Answer:
Mary and Dickon are trying to fix up the garden to make it beautiful again.
Explanation: At the turn of the 20th century, Mary Lennox is a neglected and unloved 10-year-old girl, born in British India to wealthy British parents who never wanted her and made an effort to ignore her. She is cared for primarily by native servants, who allow her to become spoilt, demanding and self-centred. After a cholera epidemic kills Mary's parents, the few surviving servants flee the house without Mary.
She is discovered by British soldiers who place her in the temporary care of an English clergyman, whose children taunt her by calling her "Mistress Mary, quite contrary". She is soon sent to England to live with her uncle, Archibald Craven, whom her father's sister Lilias married. He lives on the Yorkshire Moors in a large English country house, Misselthwaite Manor. When escorted to Misselthwaite by the housekeeper Mrs Medlock, she discovers Lilias Craven is dead and that Mr Craven is a hunchback.
At first, Mary is as sour and rude as ever. She dislikes her new home, the people living in it and, most of all, the bleak moor on which it sits. Over time, she becomes less temperamental and befriends her maid, Martha Sowerby, who tells Mary about Lilias, who would spend hours in a private walled garden growing roses. Lilias Craven died after an accident in the garden ten years prior, and the devastated Archibald locked the garden and buried the key.
