Potatoes generally take about 70 to 120 days to grow from planting to harvest, depending on the variety and growing conditions.

• Early potatoes mature faster, typically in about 70 to 90 days, and can be harvested as early as June or July. These are often smaller and best eaten soon after harvesting as they do not store well

• Second early potatoes take slightly longer, usually ready by July or August

• Maincrop potatoes require the longest growing time, about 90 to 120 days, and are harvested from late August through October. They produce larger tubers and store well for several months

The potato plants are ready for harvest when the foliage dies back and turns yellow. At this point, the tubers have matured and can be carefully dug up

. In summary, the time it takes for potatoes to grow depends on the type:

• Early potatoes: ~70-90 days
• Second earlies: ~90-100 days
• Maincrop potatoes: ~90-120 days

Harvest timing also depends on local climate and planting date, but generally ranges from early summer to autumn
