Her Royal Highness asked where to do. I said at the same place where she used to do her project and a part of which was the mountains. I meant the place which she liked a lot and that was Doi Tung. I said that if this grass was not used there, the conditions of the land would not be good. She was not sure how the grass could make things good. Normally, wherever a kind of grass covers, the land would turn unproductive. However, for the vetiver grass, if we choose the right ecotype and grow in a proper pattern, the grass will flourish amazingly and it can help turn the land productive and useful. Then I told her about the methods of planting and selecting the ecotypes.
