The young trees sprinting symbolizes

In My Mother at Sixty-six, the “young trees sprinting” symbolize the energy, vitality, and youth that contrast sharply with the poet’s mother’s frailty. As the poet drives past them, the trees appear to be full of life, moving swiftly and effortlessly. This image highlights the poet’s awareness of the difference between the youthful vigor of nature and her mother’s aging, symbolizing the passage of time. The “sprinting” trees evoke a sense of movement and life, reminding the poet of the inevitable march of time, while also intensifying her fear of losing her mother.
