Well, it could be as simple as having a lemon - scented charm that repels Dementors. For example, a character could discover this charm in an old, forgotten book in the Hogwarts library. The smell of lemon might be associated with a powerful positive emotion that Dementors can't stand.
A lemon - themed element could be incorporated through a magical lemon tree. In the story, this tree grows in a secret part of the Hogwarts grounds. The fruits of this tree have the ability to create a protective shield against Dementors when crushed and spread around.

This could then lead to a series of events where they have to protect the tree from dark forces who want to use its power for evil.
