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

• New potatoes (small, immature tubers) can be ready as early as 8 to 10 weeks (about 60 to 70 days) after planting

• Full-sized potatoes usually take about 80 to 100 days to reach maturity, with some varieties maturing faster (early-season types in 75-85 days) and others taking longer (late-season types up to 120-125+ days)

• The growing cycle involves sprouting within 10-20 days, flowering at 40-60 days, tuber formation starting roughly 15-30 days after emergence, and tuber filling out between 45-90 days

• Harvest is generally done when the plant foliage yellows and dies back, signaling tuber maturity

In summary:

• Early varieties: 75-85 days
• Mid-season varieties: 90-100 days
• Late varieties: 105-125+ days

The exact timing depends on the potato type and local climate, with potatoes needing adequate heat, sunlight, water, and nutrients for optimal growth

. Thus, plan for about 3 to 4 months from planting to harvest for most potatoes, with new potatoes ready sooner and storage potatoes requiring the full growing period.
