When planting potatoes, the recommended spacing depends on the potato variety and growing method, but general guidelines are as follows:
- Within rows: Plant seed potatoes about 12 inches (30 cm) apart for most varieties. Larger varieties like russets may need spacing of 12 to 15 inches (30 to 38 cm), while smaller varieties such as fingerlings can be spaced closer, around 8 inches (20 cm) apart
- Between rows: Rows should be spaced about 30 inches (75 cm) apart to allow enough room for hilling, air circulation, and ease of harvesting. Some sources suggest 30 to 36 inches (75 to 90 cm) between rows, especially for main crop potatoes
- In raised beds or containers: One potato plant per square foot (12 inches apart) is common, but larger potatoes may need more space, up to 15 inches apart
Planting potatoes too close together can reduce tuber size, increase competition for nutrients, and raise the risk of diseases like blight due to higher humidity around plants
Summary of Potato Planting Distances
Spacing Aspect| Typical Distance| Notes
---|---|---
Between seed potatoes| 8–15 inches (20–38 cm)| Smaller varieties closer;
larger need more space
Between rows| 30–36 inches (75–90 cm)| Allows room for hilling and airflow
Raised beds/containers| ~12 inches (30 cm)| One plant per square foot
These spacing guidelines help maximize yield by balancing tuber size, plant health, and ease of cultivation
