When you tap on the Friends Feature icon, a window will appear. On the top left, you will see the “Friends” section. Every 23 hours, this will refresh, and you will be able to send gifts to 5 of your friends. When you are able to send a gift to a friend, an icon of a red gift box with yellow stripes will appear next to that friend’s garden name. Tap this icon, and you can give a gift. After you send a gift, a green tick will appear next to their name as confirmation.
