Black tar disease on maple

Asked October 10, 2018, 8:59 AM EDT

My question is: Is there something I can do organically to strengthen tree to fight disease? I've read about removing diseased leaves to prevent infestation. But my area is heavily wooded and impossible treat on a city wide treatment plan.
