Try this quick test: Using your fingertip or a pocket knife, scratch one of the tree's twigs. If it's moist and green underneath, that portion of the tree is alive. If it's brown and brittle, use this step-by-step process to inspect the tree: Scratch a couple more twigs to see if any are fresh green underneath.
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.
It's usually not possible to revive a completely dead tree. Trees are complex organisms, and once they've reached the point of being entirely lifeless, there is little hope for a return to vitality. However, reviving a half-dead tree is possible with careful pruning, proper care, and expert guidance.
If we look further up in the canopy, we see that there's nothing green up there, no pine needles, no leaves, and even the branches are looking stubby, and that is because they are falling apart as they rot.
Check the tree's bark, trunk, and roots for signs or life (or death). Healthy trees will shed and replace their dense bark, while dying trees will struggle to regenerate bark and could even lose their bark completely. Trees in poor health might have dangerous cavities, cracks, or fungi on the trunk.

Saving a dying tree is possible, but it takes experience, care, and foresight. There are many environmental factors that can cause a tree's health to decline, the most common offenders being insect damage and disease.
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.
Look for signs such as extensive dead or decaying branches, significant lean, visible cracks or wounds in the trunk, and root damage. If the tree poses a safety hazard due to its proximity to structures, power lines, or roads, it might need to be removed.
But a tree care professional or arborist is going to know more about why a tree or shrub might be sick or dying, and they will be educated about the proper way to handle the problem.
Other symptoms of transplant shock appear as wilting leaves (especially on recent transplants), yellowing, and leaf rolling or curling.
In nature, a dead tree is a vital part of the ecosystem, so it can stand for as long as a day or two to one or more years before falling.
Dead trees and trees in shock can look deceivingly similar, but there's an easy way to tell the difference. Pick a random twig on the tree and scratch it with your finger or a pocket knife. Do the same for a few other twigs throughout the tree. If they're all bright green and moist underneath, viola!
In summary, while it's possible to save a dying tree, the likelihood depends on the root cause and how quickly you act. Early detection and intervention are key to giving your tree the best chance at recovery.
The tree has a structural issue, restricted root system or poor soil that prevents it from gaining the nutrients it needs to grow properly. Sometimes trees with thin bark or trees planted in the wrong hardiness zone can have wood and buds that become damaged and don't leaf out due to extreme temperatures.
You can usually revive a half-dead tree, but a tree that's 100% dead should be removed. If you've been wondering, “can you bring a dead tree back to life?” an arborist's professional opinion will always come in handy.
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.
Inspecting Buds
One of the easiest ways to tell if a tree is dead or dormant is to inspect the buds. Even during dormancy, new buds will grow from a tree's crown, which is a clear sign that the tree is still alive. A dead tree will not grow new buds, or have any buds currently growing on any part of the tree.
Peeling or loose bark or cracks in the tree around the tree's root collar. Swelling, soft or decaying wood, or small holes in the tree trunk. Dead, dying, or drooping branches in the canopy. Wilting, discolored, or damaged leaves.
A Dead Tree Can Damage Your Home
Not only can the tree fall over and damage your home or car, but the limbs can also fall off and cause serious injury. In addition, a dead tree is a major fire hazard. If it catches on fire, it could easily spread to your home or other trees in the area.
Healthy trees that have lost less than half of their leaves will usually survive. Healthy trees losing more than half the leaves can survive defoliation 2-3 years in a row.
