Things You'll Need
Instructions
Find Joan wandering around town on Sunday between 6 a.m. and 12 p.m. She has a backpack full of turnips.
Buy the red turnip seeds from her. These will cost 1,000 bells. She may have already sold these seeds if you wait too long to talk to her.
Buy as many white turnips you can until you have no more bells or no more room in your house to store more. Each white turnip will cost between 90 and 110 bells.
Plant the red turnip seeds anywhere on the ground. Choose a location that is convenient to remember.
Water the red turnip seeds with the watering can every day. The seeds will die if you do not.
Check the price of white turnips every day at Nook's shop twice a day, once before and once after noon. The price he will buy white turnips will be between 30 and 700 bells. Sell all of your white turnips if the price is above 400 bells. White turnips spoil at the end of Saturday, so waiting for a price much higher risks losing all the money invested if you get unlucky with Nook's prices.
Dig up the red turnip on Saturday.
Sell the red turnip to Nook. You will receive 16,000 bells as long as it was watered every day.
