Quercus macrocarpa (Bur Oak)

Also known as Burr Oak, Savanna Oak, Overcup Oak, Prairie Oak.

Bur Oak is a large, stately deciduous tree with a wide, open crown. The acorns are the largest of all native oaks. Bur Oak is moderately fast growing and its strong wood makes its branches resistant to wind and ice damage. Its corky bark protects it from sunscald. Bur Oak develops large taproot and is drought-tolerant once established. It is also oak wilt resistant.

Bur Oaks are used by a wide range of wildlife, including mammals, songbirds, ground birds and insect eating birds. Acorns are also eaten by wildlife.

Planting Instructions: If the tree is buried too deep in the container, remove excess soil to uncover root collar. Loosen exterior roots gently. Place the tree in the hole so that the root collar sits a bit above the ground level since the soil will settle some. Backfill using soil that was dug out. Pack the loose soil with your hands to avoid air pockets. Add mulch keeping it at least 3-5 inches away from the tree trunk. Water deeply.
