Just read the book on Bazi. My question: if my Bazi indicated excess earth elements, with only 1 wood & 1 metal element. Obivously, I need water & metal as well as wood to balance out. At my home, if i want to have live growing plants, which is the best location for it? Beside waering black, blue & white, any other things needs to be done?

Dear Khong, that depends what season you are in. Earth in summer is different from earth in spring, autumn, or winter. The number is less important. Plants will not affect you or you BaZi. No worries on colours too. It may affect your psyhcology, but not your luck directly. Cheers! SN
