I have 3 cedar trees- over 10 years old. The one in the middle is suddenly going very brown on one side. What to do? I have enclosed 1 photo- can enclose more. Gets lots of sun. Underground sprinkler system installed end of May. Thanks!!!
Sorry to hear about your browning cedars. Could the installation of your sprinkler system at the end of May caused damage to the roots of the cedar in question?
