hello everyone! my name is Trung, I'm from Vietnam, I'm student. I want to ask you what chemicals can excite trees to bloom? in my province there is a tree called GREEN DRAGON tree, do you know this tree? there is also a chemical called VSL1. After reject thorn of tree, we smear this chemical (VSL1) onto it. Four or five days later, the tree will bloom. Because chemical component of VSL1 is very secret, I'm so curious about its components. Would you like to help me! Thank you so much!
