According to many, this is definitely not the best time to trim your trees in Austin because of Oak Wilt.
TexasOakWilt.org says that Oak Wilt, caused by the fungus Ceratocystis fagacearum, is the most destructive disease affecting live oaks and red oaks in Central Texas.
Oak wilt is commonly spread to other oak trees in two ways – long distances with the aid of certain beetles or locally through common or grafted roots, according to the Texas Forest Service.
Experts encourage that trees should not be pruned between February and June and the only reason people should prune trees within this time frame is to accommodate public safety concerns, clear limbs from utility lines, repair storm damage, eliminate rubbing limbs on buildings and remove dead branches.
Common indicators that your tree is infected include wilting leaves, discoloration of leaves, dropping leaves and tree death. Most trees die between one to six months of initial appearance of symptoms.
The Oak Wilt problem is so bad in our area that the West Lake Hills and Rollingwood city councils are considering options to protect their cities’ oak trees from this disease. To read more about what these city governments are doing about Oak Wilt, go to Community Impact Newspaper.
