Conseils de culture
Roots must be at least 18 months old for oil extraction; older roots (24+ months) yield higher quality oil with more desirable sesquiterpene compounds.
Plant in dense hedgerows for erosion control on slopes — vetiver hedges reduce runoff by 70% and trap sediment effectively.
Vetiver is non-invasive (sterile cultivars available) and tolerates extreme soil conditions including salinity, acidity, and heavy metal contamination.
