Aesculus hippocastanum: Horsechestnut1 - Chestnut Tree Powdery Mildew

Edward F. Gilman and Dennis G. Watson2

Introduction
Horsechestnut can grow 90 or 100 feet tall, but is often 50 to 75 feet in the landscape with a spread of 40 to 50 feet. The trunk grows to three feet thick and is covered with dark, somewhat exfoliating bark. The prominent white flowers, occurring in panicles at the branch tips, are the main ornamental feature of Horsechestnut. The large brown nuts covered with spiny husks fall and can dent cars and create a hazard on hard surfaces as people roll on the golfball-sized fruit.
