Tree disease can show up in many forms so be sure to look for signs. One thing to pay attention to is if the ground heaving upwards, there are signs of decay, signs of fungi like mushrooms, and severed roots. Try looking around the tree’s root collar, aka the area of the trunk right above the soil. See if there are any slits in the tree, peeling or loose bark, and cracks. With the rest of the trunk see if there are any holes, cavities, swelling, and soft or decaying wood. For the canopy see if the branches are hanging low with minimal leaves or are lacking bark. If you see weak v-shaped branch unions where two branches have grown together this can be an oddity as are leaning limbs or branches. See if there are any dead sections of bark on limbs and branches that are otherwise known as cankers. If there are any leaf problems like holes, spots, deformed leaves, or odd colors this can also point to tree disease. Finally, check to see if there are excessively thick or dense canopies that can easily break.
