Main Disease. Oak wilt is caused by the fungus Ceratocystis fagacearum which develops in the outer sapwood of the tree. The infected tree reacts by developing tyloses and gums which subsequently restrict the flow of water and nutrients in affected vascular tissues with the result that the tree wilts and subsequently dies (French & Stienstra, 1980). Host Range.
Step 1. Plant the oak tree in a location that provides at least eight hours of direct sunlight, good air ventilation and nutrient-rich soil. The soil's nutrients are essential for the tree's development.tep 2. Test your soil's pH levels and match them to the specific oak tree selection. There are several different kinds of oak trees, including the Northern Red, Live, Southern Red, White and Willow, to name a few.
