Since it will be a new garden, first check that no electricity wiring or gas lines exist. A double dug raised bed type garden is always nice if you intend to raise a garden every year. You can border the raised beds with lumber or concrete blocks or any other solid material. Cultivate deep, as plants need the extra depth for healthy roots and a bountiful crop. Put down pea gravel for the walkways and you won't have as many weeds. The beds should be as wide as you can reach without stepping into the bed. Raise the level of the beds at least 12" to help your back . In the long run raised beds are the way to go IF YOU HAVE THE ROOM.
