There are several types of fungi that can cause one side of a tree to look dead. The most prevalent are phytophthora root rot and verticillium wilt. These are pathogens that live in the soil and affect the movement of water and nutrients. These fungi can cause a decline or even the death of the tree.
“Half dead,” regarding a tree, means that the tree is unwell or dying on one side. It's kind of deceptive to call a tree half-dead. These trees are in partially poor condition. “Partial” means they can still grow. If a tree can grow, it's technically not dead.
So can a half-dead tree be saved? It depends. In many cases, the answer is a resounding YES! And in other cases, the answer is NO — with the possibility of renewed life from root systems that still have the capacity to sustain tree life.
If it has completely dead branches, you can have them removed if they pose a threat, but it's oak, so they won't fall quickly. But don't have it pruned. Pruning trees always, and I am not being hyperbolic here, shorten a tree's lifespan. Trees know better what they need than us, so we should let them do their thing.
An important note about branches: a single dead branch or twig does not mean the entire tree is dead. All large trees will have some dead branches; it's part of their life cycle. However, if a tree has multiple large, dead branches, something could be wrong with the tree.

In forest ecology, a snag refers to a standing dead or dying tree, often missing a top or most of the smaller branches.
While it is possible to revive sick or dying trees, bringing dead trees back to life is typically not feasible. There are several reasons to remove a dead tree — but how exactly can one tell if a tree is dead, sick, or healthy?
If you have a tree that's broken in half, you might ask yourself, “Can it be saved?” The good news is that the answer is often yes. If your tree's damage is not fatal, and if there is enough of it left healthy, you can likely save your tree.
There are two stages of killing a tree. First, the tree should be pulled out entirely. Its roots are to be exposed to the sun and the air. Secondly, the roots are to be scorched in the sun.
An effective watering method is to place a sprinkler directly below the tree so the spray reaches the entire root system. Use an old can to measure when the sprinkler has produced about two inches of water. When the water hits this line, turn off the sprinkler.
There are a few things you can look for to tell if your oak tree is dying. One is if the leaves start turning brown and falling off the tree. Another is if the bark is starting to peel or crack. If the tree is leaning to one side, it can also signify that it is dying.
Look for wilting, yellowing, and premature leaf drop. Cankers may form at the base of the trunk, accompanied by a distinct mushroom growth near the tree base, particularly during wet conditions. Caused by various Armillaria species, this is an opportunistic disease because the fungus targets weakened or stressed trees.
While only a small part of your tree may die, experts suggest you prune 30% of the entire tree. This method allows your tree to send its nutrients and water to much less of itself and allows the tree to heal.
The dieback disease affects leaves, twigs and the inflorescence of neem trees of all ages and it causes almost 100% loss of fruit production in severely infected trees. The dieback is a fungal disease but the neem trees are sometimes hit by insect infestation and the combination of both increases its impact.
Standing dead trees, also known as snags, are extremely valuable to wildlife and even some pollinators.
Re-fertilize all around the tree, especially the ground directly underneath the branches, to support those stressed roots. Next, apply fresh mulch in a donut shape around the base of the tree about one foot in distance away from it. This helps to prevent new diseases from taking advantage of weakened trees.
The only way to save a tree that is only partially alive is to remove the factor that is causing its demise. If it's due to a lack of water, then giving the tree some to drink should be enough to get it back on its feet.
Trimming oak trees is essential to encourage healthy growth. Removing dead, diseased, or weak branches prevents pests and diseases from spreading throughout the tree. Prevents Disease: Proper trimming improves air circulation, reducing the risk of disease.
Sometimes, it is hard to decide to remove dead wood from a tree, especially if you do not know how to identify it and unsure if pruning will help the tree or not. Cutting off dead branches is good in most cases, but you still need to know how to do it safely. Dead branches do not necessarily mean a dead tree.
Dead or dying branches pose a considerable health risk to the tree and should be removed when detected. When a branch dies, there is no sap running through it, thus minimizing the risk of oozing sap after its removal.
Determining if a tree is dead in the winter is a little bit more difficult because dormant trees can look just like a dead tree. One thing you can look for however is if the tree has buds on the branches. Even in the winter time a tree should show signs of buds.
