Obviously the tree cannot describe the problem to me. The history of the tree is very important. How long has the problem been going on? What were the early symptoms? Has there been any construction , excavation, or chemical treatments in the area? Careful diagnosis of tree problems requires a careful examination of possibilities by following a few important steps.
(1) It is important to accurately identify the specie. Knowing the identity of the plant can quickly limit the number of suspected causes.
(2) Look for a pattern of abnormality. An Arborist must first know what is normal for the Tree, for example when the Oak tree sheds its inner branches and they drop off then he will know that this is normal for Oaks to do this. We will also look at similar trees close by to compare with the specimen we are examining.
(3) Carefully examine the site. This could explain a lot if the grade has been changed has there been any changes to the soil , has there been any sprinkler lines added or if you live up north any de- icing salts added.
In Florida and particularly Pinellas and Pasco counties there is an outbreak at this time of a particular little pest called the Asian Scale and it is affecting mostly Sago palms, This little pest is small and white and it survives on feeding on the juice from the sago's.

Beechnut tree was called out just a few weeks ago to diagnose some dead Italian Cypress as I drove to the site I noticed the customers yard was a stone yard. I asked him how he kept the weeds out of his stones and he told me that he uses Round up. I informed him that the weed killer could have killed the Cypress tree's .
Another pest that I think you should know about especially if you have Pine Trees on your property This pest is called the Ipps Pine bark beetle it is very prevalent throughout Pasco and Pinellas counties it is a pest that is attracted to the smell the Pine tree puts off when it is stressed out. I cannot tell you how many pines I have removed due to this little pest. Here is a few pictures to inform you and show you what to look for. These pests start chewing on the pine and make small little blobs on the side of the trunk called pitch tubes and look like this.
