December 5, 2024 – Oaks are initially divided into two groups. With only 4-5 exceptions, white oaks have leaves with rounded lobes, and red oaks which have pointed lobes. Within the red oak family, a relatively unknown species called Shumard oak (Quercus shumardii Buckl).
Shumard oaks are a member of the southern red oak family, and are one of the largest members of that group. They accept virtually all soil types in our area, and very few insects attack it. Life expectancy is one hundred years plus, and it’s known to live to 400+ years. Neil Sperry, a nationally known horticulturalist was noted that if he could only have one tree in his yard, it would be a Shumard oak (SO)!
SOs normally reach up to 115’ with a diameter of 39” and a crown of 60’, although under ideal conditions can reach 200’ tall, 60” in diameter, and a crown of 90’. The bole or trunk is vertically straight. They can survive flooding for up to six weeks a year and have a deeply rooted buttress (wide roots on all sides) to provide support under wet conditions.
Leaves are typically large (up to 8”) with 5-9 lobes ending in pointed tips. Leaves provide browsing food for deer. They turn red in late fall (November & December) and may have some yellows mixed in. Acorns are normally 1” in diameter and attractive to deer, turkey, quail, squirrels, water fowl and other animals. They take anywhere from 1.5 to 3 years to develop and don’t appear for at least the tree’s first 25 years. SOs tolerate both acidic and alkali soils and are drought resistant.
SOs make great shade trees but also have considerable commercial value. SO lumber is considered better than other red oaks and used in flooring, furniture, paneling, cabinets, trim, and molding.
