Vetiver is drought-tolerant once established. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Reduce watering significantly during cooler months to prevent root rot.

Ensure good drainage to avoid waterlogging.

Pruning is minimal and mainly for aesthetic purposes or to manage size. Trim back old or damaged foliage in late winter or early spring before new growth emerges. This encourages a tidy appearance and healthier regrowth.

Vetiver is typically propagated by dividing established root clumps. This can be done in spring. Ensure each division has sufficient roots and shoots for successful establishment in its new location.

Repotting is rarely necessary for outdoor plantings due to its extensive root system. For container-grown plants, repot every 2-3 years into a larger container with fresh, well-draining soil as needed, usually in spring.
