Utah and Oak Trees

Firstly, we wanted to clear up any confusion regarding bur oak trees in Utah. Tree enthusiasts with a keen eye will note that many oak types don’t tend to do well in most parts of Utah due to improper soil and climate conditions – but the bur oak is one major exception.

The bur oak, unlike other oaks, is well-adapted to many areas in Utah. There still might be some limited areas where it will struggle based on conditions, but it will generally do fine throughout the majority of the state.

Bur Oak Blight Basics

One of the only common conditions that might affect a bur oak tree is bur oak blight, which is a fungal disease that only was discovered in the 1990s. It’s most common in midwestern states across the US.

When bur oaks are infected with this condition, it begins slowly but becomes more and more severe with time, eventually leading to death if untreated. In many cases, the symptoms will begin in spring but will not be noticeable until August or even later.

How it Develops

Here are the general buildup steps of bur oak blight in bur oak trees:

  • During spring, leaf stalks release spores that have developed over the previous fall and winter.
  • Rain and wind move these spores onto other leaves, spreading the infection.
  • Leaves may look healthy all the way up until late July or even August or September.
  • Dead leaves and leaf stalks begin to form black pustules, staying on trees and kicking off the cycle again the following year.
  • Infections can take place at any point through the growing season.

In part two of our series, we’ll go over how to spot, prevent and remove bur oak blight from trees. To learn more about this or any of our arborist and tree health services, speak to the staff at Affordable Tree Care today.
