evergreen perennial herb forming clumps from underground rhizomes
- Light
- Partial shade; prolonged direct sunlight is unsuitable
- Soil
- Organic-rich, well-drained soil; waterlogging is not tolerated
- Climate reference
- PROSEA reports approximately 2500–3800 mm of uniformly distributed annual rainfall as optimal; this is not an irrigation prescription
Water & soil context
- Moisture (VWC)
- No numeric volumetric water content sensor target is provided by the cited sources.
- Salinity tolerance
- No numeric soil or irrigation-water salinity threshold is provided by the cited sources.
- Drought tolerance
- Sensitive, especially during inflorescence formation and flowering; repeated drought can endanger entire plants.
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.
Maintain consistent root-zone moisture while preserving drainage. Published rainfall ranges describe production environments, not irrigation amounts.
Problems to watch
- Katte mosaic virus and movement of infected planting material
- Rhizome and root rots under unfavorable root-zone conditions
- Thrips and shoot or capsule borers
Stress signs
- Gradual loss of vigor associated with rhizome or root rot
- Poor flower set or malformed fruits associated with severe thrips injury
- Reduced seed production following drought during reproductive development
Where you'll find it
- Culinary spice
- Tea and coffee flavoring
- Baking
