Planting and Spacing

Planting dates in Utah vary depending local climate conditions. Planting often begins in late March in southern Utah and may be as late as earlyJune in cooler areas of northern Utah. Planting is recommended after danger of frost has passed. Local freeze dates can be accessed through the Utah Climate Center (climate.usurf.usu.edu).

Potato seed requirements depend on between and inrow spacing (Table 8.2), variety, and local conditions. Close spacing (6 - 8”) are used to reduce tuber size and increase the number of tubers set. Closer spacings also reduces hollow heart and growth cracks. Seed pieces should be planted 2 - 4” deep. For more rapid emergence, plant shallow. If soils are dry, plant a bit deeper. Rapid emergence is necessary to reduce soilborne diseases such as Rhizoctonia.
