Young twigs will bend but not old trees.

This saying is a traditional Dutch proverb, part of a wider European stock of folk wisdom that contrasts the pliability of youth with the rigidity of age. It is typically invoked in discussions of education, childrearing, and moral formation: children (like young shoots) can be guided, trained, and shaped, whereas adults (like mature trees) are far harder to change in habits or character. In Dutch and neighboring cultures, plant-and-growth metaphors are common in proverbial speech, reflecting agrarian experience and the observation that early training has lasting effects. The proverb is often used pragmatically—sometimes approvingly, sometimes as a caution—when urging early instruction or warning against expecting deep reform late in life.

The proverb argues that malleability belongs chiefly to the early stages of life. “Young twigs” suggests new growth that can be bent into a desired shape without breaking; “old trees” suggests established form, hardened fiber, and deep roots—structures resistant to alteration. As a piece of moral psychology, it emphasizes habit-formation: repeated actions and beliefs become ingrained over time, making later change costly or unlikely. It can support humane investment in early education and socialization, but it can also be read critically as fatalistic about adult transformation. Its enduring appeal lies in its vivid natural image and its practical counsel about timing: influence is most effective before patterns set.
