What are some symbolic examples of Water and Greenery/vegetation found in the Crime and Punishment?

Water is to Dostoevsky a symbol of rebirth and regeneration. It is regarded as such by the positive characters, for whom it is an accompaniment and an indication of the life-giving forces in the world. By the same token, the significance of water may be the opposite to negative characters. Water holds the terror of death for the corrupt Svidrigaylov, who confirms his depravity by thinking: "Never in my life could I stand water, not even on a landscape painting." Water, instead of being an instrument of life, becomes for him a hateful, avenging menace during the last hours of his life....

In contrast to the dusty, hot, stifling, and crowded city, a fitting setting for Raskolnikov's oppressive and murderous thoughts, we find, for example, "the greenness and the freshness" of the Petersburg islands.... The natural surroundings reawakened in him the feelings of his youth, through which he came close to avoiding his crime and to finding regeneration without having to pass through the cycle of crime and punishment....

By the same token, vegetation exercised the opposite effect on Svidrigaylov: it repelled him. In the inn on the night of his suicide, when he heard the leaves in the garden under his window, he thought, "How I hate the noise of trees at night in a storm and in darkness." Whereas Raskolnikov received a healthy warning during his short sleep "under a bush," Svidrigaylov uses the sordid setting of an amusement park which "had one spindly three-year-old Christmas tree and three small bushes" merely for vain distraction on the eve of his suicide, and contemplates killing himself under "a large bush drenched with rain." In him all positive elements had been rubbed out or transformed into evil.
