Five Signs of Tree Disease That You Should be Able to Spot

We love our trees' ability to turn carbon dioxide into oxygen, giving us clean, fresh air. Trees also keep us cool in the summer, warm in the winter, and are pretty to look at. Additionally, a healthy tree can live for a hundred years or more. 

However, just like animals, trees also can catch diseases. That's why you should be aware of these five signs of tree disease. If you spot one or more of these signs, call our tree service contractors in Arvada, CO.

1. Brown, Yellow, or Wilting Leaves
   It’s perfectly natural for a tree’s leaves to turn brown, yellow, or start wilting during fall. However, if you notice these leaf changes during any other time of the year, it may indicate an issue. Yellow leaves mean a tree has a nutrient deficiency which eventually develops into brown and dead leaves. Other times, salt spray or winter salt removal also causes wilting or brown leaves or needles. 
2. Changes in Tree Bark
   Subtle changes in tree bark may be signs of tree disease. Fungus primarily targets infected trees with rotten, brittle wood that feels moist to touch and might be cracking or peeling. If left alone, tree bark fungus will infect the entire tree. 
3. Holes or Hollows
   Just like a few dead branches aren’t a problem, neither are occasional holes or hollows. Typically, these are just cosmetic issues that resolve on their own. Minor insect infections from caterpillars or beetles typically cause holes or hollows. However, fungal diseases can also cause holes and hollows, and homeowners should deal with them. Calling an expert arborist can help you decide if you need to do something about the insect infection or if it’s better to leave it alone. 
4. Dead, Decaying, or Dropping Tree Branches 
   Dead, decaying, or dropping tree branches might indicate a tree is getting older or suffering from a common tree disease. Decaying tree signs include branches with very little or no foliage and a tree that no longer sports fruits or flowers.  While you can’t stop a tree from aging, regular trimming and pruning can remove unwanted dead branches. Removing a tree’s dead branches improves its appearance while preventing other limbs from dying. 
5. Changes in the Soil Surrounding Your Tree
   The soil surrounding your tree may indicate a problem with your tree’s health. For example, cracked or parched earth means your tree isn’t getting enough water.  However, compressed or waterlogged soil could mean the ground isn’t sturdy enough to keep your tree in place. In this scenario, your tree might even start leaning to one side. A leaning tree is a safety hazard, especially during a rain or winter storm.
