How many potatoes does one plant typically produce?

A healthy potato plant yields roughly 0.5 to 2 pounds (0.2–0.9 kg) of potatoes, depending on variety, soil fertility, watering, and growing season length. High-yielding varieties in optimal conditions can reach 2–3 lbs per plant.

What is a typical in-row and row spacing for potatoes?

Most gardeners plant seed potatoes 10–12 inches (25–30 cm) apart within a row, with rows spaced 24–36 inches (60–90 cm) apart. Closer spacing increases plant count but may reduce individual plant yield.

How many seed potatoes do I need per plant?

Each planting hole receives one seed potato or one cut piece with at least one eye. This tool assumes a 1:1 ratio of seed potatoes to plants, so the seed count equals the plant count.

Why does the estimate differ from my actual harvest?

Actual yield depends on soil quality, variety, irrigation, pest pressure, and growing season length. The estimator provides a statistical average based on your inputs — treat it as a planning guide rather than a guarantee.

Can I use this for container or raised-bed growing?

Yes. Enter the usable surface area of your container or raised bed. Note that containers with less than 12 inches of soil depth may reduce per-plant yield; adjust the yield-per-plant slider downward to compensate.

Does the tool account for crop loss or culling?

The base estimate reflects gross yield. Use the Loss % field to deduct a percentage for culls, damaged tubers, or storage loss to see a net usable yield figure.
