The operative root fact is natural root grafting with nearby red-group oaks, which is how oak wilt travels underground — managing a diseased tree can mean trenching or a root barrier between it and its neighbors, not just removing the infected stem. Otherwise the root plate is reasonably deep and it tolerates both compacted clay and periodic wet feet better than most oaks.
Roughly 50–60 ft in the open with a broad rounded crown, taller and narrower when forest-grown, and it comfortably exceeds 100 years. Mid-to-upper removal bracket — smaller than a mature bur or white oak, but the wood is dense and heavy for its size.
