Potato in a Zone 10 season

Zone 10 gives about 318 frost-free days. Potato needs roughly 90 days from sowing. That leaves about 228 days of slack, so there is room for a late start or a second planting.

How to grow potatoes

Plant seed potato pieces, each with an eye, about a hand's width deep once the soil is workable and no longer cold and soggy. Hill soil up around the stems as the plants grow. Tubers stall in hot weather, so aim for the cooler part of the year.
