Red Oaks with Fungus

Asked September 27, 2017, 3:54 PM EDT

Help! The past few years, we have planted red oaks to replace pin oaks in our neighborhood. The pin oaks were planted by the developer 50 years ago and have declined/died due to the stress of being street trees with not much room for root growth, heat from the pavement, and salt from snow removal. Many of the newer red oaks are now showing signs of a fungus, which we are told is systemic. So, as we contemplate our fall planting, is there another oak we can consider - i.e., white oak? Our landscaper says no willow oaks as the leaves are difficult to take up during the fall clean up. Maybe we should just go back to pin oaks which were installed by the developer 50 years ago? So far, they've been OK with no insect or drought damage, no blight. Thanks for your advice!

We would recommend a member of the white oak family, as they are more resistant to bacterial leaf scorch and drought. Pin oaks and red oaks in general are showing a lot of bacterial leaf scorch problems.
