Answer 1

"The Doll in the Garden: A Ghost Story by Mary Downing Hahn
http://www.amazon.com/Doll-Garden-Ghost-Story/dp/0618873155/ref=sr_1_1/104-8412583-2845536?ie=UTF8&s=books&qid=1192137153&sr=1-1
"From Publishers Weekly
After the death of her father, Ashley and her mother move to a new town to start over. Ashley doesn't mind their small, second-floor apartment, but she takes an immediate dislike to grumpy Miss Cooper, the owner of the house. Fascinated by the tangled, overgrown rose garden in the back yard, Ashley and her new friend Kristi explore the neglected, forbidden area. When she and Kristi unearth an antique doll buried beneath one of the bushes, Ashley soon finds herself entangled in a ghostly past and its ties to the present. In evidence is Hahn's usual detail-oriented prose, which deftly sets the stage for intrigue"

Answer 2

I can only think of one book where there is a haunted garden and that is Toms Midnight Garden. It tells the story of a boy who is staying with his aunt and when the clock strikes 13, the house reverts to how it would have been in Victorian times and there is a beautiful garden outside.
