Wembley groundsman Tony Stones worked with royal household gardeners to create the 110 yards x 65 yards (100m x 60m) pitch in the 39-acre (16 hectares) garden.
The lawn was seeded in parts to repair wear and tear following a busy summer which saw the grounds host garden parties and the Coronation Festival.
The pitch started to be marked out last month.
Since then the royal gardeners have been mowing the ground three times a week and creating a criss-cross pattern in the turf to mirror the Wembley stadium pitch.
