Tree sickness can be treated successfully be using systemic tree feeding, systematic deep root feeding, and tree injections. Tree service Fort Worth would like to help you spot problems and educate you on what to do.
OAK WILT
LIVE OAK : Keep in mind that the leafs on a tree are the best way to tell the health of a tree. Just like a person's skin, hair, and nails could be indicators that he or she is sick. In the same way the leafs on a tree are the best way to tell if there's a problem with the tree.
Live Oak trees have an oval shape leaf with veins in the middle of the leaf going from side to side. They almost look like a tree shape within the leaf itself. On a healthy live oak there should not be any discoloring within the leaf other than a solid green on one side and the lighter green color on the opposite side.
When inspecting your Live Oak keep this in mind, Live Oaks stay green through out the winter and don't start to shed until the end of that season going into the spring. At this point you will start seeing several live oak leafs start to turn brown and dying. The Live Oak will start look like its sick because all the other trees are in their spring time.
Please don't worry, this is very normal. Also remember that not all Live Oaks shed at the exact time so you might have several Live Oak trees shed weeks apart. This is also very common and you should not be alarmed.
What you should be alarmed about is leafs starting to turn a yellowy, brown color from the center of the leaf itself any time from May - December. This could be a dead give away that the tree could have a problem with disease. At this point, you should call a professional Arborist so lab work can be done on your tree and analyze the problem.
Remember that Live Oaks are very social trees, what we mean by this is that if you have other trees close to them especially other Live Oaks, they will inter-tangle their roots together with the others. This could be a major problem because if one gets effect with Oak Wilt all your trees could be infected with the disease. Diagnosis and treatment is essential at this point.
Oak Wilt on Live Oaks will normally kill the tree with in 1-6 months of being infected!

RED OAK: Is very referent from Live Oak trees and spotting issues is a little more complex. Here are some of the noticeable signs of trouble with the tree. During the spring time, you will see that the leafs don't bloom like other trees. They will wilt, not open and turn a brown or a pale green color and wither away. This normally starts on one side of the tree and soon after, the whole tree is effected. If a Red Oak does not bloom normally, you have a major problem and need to call an Arborist quickly to diagnose. If the tree has Oak wilt it will die in a matter of three to four weeks.
If you notice during any season that the tree has developed fungal spores on the bark, you definitely have a problem and it could very well be Oak wilt. You will have to inspect your trees frequently, in Red Oaks, sometimes the Fungal is hidden behind the bark so a close inspection will be needed. Normally fungal spores will have a fruity smell to them.

INFECTION and Contamination of oak wilt
contamination OF OAK WILT IN LIVE OAK TREES
In Live Oaks with Oak Wilt spreads the disease through their root system. Live Oaks normally grow in a group called Oakwoods and their root system inter-tangles with one another. When one tree get effected its only a matter of time before the rest of the trees get infected. This is why it's important to treat the infected tree at first sight of the disease, before infestation takes over the whole plantation and your loss is huge. Remember any tree looking brown and not responding to its season correctly will have to be evaluated immediately.
CONTAMINATION OF OAK WILT IN RED OAK TREES

The difference between contamination of the Red Oaks vs. Live Oaks trees is very different read the following.
Red Oaks: transmit oak wilt through the land contamination and normally will need a host to carry the disease to another tree. It has been proven that when a red oak produces fungal spores, they let off a fruity scent that attracts all kinds of bugs and insects. One of these bugs is the sap-feeding nitidulid beetles in the picture above.
If this beetle gets infected and moves on to another tree that has bark missing in a particular area, it will contaminate the other tree with the fungal. That's why pruning trees in late winter is best to give the tree time to seal and dry in the cut areas before spring and summer when these beetles are present.
Another way Oak Wilt is transmitted is through man by cutting of contaminated wood and placing it in areas where other red oak exist. When Cutting wood inspect it first before transporting it to your desired location.

Root Rots: another texas tree disease
This disease is caused by fungi and water molds that decay the root trunk tissue. This is caused by a wound to the tree at some point that protruded into its tissue core.
Bacterial leaf scorch: ANOTHER TEXAS TREE DISEASE
Bacterial leaf scorch (bacterium Xylella fastidiosa) is caused when the summer time comes and the tree is under stress from the heat. This bacteria lives in the water xylem of the tree and normally is transmitted by insects that feed off of the Xylem. The tree is stressed over time and die back starts to take place until the tree completely shuts down and dies. The scorch on the leafs look like a yellowy brown and at times can be mistaken as Oak Wilt.
