This disease progresses quickly in red oaks like the pin oak, and can kill a tree in as little as one month. Pin oaks are particularly susceptible to oak wilt, a fungal infection which can be spread through beetles, root networks, and through firewood collected from infected trees. However, the condition is reversible if addressed early through the administration of supplemental iron. Left untreated, chlorosis will eventually kill the tree. This disease typically presents as yellowed leaves, and may progress further to curled brown leaves. This problem results from the alkalinity (high pH) of the clay-rich soils in the North Texas region, which over time prevent the absorption of iron. Fertilization – Maintaining adequate soil fertility helps prevent nutrient stress.The pin oak ( Quercus palustris) is a tree in the red oak family that is native to the eastern United States.Īccording to the Iowa State University Horticulture and Pest News, the most common affliction for pin oaks is chlorosis, a disease caused by an inability to absorb iron from the soil.
