Spring planting dates

“Plant out” means transplanting for crops started indoors and sowing or planting directly in the garden for the others. Each column applies CSU Extension's timing rule to a different last-frost anchor: aggressive = typical date (Feb 1, 50% risk), balanced = Feb 15 (30%), safe = Mar 3 (10%). For hardy crops the cell shows the CSU “as early as” window.

Before sowing, check the soil too. CSU recommends taking its temperature at 4 inches (6 inches for beans). Since NOAA publishes no soil-temperature normals, we give CSU's minimum soil temperature for each crop rather than a date.

Fall planting dates

Latest dates for a fall harvest, using the University of Nebraska–Lincoln Extension count-back formula: days to harvest (CSU) + 14-day fall factor + 14-day frost-tender factor for frost-sensitive crops, counted back from the first-frost date. For transplanted crops (CSU days are from transplant) the result is the latest transplant date; seeds go in CSU's transplant-age weeks earlier. We add no harvest period, so these dates give you a first harvest by the first frost, not a long harvest.

Crop-by-crop notes

When to plant tomatoes in Jacksonville

Very tender crop. CSU Extension's rules are to set tomatoes out at least 2 weeks after the average last frost and only once nights are above 52°F. In Jacksonville, the frost rule alone would allow about Feb 15, but the average nightly low at Jacksonville NAS first rises above 52°F on Feb 26, so the dates shown start no earlier than that: about Feb 26 using the typical date, Mar 1 as a balanced choice, or Mar 17 if you go by the safer 10% date. Start seeds indoors Jan 11–25, 5–7 weeks before transplanting on Mar 1. Fruit set suffers when nights drop below 55°F (CSU). The normal low at Jacksonville NAS reaches 55°F on Mar 16. Set out on Mar 1, tomato plants would start producing around May 5, based on CSU's typical 65 days from transplant to harvest. That leaves 245 days before the typical first frost (Jan 5).

When to plant peppers in Jacksonville

Very tender crop. CSU Extension's rule is to set peppers out at least 2 weeks after the average last frost. That's about Feb 15 using the typical date, Mar 1 as a balanced choice, or Mar 17 if you go by the safer 10% date. Start seeds indoors Jan 4–18, 6–8 weeks before transplanting on Mar 1. Below 55°F at night, fruit set suffers (CSU). At Jacksonville NAS, the normal low reaches 55°F on Mar 16. Using CSU's typical 70 days from transplant to harvest, pepper plants set out on Mar 1 would start producing around May 10. That's 240 days before the typical first frost (Jan 5).

When to plant potatoes in Jacksonville

Semi-hardy crop. CSU says potatoes can be planted as early as 0–2 weeks before the average last frost, in soil of at least 45°F. In Jacksonville, that's roughly Jan 18 – Feb 1 going by the typical date, or Feb 17 – Mar 3 going by the safer date.

FAQ

When should I start seeds indoors in Jacksonville?

Sow tomatoes indoors Jan 11–25 and peppers Jan 4–18. We work back from a balanced (30%-risk) transplant date using CSU's transplant ages.

When should I plant tomatoes outside in Jacksonville?

CSU Extension's rules for tomatoes are 2+ weeks after the average last frost and nights above 52°F.
