Only use copper-sulfate as a treatment for tree lichen in late spring through early fall. It will not be effective in cool weather. You can also remove tree lichen with lime sulfur. Lime sulfur is also used to kill the fungus that makes up half of the lichen.Be careful that the lime sulfur is not applied to either the roots or the leaves of the tree, as this can damage the tree.nly use copper-sulfate as a treatment for tree lichen in late spring through early fall.

A photo of the dam from County Route 7. Location of Conklingville Dam in New York Adirondack Park. The Conklingville Dam, in Hadley, Saratoga County, New York, is an earthen dam which holds back the Great Sacandaga Lake (in the town of Day, New York). The dam, completed in 1930, is owned by the Hudson River-Black River Regulating District.
The dam impounds Lake Oroville, the second largest man-made lake in the state of California, capable of storing more than 3.5 million acre-feet (4.4 km3), and is located in the Sierra Nevada foothills east of the Sacramento Valley.
