Fire Blight Treatment
Fire Blight is spreading like “wildfire” after two years with warm, wet springs.
Effective Fire Blight Treatment
There is a Fire Blight epidemic in the Front Range affecting Apple, Crabapple, and Pear trees that has dramatically increased every year since 2013. Our Master Arborist says, “It is uncommon for me to go to a property and not find Fire Blight on the Apple and Crabapple trees.” DLC Arbor is a leader in new and more effective approaches to Fire Blight.
We base our treatments on years of experience, the pathology of the disease and tree biology. Homeowners with Apple or Pear trees should us to discuss your treatment options. Homeowners who need an appointment, please fill out the tree service request form at the bottom of this page or give us a call at 303-378-8000.
Fire Blight Disease
Fire Blight is a bacteria that attacks Pome Fruit trees such as Apple, Crabapple, Pear, Hawthorn, and European Mountain Ash. Cherry, Plum, Peach, and other Stone Fruit trees are immune. Denver’s unusually warm and wet springs, coupled with early summer weather makes conditions perfect for bacteria to thrive and spread. Symptoms include:
- Branch tips bending into a “shepherd’s crook”
- Brown leaves
- Black bark or cankers
DLC Arbor treats Fire Blight by using a combination of trunk-injected antibiotics, low-nitrogen fertilizers, and sanitation pruning. DLC Arbor starts treatment as long as there are still leaves on the tree. When more than 40 percent of the tree is infected, we recommend tree removal.
