"Let's Get Growing!"

"Let's Get Growing" is the main game mode where the player grows a variety of plants in a garden, ranging between flowers, fruits, and vegetable. Players initially start with only a few flowers, but are able to unlock more plants and garden areas after finishing complete flower cycles (from planting the seed to when the flower blooms). Like previous Mama games, for a plant to grow the player needs to complete a series of mini games; however instead of playing each stage consecutively, only one stage can be played at time. The next stage becomes available once the player completes another stage for a different plant, or the next time the player turns on their handheld device.

After completing a stage, the player's performance is evaluated with a numerical score out of 100, and awarded either a bronze, silver, or gold medal. After completing a full plant cycle the player's overall performance is evaluated, and given an averaged score out of 100 and a corresponding medal.

There are many different mini-games available, for example: planting seeds/saplings; watering plants; cutting off or removing weak/dead parts of plants; shooing away pests and rodents; harvesting produce; and making rainbows using a watering hose.

Players also have a "practice" option.

Multiplayer

In the "Let's Play Together" mode, Gardening Mama supports wireless multiplayer, along with "Download Play". During such a contest, players compete in individual minigames. Players can also exchange produce they have grown with the "Cute Treasure Chest" function.

Bonus sections

If a player completes a stage under a certain time they receive a "bonus sapling". For every three bonuses earned players receive an unlockable item, such as accessories for Mama, decorative gardening items, or extra items that can be used in the game.

There are two bonus sections: "Decorate the Garden!" and "Make it Fancy!"

In "Decorate the Garden", players can add decorative items they have unlocked to their garden, such as small flower pots and garden gnomes. The "Spruce Up Your Screen" menu can also be opened from here to change the appearance of various gardening tools and background items.

In "Make it Fancy", players can use unlocked clothing items to customize Mama's appearance. Various accessories, like glasses and earrings, can be added; Mama's clothing can also be changed.

Special fertilizers can also be unlocked via the bonus saplings, which allow growing unique plants that can be grown in an area called "Special Garden".
