Hi-Yield Muriate of Potash 0-0-60 is not labeled for use on trees to target lichen, so we can not recommend it for this purpose. We would recommend reaching out to an arborist in your area, a local tree nursery or to your to local cooperative extension office to inquire about treatment options for lichen on your trees.
