how to make wisteria into tree?
Hello everyone I am new to this forum and new to the art of bonsai. I have always been in love with nature and finally found an art form that lets me express my self and enjoy the gift of nature. I am growing Japanese Blue Wisteria from seeds. I planted them in the end of March and now I have 3 baby wisteria vines. My question is when and how do I turn the vine into a tree?
