I have Lichen but ever since it appeared my flowering tree is not doing well and has whole limbs that are dead. It has been in my yard for 7 years and just appeared last year. It is my only tree I have in my front yard and it gets sun all day and is not in a moist yard. What could it be? I know Lichen is not invasive.

    No. Lichen are a sign of distress not a cause.

    The lichen does not damage the tree. There can be several reasons a tree is dying.Has there been construction close by? People park heavy equupment under a tree or add a nice layer of dirt under the tree. Both will compress the soil and the roots will not get oxygen, so the tree dies. It looks like the tree is already too far gone... (My husband is an arborist)

      Ineke, thank you for taking the time to reply.

      No heavy equipment , only the 4' lawn mower that goes over it weekly. I hope it's not too far gone  I have to try to help it.

    Take a branch that has some of the damage on it from the tree to your local greenhouse, if you have one--they may be able to help. I use our county extension service which is associated with the state university. They diagnose issues for free on site, or for five dollars if they aren't there that day.

    It definitely has a disease. What is the name of the tree?

    • Marisa Marisa on Aug 10, 2018

      Unfortunately I have forgotten the name but what I do remember is it is a native Maryland tree and I received money back from the state 7 years ago for planting it and it has the most spectacular purple flowers (like Crepe Myrtles) that come in late spring.


      It was the best tree and want so badly to save it

    Had a similar problem, it was a tiny pest within the wood. Cut all limbs off and I can see some new growth. However, my tree was not as large as yours. I also took mine to the local county extension service for diagnosis.

    I have discovered the culprit. Root Rot

    We had 34" of rain in the month of June and my setting on my sprinkler was set for everyday by company that un winterized it and they my sensor that turns the unit off if it rains stopped working. Once I realized this I shut it off.

    The tree is a Robinia "Purple Robe" that needs well drained soil and need to dry out before rewatering. The Lichen was just a residual effect of all the moisture.


    Now can I save this beautiful tree from the root rot? I read that I should give it food and treat for pest to give it a shot so it can close the rotted roots and start new ones??


    Do we think this is necessary?
