Although there is no outright cure for Bacterial Leaf Scorch yearly therapeutic treatments are used to suppress the infection and symptoms.

Therapeutic treatment for bacterial leaf scorch1) First, holes are drilled into the tree’s trunk. Although drilling holes in trees is typically a bad idea it is necessary for this process and the way the holes are drilled allows the tree to repair itself quickly without lasting damage.
2) Second, the tips of the micro-injection system are carefully inserted into the holes.
3) Once all the tips are inserted and the system is connected the tree will begin to uptake the liquid antibiotic.

By injecting the antibiotics this way, the tree’s vascular system pulls the antibiotics throughout the whole tree, suppressing the infection. Although micro-injections are a therapeutic treatment rather than a cure for Bacterial Leaf Scorch the results can be dramatic.
