Climate matters. This page is a practical baseline. Confirm cultivar, local frost/heat conditions, mature size and regional restrictions before planting.

Growing directions
Plant certified seed potatoes cut to egg-sized pieces (each with 1–2 eyes) 4 in deep in trenches spaced 30 in apart. Hill soil up around the stems as they grow, keeping tubers covered to prevent greening from light exposure. Water consistently and watch for late blight in humid weather — infected foliage should be removed promptly to protect tubers. Harvest new potatoes when plants flower, or cure full-season types for a week at room temperature before long-term storage.
Source and local conditions
Typical planning ranges from OpenPlantDB (CC0). Cultivar, climate, season and growing method can change these values. Confirm the seed label and local guidance before planting.
