You can prune the tree to allow more light. The extra light can help kill the lichen. Or you can use copper sulfate. Make sure you do this in the late fall or winter season and wear protective clothing.

∙ 6y agoStubborn homeowners who see that prized "specimen" tree covered with lichens may be willing to take some action to try and remove a vigorous lichen overgrowth. Lichens thrive in a moist environment. While you can't change the weather, you can change your watering habits if you have a sprinkler system. The same sprinklers that are good for your lawn, promote the growth of lichens on trees. Less frequent, but longer sessions with your sprinkler will decrease the water on your tree branches. Also pruning, to let more light into the center of the tree, may be helpful to more quickly burn off that morning dew.
Lichens can physically be brushed off using a very gentle brush or scraping with a soft wood chip. Obviously, you don't want to harm the trees branches with overzealous scraping. Copper sulfate seems to be the agent most commonly applied. Like any poison, directions for use need to be carefully followed. While it can be sprayed, copper sulfate is irritating to eyes, and interferes with photosynthesis on leaves. Therefore, it has been suggested that it be "painted on". Copper accumulates in the soil, and is very toxic to fish through groundwater runoff. Therefore copper sulfate use is not to be taken lightly, and probably should be considered more as a one time application rather than a step that can be regularly repeated to control vigorous lichen overgrowth.
So removing a heavy overgrowth of lichens from a favorite ornamental tree or two may be barely practical for that stubborn homeowner who can't stand to see that expensive tree from the nursery covered in lichens. But it will only be a temporary fix, unless they do some pruning or change their watering habits to correct the underlying cause for the lichen overgrowth. And if you live in a very humid environment, it is probably hopeless to get involved in a never ending war against mother nature.
More Information:
I am convinced that lichen is harmful to trees and I have tried a few things to get rid of it. Copper sulphate is what is recommended by garden centres but I have found it to be pretty near useless. I have watched my lovely pohutakawa tree suffering with thick lichen all over and could take no more. I got out the water blaster and managed to irradicate nearly all of it. What a huge difference it has made. I have masses of new growth and more flowers than ever before.
