Most potatoes take about 70–120 days (10–17 weeks) from planting to harvest, depending on the variety and growing conditions.

Quick Scoop

  • Early or “new” potatoes: usually ready in about 70–90 days after planting.
  • Maincrop/baking potatoes: often need 90–120 days to fully mature and bulk up underground.
  • Warmer soil, good sunshine, and steady moisture help them grow on the faster end of that range.

A simple way to picture it: if you plant in early spring, you can often start pulling small baby potatoes by early summer, and dig big, fully grown spuds a few weeks later once the plants yellow and die back.
