The following are ten recommended guidelines to proper cultivation and care of vetiver.
1. Once vetiver tillers are
discovered dead, it is vital to replace them at the earliest opportunity when the climatic and soil conditions allow, such as availability of water supply, rainfalls, or soil moisture.
2. During the rainy season, the
leaves should be cut once every 60 days or before an elongation of the internode. For the dry season, cut the leaves when deemed necessary.
3. The leaves cut from vetiver which has been planted along contours across the
steep slopes are to be placed above the contour lines. For vetiver which has been planted in rows or in a circle around the bases of the fruit and perennial trees on flat land, the leaves are to be placed in between the rows or at
the tree bases respectively.
4. After having been grown for 3-4 years some vetiver tillers may die because they have been trimmed only a few times or the internodes are allowed to elongate and flower before trimming. It is
then advised to cut the vetiver in the dry season to almost the ground level and they will emerge new shoots again when the next rainy season arrives.
5. For the purpose of soil and water conservation, vetiver should be
planted tightly (for plantlets with free roots) or not more than 5 cm. apart (for plastic bag tillers). Again, the dead ones should be replaced at once for effective conservation results.
6. For vetiver cultivation on
deteriorated land with low fertility, it is recommended to fill the bottom of the plant hole with manure or compost. Once the tillers start to sprout, 15-15-15 chemical fertilizer should be added to accelerate growth at a rate of
25 kilograms per rai (0.4 acre), along the contour or above each one for slopy areas.
7. Vetiver cultivation in rows, semi-circle, or circle, should be kept at a distance of at least 1.5-2.0 m. from fruit and perennial
8. It is not recommended to plant vetiver in a thick forested area or where fruit and perennial trees have grown maturely covering the area.
9. Climbing weeds grown around vetiver should be
removed quickly because they will interfere with the growth performance and also block sunlight from reaching the vetiver.
10. For propagation purposes, vetiver should be planted in a fertile area or otherwise, 15-15-15
fertilizer should be added at a rate of 25 kilograms per rai (0.4 acre). In addition, the leaves should be trimmed regularly to prevent the roots from overgrowing which makes it difficult to dig up and remove the tillers for
