Oak, Sawtooth

Sawtooth Oak (Quercus acutissima)

Sawtooth oak is an Asian oak with narrow, sharply toothed leaves and a broad shade canopy. Its acorns sit in conspicuously bristly cups, and mature trees can drop a substantial crop of nuts and cups.

Key Characteristics

Acorns and Garden Management

This species has been widely planted for wildlife food, but crops and the age at first bearing vary. Do not rely on a guaranteed five-to-seven-year crop. Allow for acorn litter, fallen cups, and volunteer seedlings around an established tree.

Important Ecological Context

Sawtooth oak is not native to North America and has escaped into eastern U.S. forests, including North Carolina. It should not be presented as a native restoration tree. For a habitat or restoration planting, consider native options such as Chinkapin Oak on well-drained ground or Overcup Oak on seasonally wet ground.

Room for the Mature Tree

Choose sun and acidic, moist, well-drained soil. Keep it away from confined paved spaces, and monitor nearby natural areas for seedlings. Native oaks provide a more appropriate starting point when the goal is rebuilding a local woodland community.

Product Details

• Acorns: Bitter nuts in bristly cups; crops, litter, and seedling spread need consideration.

Planting and Ongoing Care

Water the root ball before planting, address circling roots, and mulch clear of the trunk or crown. Water through dry spells during establishment and protect young growth from browsing and equipment damage.
