The peaches here shown illustrate the possibility of remodeling an old peach orchard by grafting. This bunch of luscious fruit was borne on a cion only two years old, grafted on a tree that otherwise would have borne fruit of inferior quality or no fruit at all. There are thousands of abandoned peach orchards that might be rejuvenated by proper grafting.
