Players start with a 3x3 grid of land. Each square of the grid can hold one item. Players can expand their garden b 1 row & column at a time by purchasing a Garden Expansion from the store.
You start out with a 3x3 garden- buying an Expansion makes it 4x4, then 5x5, then 6x6. When you expand past 6x6, you can buy a New Garden, which then gives you a second 3x3 plot. You'll move between garden plots using the trowel arrows that will appear on the main page.
