Speak with Tortimer during the Flower Fest for free flowers.
To get free flowers and win the Flower Fest, take the flowers from your neighbor's houses. To get more, go to your neighbors' houses every day. Do this every day and you’ll win the Flower Fest.
After picking a flower, go to your pockets and drag the flower to your player. If your player is a girl, she will put it in her hair. If you pick a Dandelion, drag it to your player so they hold it in their hand. Then press A and your player will blow the Dandelion. This only works with the Dandelion puffs. If you drag a Rose to your player, they will hold it in their mouth. You can put Clovers into your girl player's hair.
