Keeping Track
Keep track of the names of your various gardens or the nature of your gardens on a notepad. Note their age, what types of plants they contain and which pinatas you have attracted. Listing details, such as these, will help to distinguish valuable gardens from forgettable ones.
The Xbox Dashboard
Console gamers interested in deleting a garden can simply go to the Xbox System Dashboard. Select "Memory" then go to "Games." From there, you can choose which gardens you'd like to delete.
Windows
If you play Viva Pinata on the Windows Games platform in Windows XP, your save files are located in this directory: C:\Documents and Settings\username\Local Settings\Application Data\Saved Games\Microsoft Games\Viva Pinata\Saves. You can visit this location any time and delete a garden file. If you have Windows Vista or Windows 7, your save files are here: C:\Users\username\AppData\Local\Saved Games\Microsoft Games\Viva Pinata\Saves.
The Tower of Sour
Unless you want to delete all of your information for your gardens, don't delete the Tower of Sour file found among your other garden files regardless of which platform you're using to play the game. This is a general file that records income, inventory and other administrative statistics and, if deleted, will cause your gardens to become corrupted.
