In fact, gardens can be seen as representing the female sexuality, and they are dangerous places because they are where virginity is compromised. This can be seen when Claudio convinces Don Pedro to win him Hero's heart, a scene that takes place in a garden. In this act, Beatrice will be tricked into loving Benedick by what she overhears in an orchard. Indeed, Hero's reputation, and also Claudio's perception of her virginity, is lost when Claudio and Don Pedro stand in the orchard and watch Borachio woo Margaret. The only way to clear up the confusion inherent in the play is to write everything down.
Writing becomes a way of clarifying and clearing up the mistakes.
This is the first point in the play where writing appears. It will later be used by Benedick and Beatrice, the Sexton, and Claudio who will write the epitaph to Hero.
