That is if you are isolated in a rural setting or have a fenced garden.
Murray McMurray Hatchery - Weeder Geese
Just beware that make geese can be a little on the aggressive side. True story. Once upon a time my supervisor who owned both the farm and had geese got in a lot of hot water when the Gander decided to take a peck at his wife's back side while she was reaching into the truck to retrieve a bag of groceries
Geese will eat the weeds in a berry patch and drop fertilizer as they go.
