Plan sweet potatoes for tested pressure-canning recipes using cited slip density, row yield, spacing, and warm-season planting guidance.
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.
Locally adapted orange- or light-fleshed cultivars
Choose disease resistance and days to maturity for the warm season; follow tested preparation and jar-size limits.
Planting and indoor-start timing
Plant slips after frost danger when soil is thoroughly warm. Allow enough frost-free time for root development and curing before storage.
Current weather is not loaded automatically; check the local forecast and soil before planting.

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.
