Answer: New growth is stricken with the blight before it has the chance to mature.
Explanation:
American Chestnut trees can indeed regrow from their roots but due to the devastating effect of the chestnut blight, they have been unable to do this since the blight spread across the country.
The blight was introduced when Chinese chestnut trees were imported into the U.S. in the 20th century.
