Preventing Oak Wilt and Other Tree Diseases

As a property owner, it is important to take up the responsibility of keeping your trees free of diseases. Although many people are unaware, tree diseases, like the common oak wilt, are often spread by unsuspecting tree trimmers or contractors, which leads to the damage of other trees on your property by proximity. Because of this, it is essential that landowners and contractors alike take action to prevent these diseases from spreading. It is necessary to be educated and informed about the signs of healthy and diseased trees.

Common signs of healthy trees:

  • No wilting
  • Correct color and shape for the season
  • Evidence of tree growth
  • No dead branches
  • Little to no loose bark

Some common signs of oak wilt are:

  • Browning on the outer edges of the leaf that spreads to the mid-vein
  • Dieback (branch dies from the tip of the leaves toward the roots) progressing from the top of the tree down  
  • Leaves wilting in the spring or summer
  • Fungal spore mats forming on bark

Other common tree diseases to watch for:

  • Root Rot – usually resulting from poor drainage, a condition of the rotting of the tree’s roots
  • Fire Blight – causing dieback in the tree, infected leaves look as though they’ve been seared by fire
  • Sooty Mold – black fungus appearing on tree limbs and leaves

What to do when you identify a tree disease:

  • Talk to your landscaper or contractor about treating equipment between trimmings
  • Ask about contacting an arborist for more information about treatment
  • If necessary, consult the arborist about major removal services

Catching oak wilt and other tree diseases early on can potentially save you the hassle of removal at a later date and maintains the beauty of your property. Keep your trees safe from common diseases by checking them for signs year-round and communicating with your contractors and landscapers.
