The sweet potato is a fall crop in Harvest Moon: Back to Nature. It is arguably the best crop in the game, which can bring you a ton of gold during fall. You will be rich in no time thanks to the sweet potato’s fast growth rate and price per crop.
Crop Information
Season: Fall
Where to buy Seeds: At the Supermarket
Days to Grow: 5 days
Renewable Crop: Yes, 3 days to regrow
Important Note: Each bag of seeds has 9 seeds that will fill a 3×3 square of tilled soil when planted. If you plant any seed on untilled soil, it will not grow and you will lose it forever.
Profit Using 3×3 and Fat-C Method
For renewable crops, we will calculate the profit per bag per day with the formula (Maximum Profit per Season/30 days), assuming you started planting on the first day of the season.
| 3×3 Square | Fat-C Method | |
| Seed Bag Cost | 300G | 300G |
| Price per Crop | 120G | 120G |
| Total Revenue per Bag | 1080G | 960G |
| Profit per Bag per Day | 314G | 278G |
| Maximum Harvests per Season | 9 times | 9 times |
| Maximum Profit per Season | 9420G | 8340G |
The Fat-C Method
This planting method involves tilling a 3×3 square of soil and leaving one square on the edge untilled, planting just 8 crops instead of 9. This is the most efficient method of planting crops during the early stages of the game since the center crop is inaccessible without an upgraded watering can.
