Using plants to clean up contaminated soil metals is a new technology being studied in recent years. This method has the advantage of being easy to implement, does not require high technical level, low processing costs and especially environmentally friendly. Therefore, the in – situ treatment method use plant is promising direction. This article presents some results of studies on the growth, development and absorption of vetiver fuse under the influence of the concentration of lead in different soils. Vetiver still capable of good growth and development in the concentration of Pb in soil from 700 - 2800ppm with no difference compared with the control sample height and biomass. After 30 days treatment, levels of lead in the soil remaining from 72.65% - 74.73% after 60 days of treatment remaining 51.83% - 56.47% after 90 days of treatment lead content land is only 44.85% - 47.58%.
