Turnip

White turnips are a type of flora, having appeared in every game to date. They can be sold on the "Stalk Market" through Tom Nook which is the Animal Crossing version of the Stock Market. They can be bought from Joan on Sundays, before 12 p.m. There are glitches and manipulations in the Animal Crossing series that keep turnips from rotting over longer periods of time.

Buying
White turnips have appeared in every Animal Crossing series game, and can also be bought from Joan on Sundays. They are a more risky investment than red turnips because the price they sell for isn't fixed. Joan has an asking price which is generally around 90-100 Bells per turnip. They can be bought by the player as many times as they like in bunches of ten.

Selling
Nook will buy white turnips from Monday to Saturday. He has two prices a day, one before midday and one afterwards. The aim is to sell the white turnips for more than what was originally paid for. White turnips will become spoiled and worthless at 6 AM on the following Sunday morning.

Normally the price is low, such as 60 or 80 Bells, but the price can peak to over 200 Bells and can sometimes reach to over 1,000 Bells each. Prices are somewhat random, but tend to rise Monday through Wednesday then usually drop Thursday through Saturday, though it has been known to have a last minute increase. Time travelling can have effects on the price of the turnips if the game's time and the system's time are too different, like with Joan and the selling of red turnip Seeds. However, using the system's internal clock to travel will not create this effect, as with the red turnips.

Spoiled white turnips can be placed outside to attract ants and flies.

Tricks
''Some known turnip tricks are listed below. These tricks address any outcomes from Time Travelling or failing to water the turnips.''

Time Travelling Consequence
Time Travel, which is when the player changes the time in Animal Crossing, has an effect on Joan selling her turnips. She will say she is out of stock which is seen as a punishment for if the player attempts to time travel. However, a glitch can be used to fix this. To fix this glitch, the main Wii/DS time must be changed forwards a minute, resynchronizing the game time with the console time. However, to buy Joan's turnips will require waiting a week until she visits again.

Another way to avoid this is by changing the console time. Changing the console's time changes the game's time, but not the other way around so there are no consequences.

Table Trick
To keep white turnips from rotting, placing them on a table inside the player's house can prevent them from rotting. First drop a tool in front of the table, then drop the turnip which should land on the table. The table trick does not work in Animal Crossing: City Folk.

Glitch
In, if the player has turnips in their inventory and they travel on the train, they will turn spoiled when getting off at the destination.
