How can it be expressed in good English ?
Rudeness tramples down modesty's sprouts like cattle trample down the young shoots (or verdure ?).
Verdure is a very literary word; it is seldom if ever used in speech (I may have heard it used a handful of times in 60+ years - with an average of approximately once per decade ; in those cases it was used with irony or mock pomposity, or perhaps rhetorically in speeches about preserving the environment).
Cattle trample down greenery. What you eat (green vegetables) is (it's a mass noun, like 'sugar') greens, as in 'My mother used to say I should always eat my greens'.
