The recommended spacing for planting potatoes varies somewhat depending on the potato variety and growing method, but general guidelines are as follows:

• Plant seed potatoes 10-12 inches apart within the row if cut into pieces, and 12-16 inches apart if planting whole larger potatoes to allow for bigger plants

• Rows should be spaced about 30-36 inches (2.5 to 3 feet) apart to allow for hilling and growth

• For early or salad potatoes, a spacing of about 30 cm (12 inches) between plants and 60 cm (24 inches) between rows is typical; maincrop potatoes require more space, about 40 cm (15-16 inches) between plants and 75 cm (30 inches) between rows

• In raised beds or containers, spacing can be closer, about 12 inches between plants, since space is limited and plants can be smaller

• For new potatoes, closer spacing around 8-9 inches is possible, but for larger storage potatoes, spacing up to 20 inches between plants is recommended

In summary, a good rule of thumb is to plant potatoes about 10-12 inches apart in rows spaced 30-36 inches apart, adjusting slightly based on potato variety and growing conditions. Closer spacing is possible for small or early potatoes and in raised beds, while larger potatoes benefit from more space to grow bigger tubers
