Plan eggplant for tested pickles, relishes, and mixed products using cited transplant density, row yield, spacing, and warm-season timing.
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 productive eggplant
Choose disease resistance, fruit type, and maturity for the frost-free season; use only a tested recipe intended for eggplant.
Planting and indoor-start timing
Set transplants after frost danger when soil and nights are reliably warm. Use the local forecast and days to maturity rather than zone alone.
Current weather is not loaded automatically; check the local forecast and soil before planting.

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.
