Oxytetracycline Treatment For Bacterial Leaf Scorch in Oak

[@tspfull]

is it better to do it in the spring or the fall?

You want the treatment to be at the highest concentrations in the tree during the growing season. I wait for leaf emergence because it greatly increases the Xylem activity which reduces the amount of time it takes for the tree to draw up the solution.
