There is a shastra called Virutcha Shastra in India. Every person born in this world at a particular time will be born under a particular star. A star will reside in one of the four parts of a House or Sign.
Every person will be having a tree which is beneficial to his or her birth star's position whether it is staying in 1st,2nd,3rd or 4th part of a sign . If one buys a tree according to his star position and nourishes it with care, it is said that the negative karma created will slowly vanish. While the tree grows up, the person who is nourishing it will begin to get benefit.The list of Tress,Stars,Stars Position are given in detail .See the link below which had the list in Tamil Language.
