Bur oaks have a medium growth rate and can reach hefty sizes of 90′- 80′ in its native habitats. They are tolerant trees with alkaline, salty, clay and compacted soils being little hindrance. The trunk has deeply furrowed bark on a single stem. Autumn colors displayed by the lobed leaves are an unspectacular yellow to brown.
With its weak wood and long horizontal limbs as it ages expect to see some storm damage from snow and wind load. This can be mitigated some with pruning, but generally bur oaks grow strong structure on their own. Directional pruning will be necessary over streets and walkways.
