Description

Pin Oak is native to eastern and central USA and is one of the faster-growing red oaks. It has a more slender graceful appearance than some oaks. It tolerates wet feet and requires acidic soils but is adaptable to drier and urban conditions. Pin oak is shallow-rooted and easily transplanted. The crown is pyramidal to oval. Pin oak won’t begin producing acorns until around 20 years old.

The branching pattern is unique with the lowermost branches being angled sharply downward, the middle branches horizontal, and the upper branches ascending. Young trees and lower branches of older trees hold leaves throughout winter.

Pin oak is infrequently attacked by the common diseases of oaks. It is susceptible to iron chlorosis due to alkaline soils which cause yellow coloration in the leaves through the summer months and can eventually kill the tree. 

Pests include gypsy moth (Lymantria dispar), obscure scale (Melanaspis obscura), oak leaftier (Croesia semipurpurana), pin oak sawfly (Caliroa lineata), scarlet oak sawfly (C. quercuscoccineae), forest tent caterpillar (Malacosoma disstria), leaf roller (Argyrotaenia quercifoliana), horned oak gall wasp (Callirhytis cornigera), and gouty oak gall wasp (C. quercuspunctata).

Diseases include oak wilt (Ceratocytis fagacearum), oak leaf blister (Taphrina caerulescens), pin oak blight (Endothia gyrosa), and Dothiorella canker (Dothiorella quercina).
