Description

Sawtooth Oak is a medium-sized tree from Asia that is considered invasive in some states. It grows up to 60 feet tall and wide with and dense, wide-spreading, rounded crown at maturity. It prefers acidic, humusy, well-drained moist soils but is adaptable to a variety of soil types. It can produce acorns as young as 10 years of age and acorns are produced profusely on mature trees. 

Use as a shade tree for large lawns or parks. Flowers and acorns can be messy

Consider planting native oak trees instead.

Insects, Diseases and Other Plant Problems: Chlorosis (yellowing of the leaves) is common in neutral to alkaline soils, and can severely damage this tree. Potential insect pests include scale, oak skeletonizer, leaf miner, galls, oak lace bugs, borers, caterpillars and nut weevils.
