What does 'planting them close to each other' mean?
I am trying to unlock new seeds in the garden minigame by cross-breeding plants. The help says "You can cross-breed plants by planting them close to each other; new plants will grow in the empty tiles between them." What exactly does this mean? Should I plant seeds diagonally across from each other so new plants can grow in the spaces adjacent to both, or should I plant seeds right next to each other and expect new plants to grow in the space next to them?
