Life span of our mature trees

Asked March 20, 2019, 5:10 PM EDT

What is the life span of a silver maple? A locust tree? We have one of each and are guessing they are at least 60 years old. (If you make it public, please don't share my e mail with the public). Thank you Ben Hennepin County

Thank you for the question. The lifespan of any tree is difficult to predict and depends on many factors. Silver maple can live for many years, up to 130, if conditions are right. In an urban environment, the life expectancy is probably much shorter. Learn more here: https://plants.usda.gov/plantguide/pdf/pg_acsa2.pdf

Honeylocust can live up to 150 years under ideal conditions. Again, life expectancy is shorter under less than ideal conditions. Read more: https://www3.northern.edu/natsource/TREESA1/Honeyl1.htm

Thank you for contacting Extension.
