Growing it

Propagation: division
When to plant: spring, early summer
Overwintering: In colder regions, cut back the foliage to 20 cm and mulch heavily to protect the crown from freezing temperatures.
In containers: It grows well in large containers, but you should use a pot at least 40 cm deep to allow for root development.

Division

Dig up a mature clump in spring.
Use a sharp spade to divide the root ball into smaller sections.
Ensure each section has healthy roots and foliage.
Replant immediately in prepared soil.

Plant vetiver on the downhill side of a garden bed to catch nutrient runoff and prevent soil loss.
