Pin Oak in Maryland: Form, Function, and Fall Color
The Pin Oak (Quercus palustris) is a widely planted oak in Maryland, admired for its pyramidal form and deep green foliage that turns russet-red in fall. While visually appealing and fast-growing, Pin Oak requires thoughtful site placement and monitoring due to potential iron chlorosis and shallow root flare issues in urban soils.
Growth and Soil Preferences
Pin Oak grows 60 to 80 feet tall, with a strong central leader and characteristic lower limbs that angle downward. It prefers acidic, moist soils and full sun. Alkaline soils in urban areas may cause nutrient deficiencies, often visible as interveinal chlorosis.

Value and Vulnerabilities
Pin Oak acorns feed wildlife, while its symmetrical form adds visual balance to streetscapes and large lawns. However, the species is prone to girdling roots and basal decay if planted too deeply or improperly mulched.
Professional Tree Care for Longevity
Regular soil pH monitoring, air spading to expose root flare, and pruning to manage canopy density are key services that maintain Pin Oak health. Early identification of leaf discoloration and decline is essential.
