Life Span Of St. Augustine Lawns

Q: Recently I was told that St. Augustine lawns have a natural life span of less than fifteen years. My own experience refutes this.

A: I agree with you! My own St. Augustine lawn has been here for twenty years. But in your part of Florida, stressors such as sandy soil, drought, chinch bugs, and take-all root rot could mean that most St. Augustine lawns give up and have to be replaced after approximately fifteen years
