Once a dominant species in eastern North American forests, the American chestnut was decimated by the chestnut blight, a fungal disease introduced in the early 20th century.
While resistant varieties are being developed, planting new American chestnuts can be challenging due to the ongoing threat of blight. They prefer well-drained soils.
