Plan white potatoes for tested pressure-canning recipes using cited row yield and spacing while keeping prepared size and variety separate.
Your growing location
Hardiness zone describes winter minimum temperature. It does not replace frost dates, day length, soil temperature, or current weather.
Nothing is shared until you choose a lookup button. ZIP lookup uses PHZMAPI. “Use my location” sends coordinates to BigDataCloud only to obtain a ZIP, then sends that ZIP to PHZMAPI; coordinates are not stored by this site.
Verify the result on the official USDA 2023 map; manual override always remains available.
Plants and space calculator
Space by planting style
Preservation-suitable variety direction
Zone is only one factor. Day length, disease pressure, storage quality, maturity, and use may be more important.
Waxy white or red potatoes
Often hold shape well when cubed; use sound, mature potatoes and follow the tested recipe’s preparation and jar-size limits.
Planting and indoor-start timing
Plant certified seed potatoes in the regional window when soil is workable and no longer excessively cold or wet. Use local disease and frost guidance.
Current weather is not loaded automatically; check the local forecast and soil before planting.
Canning recipes using potatoes
Sources, formulas, and limits
Plants = household annual target ÷ selected yield per plant, rounded up. Area or row units = target ÷ compatible cited yield, rounded up. “Typical” uses the cited midpoint.
