How to get red turnips
Between 6AM and 12PM on any Sunday Joan the turnip seller will be in your town. Talk to Joan and buy a bag of red turnip seeds from her. You can store those seeds for as long as you want. They will not become rotten. A pack of turnip seeds costs 1,000 bells. She also sells white turnips.
How to plant and grow red turnips
When you are ready to grow red turnips, dig a hole outside with your shovel, then plant the bag of red turnip seeds. Be sure to use your watering can to water the seeds. Otherwise, the turnips will go rotten in the ground the next day. You have to water your red turnip seeds every day until you are ready to dig them up.
What to do with red turnips
The red turnips will grow at little bit each day, becoming fully grown after being underground for 6 days. If you bury the red turnip seeds and then dig up the red turnip on the same day that you plant it, you can sell it for only 2 bells. If you dig up the red turnip on the next day, you can sell it for 100 bells. The following table shows you the price details.
| Days planted | Sell price |
|---|---|
| 0 | 2 |
| 1 | 1000 |
| 2 | 500 |
| 3 | 2,000 |
| 4 | 4,000 |
| 5 | 8,000 |
| 6 or more | 16,000 |
Note: if you want to give Wendell a red turnip for food, it's OK to plant the seeds and then dig up the turnip right away. Wendell will eat it.
