How to Propagate Vetiver

There are many methods of propagation. Plants produced from a nursery whatever the size are generally of better quality. Experienced/traditional small farmers often just split their existing hedgerows using the downhill vetiver part of the hedge as transplants for new hedgerows. This system works under proper management and small numbers. Production of large numbers of quality and uniform slips should come from nurseries.  The cheapest and in most cases the best is production of bare rooted plant material. Vetiver in Thailand was successfully propagated (by the millions) in-vitreo, but even these should go through a nursery phase. Containerized plants are very good, but more expensive, and are recommended for use where the site conditions warrant them. Some of the other methods of propagation can be found in Document Center papers. The following photos show a step-by-step process of producing bare rooted vetiver slips. We thank Evan Millwood of Queensland, Australia for many of the photos.

Photo 4 A well managed nursery. Plants are irrigated and trimmed regularly to encourage tillering. Planting distances vary but a planting density of 60,000 plants/ha should be the target
Photo 5 Most nurseries are small and simple like this one that produces containerized vetiver plants. Their plants if properly grown are just as good as those from large commercial growers.

Photo 7 Dig the trimmed clump
Photo 8 Cut the soil away from the clump sides leaving 5 cm of root below the crown
Photo 9 The group of tillers (slips) in your hand should be further divided to get groups of at least three tillers that becomes the basic transplanting unit
