Years ago I transplanted two palm trees, and after months they looked terrible. I went to a nursery and the old man there told me of a mixture (which I forget but one of the items I'm sure was liquid copper). There was either two or three ingredients and I believe along with some water, you poured this into the center of the tree. I know within months those two palm trees started looking great and to this day when I ride by where I used to live they are beautiful trees. Would appreciate any ideas. Thank you.
